Standard One
Nature and Application of Science and Technology

Science as Inquiry

 

By the end of the third grade students should know that:

 

1. Scientists’ curiosity about the natural world leads them to ask questions about how things work. In order to answer these questions, scientists observe and explore things carefully.

Develop a list of questions raised by the class about nature and the immediate surroundings. In a discussion, determine which questions the class has the capability of answering. The development of the answers involves observation and measurement, collection and sorting of samples, and taking things apart and putting them back together.

2. Scientists sometimes observe the same object or event and describe it differently. It is important for scientists to describe things as accurately as possible in order to compare their observations .

Work in small teams to develop answers to the questions posed by the class about the natural world. Compare similarities and differences in each team’s observations, descriptions, measurements, and methods of classification. When large differences exist in the results, repeat the procedures to settle the differences, and speculate on the reasons for the differences.

Grades 4-5

Standard One
Nature and Application of Science and Technology

Science as Inquiry

 

By the end of the fifth grade students should know that:

 

1. Curiosity about nature and the world around us leads scientists to ask questions in a way that requires scientific investigation in order to develop an explanation. The breadth and style of this investigation depend on the questions asked.

Ask reasonable scientific questions about a topic of interest and decide what information is needed to answer these questions. For example, how does the amount of sunlight a plant receives affect its growth? What can the class do to reduce cafeteria waste? Do some substances dissolve in water faster than others? Is there always a full moon on the same day of each month?

Flow of Matter and Energy

 

1. All living organisms interact with the living and non-living parts of their surroundings to meet their needs for survival. These interactions lead to a constant exchange of matter and energy. Plants derive energy from the sun for growth and survival. Animals eat plants or other animals that have also eaten plants to satisfy energy needs. When plants and animals die, they are eaten by decomposers.

Develop a list of food items offered for lunch by the school cafeteria. Work in groups to construct a food chain that traces the source of each food item from plant origin to the product eaten.

Diversity and Continuity of Living Things

Heredity and Reproduction

 

By the end of the fifth grade students should know that:

 

1. Physical characteristics are passed on from parent to offspring. Organisms with two parents inherit characteristics of both.

Observe parents and offspring from a variety of species (e.g., hamsters, mice, fish) and draw reasonable conclusions about the inheritance of traits such as body shape, coloration, and behavior.

video

online

Diversity

 

1. Organisms have many distinct and unique features which they use for survival. Specialized features include those for finding food, building shelters, evading predators, and reproducing. Scientists use similarities and differences in these features to classify and group organisms.

Examine a variety of common plants and animals for similarities and differences in features such as animal tracks, beak shape, leaf structure. Use the similarities and differences of the features to develop appropriate classifications that sort and group these organisms. For example, birds can be categorized according to the shape of their beaks and the type of food they eat (e.g., berry eaters, seed eaters, meat eaters).

Ecology

Interactions Within the Environment

 

By the end of the fifth grade students should know that:

 

1. All living organisms interact with the living and non-living parts of their surroundings to meet their needs for survival. These interactions lead to a constant exchange of matter and energy. Plants derive energy from the sun for growth and survival. Animals eat plants or other animals that have also eaten plants to satisfy energy needs. Dead plants and animals are eaten by decomposers.

Illustrate a food chain or a web of food chains by sequentially ordering pictures or samples of a variety of living things (e.g., fungi, insects, plants, animals). National Geography Standards 1994, Physical Systems p. 120.

2. Changes in an organism’s environment can either be beneficial or harmful. Organisms may be affected by other organisms, by various physical factors (e.g., rainfall, temperature), by physical forces (e.g., storms, earthquakes), and by daily, seasonal, and annual cycles.

Investigate how a particular environment (e.g., field, playground) changes over time. Classify the changes as either resulting from physical forces or from the action of living organisms, and determine whether the changes are beneficial or harmful to the organisms.

Plan and conduct simple investigations to explore how modifications in the physical condition of a plant’s environment (e.g., moisture, temperature, soil, air) affect its growth and survival. Explain how the results of the investigation apply to other organisms.

Grades 6-8

Standard One
Nature and Application of Science and Technology

Science as Inquiry

 

By the end of the eighth grade students should know that:

 

1. The design of an investigation, in many cases, is determined by the type of questions asked. Therefore, the thoughtful and informed structuring of such questions is an important part of scientific inquiry. For example, a question such as, “What are the similarities and differences among the plants that grow in this region?” requires a taxonomic investigation in which plants are collected, identified, and classified. On the other hand, answering – “What was the reaction of Marie Curie’s contemporaries to her work and accomplishments?” – may involve consulting, reviewing, and discussing both contemporary and historical publications as part of an investigative design. However, an experimental investigation in which systematic observations are made and where data are used and analyzed to construct an explanation could result from a question such as, “How do the physical properties of local soil samples lead to differences in drainage or percolation?”

Expand the learning event highlighted in A-1 grades 4-5. Ask reasonable, relevant, and testable scientific questions about topics of interest and determine the type and complexity of the investigation required to answer them.

video
hands-on
online

2. The ultimate goal of any scientific investigation is to obtain evidence precise and thorough enough to answer a question. Various experimental designs and strategies can be developed to answer the same question. The comprehensiveness and sophistication of the investigation depend on the tools and technologies used.

Conduct a series of investigations with sufficient complexity to require the use of various experimental techniques and strategies; the separation and control of variables; the consolidation, organization and display of data; the development of conclusions; and the posing of additional questions. Develop oral and written presentations of the investigation to allow peer review of the results.

Develop the competence to use a variety of tools and techniques in order to solve a wide range of practical problems. Examples follow:
- Use calculators to compare amounts proportionally (e.g., proportion of fat, protein, carbohydrates in foods).
- Use computers to store and retrieve information in topical, alphabetical, numerical, and key word files and to create and manipulate individual files.
- Read analog and digital meters in instruments used to make direct measurements of length, volume, weight, elapsed time, and temperature and choose appropriate units for reporting magnitudes.
- Use cameras and tape recorders for capturing information.

video

online

3. Explanations in science result from careful and logical analysis of evidence gained from an investigation. Explanations relate causes to effects and develop relationships based on the evidence. Critical analysis of data is necessary to judge the quality and validity of the proposed explanation. Critical analysis skills learned in the classroom can be applied to judge the validity of claims made in everyday life.

As part of an investigation, use a variety of strategies to construct and develop logical explanations including:
- Deciding what evidence from an investigation is useful.
- Organizing and summarizing information and data in tables and graphs in order to identify relationships.
- Incorporating pie charts, bar and line graphs, two way data tables, diagrams, and symbols into written and oral presentations.
- Forming a logical argument about the cause and effect relationships in an investigation.
- Retrieving pertinent information from reference books, newspapers, magazines, compact discs, and computer data bases.
- Constructing models in order to visualize and explain the relationship among various elements of a product, process, or system.

Review and critically analyze claims made in popular magazines such as PEOPLE, TIME, DISCOVER, and in newspapers, television news programs or specials, to determine the validity of the claims and conclusions.

Science, Technology and Society

 

1. Social, cultural, environmental, scientific and technological strengths, and economic factors influence which scientific and technological areas are pursued and invested in. At the same time, the scientific discoveries made and technologies developed directly influence society and its habits, organization, and cultural values.

Investigate the relationship of factors such as resource availability and cultural tradition on the kinds of science and technologies pursued. Examples could include:
- An analysis of transportation methods and expertise around the world. The emphasis on mass transportation in Europe and Japan vs. the super highway system in the U.S. The emergence of Great Britain as a sea power.
- The emergence of the United States as a world power in the polymer industry.
- The global war on cancer and other serious diseases.

2. The issues surrounding science, technology, and society are complex and involve many risk/benefit considerations. Even though new technology may provide a solution to an important problem, its impact on human health, the environment, and social dynamics needs to be analyzed.

Explore and discuss various problems which have faced society and the technologies developed to deal with such problems. Identify the products and processes developed to solve these problems and consider the benefits delivered and the risks created by these new technologies. Such areas could include the management and control of sewage, the preservation of food, the fighting of tooth decay, the development of various modes of transportation, and the heating or lighting of homes.

History and Context of Science

 

1. Over the course of human history, science has been practiced by different people in different cultures. Unfortunately, women and minorities have often been discouraged or denied the opportunity of participating in science because of education and employment prejudices or restrictions. 

Research the life, work, and contributions of a contemporary or historical scientist. Compare the background, human qualities, and factors that influenced the work of the scientist as part of a discussion of contemporary and historical variations of people who practice science.

Explore the historical under representation of women and minorities in many fields of science and engineering, and the strategies that education, business, and government in Delaware are employing to increase their representation in the scientific work force of the future.

2. People engaged in doing science are found in many occupations and institutions such as hospitals, universities, classrooms, industry, and farms. The nature of scientific investigation often requires that teams of individuals with different abilities work together to solve a problem or to understand the natural world.

Participate in visits to local facilities where science is practiced or participate in a class discussion with community individuals, including women and minorities, who work in science related occupations. Report and discuss the variety of opportunities for practicing science.

Investigate research projects which have been or are presently conducted in the State of Delaware (e.g., agriculture, material, medical, marine). Explore how individuals with different abilities contribute to the success of these projects.

Life Processes

Structure/Function Relationship

 

By the end of the eighth grade students should know that:

 

Matter and Energy Transformations

 

1. Plants make their food by the process of photosynthesis. Using light energy, green plants convert water and carbon dioxide into energy-rich simple sugars and oxygen. Sugar is the source of food used by most plants, and ultimately, by all other consumers. Oxygen produced during photosynthesis is required for the survival of most plants and animals.

Conduct simple experiments with green plants to determine the requirements and products of photosynthesis. For example, place elodea in a clean inverted funnel and place both the elodea and funnel in a beaker of water. Place a test tube over the spout end of the funnel and measure oxygen bubble production as evidence of photosynthesis.

Determine the amount of oxygen produced from an aquatic green plant such as elodea. Prepare two containers with equal amounts of water and green plants. Place one container in sunlight and the other in the dark for several hours. Test for dissolved oxygen produced by the plant using a LaMotte or Hach D. O. Kit.

Heredity

 

By the end of the eighth grade students should know that:

 

Evolution

 

1. Natural selection is the process by which some individuals with certain traits are more likely to survive and produce greater numbers of offspring than other organisms of the same species. Conditions in the environment can affect which individuals survive in order to reproduce and pass their traits on to future generations. Small differences between parents and offspring accumulate over many generations and ultimately new species may arise.

Conduct a natural selection simulation to demonstrate that a specific trait has selective advantages for an organism. For example, study the advantages of protective coloration of a species that is preyed upon. Scatter different colored toothpicks in the grass, role play a predator, and quickly pick up as many toothpicks as possible. Collect data on the remaining colors and discuss the advantages of protective coloration in the survival of organisms.

Investigate and discuss how short term physiological adaptations of an organism (e.g., skin tanning, muscle development, formation of calluses) differ from long term evolutionary adaptations that occur in a group of organisms over generations.

Diversity

 

3. Each structure in an organism is uniquely adapted to perform a particular function for enhancing the ability of the organism to survive. The great variety of body forms found in different species enable organisms to survive in diverse environments.

Examine selected internal and external structures of different plant and animal species. Describe and compare those structures that perform a common function, (e.g., teeth of herbivores/carnivores, leaves in deciduous trees/conifers, breathing organs in aquatic animals/terrestrial animals) and explain how differences in each structure enables the organism to survive in its particular environment.

Standard Eight
Ecology

Structure/Function Relationship

 

By the end of the eighth grade students should know that:

 

1. An ecosystem consists of all the organisms that live together and interact with each other and their physical environment.

Investigate and describe multiple ways that species may interact in an ecosystem. Apply this knowledge to populations of a local habitat in order to identify and classify the relationships observed (e.g., predator/prey, producer/consumer, parasite/host, and mutualism).

video
hands-on
online

2. Interactions in an ecosystem result from the transfer of matter and energy from producers to consumers and eventually to decomposers. The total amount of matter and energy in the system remains the same even though its form and location changes.

Construct diagrams of food chains to trace the flow of matter in a local ecosystem and to categorize the organisms of the food chain according to the function they serve (e.g., producer, consumer, decomposer). Use several food chains to design a food web (food chains connected together) that would illustrate the interrelationships among the organisms.

video
hands-on
online

3. Matter is recycled in an ecosystem, and energy which enters the system as sunlight is either stored in the bodies of organisms, used by consumers to support their activities, or dissipated to the environment as heat energy. Loss of heat from an ecosystem is compensated for by continuous input of solar energy.

Design food webs that include humans. Discuss how matter is recycled and energy is lost in each step of the food web and the implications of this loss on the food supply for an increasing human population.

video
hands-on
online

Change in Ecosystems

 

1. Changes in the physical or biological conditions of an ecosystem can alter the diversity of species in the system. As the ecosystem changes, populations of organisms must adapt to these changes, move to another ecosystem, or become extinct.

Investigate local areas (disturbed and undisturbed) that are undergoing natural cycles of succession such as abandoned gardens, uncut areas beneath power lines, areas along ditch banks and fences, and the edge of a forest. Predict how plant communities that grow in the area may change over time and how their presence determine what kinds of animals may move into or out of the area.

Contact the Department of Natural Resources or a wildlife agency to acquire information on animals or plants that have been introduced to Delaware. Investigate issues that relate to the introduction or re-introduction of a species into a local habitat (e.g., How and why the species was introduced into the area? If the species was re-introduced, what previously happened to the animals or habitat to cause their disappearance from the area? What indicators, if any, are there that the transplant was successful?)

video

2. The size of populations in an ecosystem may increase or decrease as a result of the interrelationships among organisms, availability of resources, natural disasters, habitat changes, and pollution.

Determine the carrying capacity of a single species in a closed system (brine shrimp, fruit fly) by recording the changes in population size over a period of time. Plot the data on a graph and use the results to explain how carrying capacity affects the population growth of the system.

Research and analyze data on human population changes of a specific Delaware area or county in 10 year increments over the last 100 years. Discuss reasons for the increase or decrease in population and how these changes have affected the biodiversity and availability of natural resources.

video

Interaction of Humans Within Ecosystems

 

1. The extinction or introduction of species can affect the stability of ecosystems. With careful planning, humans may be able to sustain ecosystems for their use as well as preserve their biodiversity and natural beauty.

Participate in food web demonstrations to predict the environmental impact of eliminating an organism from the food web. Discuss how the elimination or introduction of a species affects the entire ecosystem.

Research and discuss how human interactions have affected different plant and animal populations in Delaware (e.g., deer, phragmities, eagle, osprey, starling, multiflora rose), and explain how population changes have impacted the environment.

Discuss the roles and responsibilities of local, state, and federal environmental agencies. Contact several of these agencies for information on locally rare and endangered plant and animal species. Select a species and gather information about its particular situation (e.g., length of time endangered, past and present range, reasons it is endangered). Report on Delaware efforts to improve the chances of survival for the selected species.

Examine land use maps to identify and classify the uses of land (i.e., agricultural, residential, industrial) for a Delaware community or county. Investigate a specific local land use (e.g., wetlands and shore development, road construction, forestry, farming) and identify how the land use affects both humans and other organisms.

video
hands-on
online

2. Decisions about the use of natural resources are often determined by a society’s short-term needs for the resources with little regard for long-term consequences. The supply of natural resources such as water and petroleum is finite. Non-material resources (e.g., tranquillity, beautiful scenery) can not be easily quantified but must be preserved.

Survey friends, classmates, family, and extended family to determine if differences exist in attitudes about material and non-material resources. Discuss variations in the responses of the people surveyed and why decisions about the use of resources are often complicated and difficult to resolve.

Investigate Delaware’s wetlands as a vital resource and link to maintaining the water quality of the state and construct a wetlands model as follows: Punch many small holes in the bottom of several plastic bottles and fill half-full with different types of soil (e.g., sand, gravel, loam, humus). Place the bottle over an aluminum tray and pour a glass of water on the soil. Collect the drainage and pour the water sample over the soil several more times. Repeat the procedure for the different soil samples, and observe and discuss the changes in water appearance and odor following each treatment. Discuss the ability of wetland soils to filter sediments and pollutants.

Nature and Application of Science and Technology

Science as Inquiry

 

By the end of the twelfth grade students should know that:

 

1. The identification and formulation of appropriate questions guide the design and breadth of a scientific investigation. Based on the type of question(s) proposed, investigations explore new phenomena, solve science and technology related problems, compare different theories, resolve conflicts concerning societal issues, determine reasons for discrepancies in previous experimental results, or test the practicality of a consumer product.

Formulate scientific investigations from relevant questions and issues. Formulate questions to indicate conceptual insights and a depth of understanding around these questions and issues.

2. Scientific investigations in many cases follow no fixed set of steps. However, there are certain features of a valid scientific investigation that are essential and result in evidence that can be used to construct explanations.

Design and conduct a scientific investigation either as an individual or group activity. The investigation should be sufficiently complex to require the use of various experimental techniques and strategies; the separation and control of variables; the consolidation, organization and display of data; the development of conclusions; and the posing of additional questions. Develop oral and written presentations of the investigation to allow peer review of the results.

3. Tools and technologies extend human capabilities to perform investigations in more detail and with greater accuracy and improved precision.

Expand the capacity to use a variety of tools and techniques in order to solve a wide range of practical problems. Examples include:
- Following instructions in manuals or taking instructions from an experienced person to learn the proper use of new instruments.
- Using computers to produce tables and graphs and to make spread sheet calculations.

video

online

4. The close examination of evidence is necessary to construct logical scientific explanations and present arguments which defend proposed explanations. Such critical analyses of supporting evidence are not only important to scientific investigations but help in judging the validity of claims made in advertisements or concluded from investigative reports.

In an investigation, use various strategies to construct and develop logical explanations that:
- Decide what evidence from an investigation is useful.
- Use tables, charts, and graphs when making arguments and claims in oral and written presentations.
- Make and interpret scale drawings.
- Form logical arguments about cause and effect relationships in an investigation.
- Choose appropriate summary statistics to describe group differences, and indicate the spread of the data, as well as the data’s central tendency.
- Participate in group discussions on scientific topics by restating or summarizing accurately what others have said, asking for clarification or elaboration, and expressing alternate positions.
- Retrieve pertinent information from reference books, newspapers, magazines, compact discs, and computer data bases.
- Construct models in order to visualize the relationship of various elements of a product, process, or system.

Develop the practice of analyzing data, and considering claims by:
- Noticing and criticizing arguments based on the faulty, incomplete, or misleading use of numbers, such as in instances when (1) average results are reported, but not the amount of variation around the average, (2) a percentage or fraction is given, but not the total sample size (as in “9 out of 10 dentists recommend...”), (3) absolute proportional quantities are mixed (as in “3,400 more robberies in our city last year, whereas other cities had an increase of less than 1%), or (4) results are reported with overstated precision (as in representing 13 out of 19 students as 68.42%).
- Checking graphs to see that they do not misrepresent results by using inappropriate scales or by failing to specify the axes clearly. (Benchmark for Science Literacy, Project 2061)

5. Publication and presentation of scientific work with supporting evidence is part of the critique, review, and validation process conducted by the scientific community. The presentation of such work in accessible journals and reviews adds to the body of scientific knowledge and serves as background for subsequent investigations in similar areas. 

Write a senior thesis based upon a long-term scientific investigation. This report should present results and conclusions supported by an appropriate literature review. Defend this investigation before a panel of peers, teachers, and community leaders in a forum that allows critical analysis and debate.

Science, Technology, and Society

 

1. The practice of science and technology is not a linear process. In many cases, the desire of scientists to find what is real in nature creates opportunities for technology development. At the same time, technology provides scientists with tools and techniques that allow expansion of their capabilities and effectiveness.

Investigate a range of modern technological products and systems from the world. Identify those examples in which a scientific advance led to new technological opportunities such as discovery of DNA/biotechnology; splitting of the atom/nuclear energy and those examples in which technological advances led to scientific advances such as electron microscope/understanding of cellular detail; modern spectroscopy/better understanding of atomic and molecular structure.

History and Context of Science

 

1. Science is an international activity in which significant inventions and innovations have come from around the world. Even though scientists live and work in different cultures and come from different backgrounds, many of their activities are part of international collaborative efforts, and the knowledge created is shared in order to maximize the benefits to society.

Investigate various scientific concepts, inventions, and technological innovations that have been developed by different world cultures such as astronomy in Asia, or metallurgy in Africa. Discuss the influence of prevailing contemporary thought in various arenas (politics, religion, education) on the acceptance of these concepts, inventions, and innovations by other scientists and society.

Select a contemporary or technological challenge such as HIV, cancer research, space exploration, or ozone depletion. Explore the dimensions of the issue and the kinds of collaborative efforts that are in place to deal with it. Recognize that competence in the various scientific disciplines exists throughout the world and is not the province of a single country.

2. Science is divided into many disciplines such as astrophysics, biochemistry, and geophysics. Each discipline is a field of endeavor in itself and requires specialized training. Many of the tools, techniques, methods, and much of the knowledge created in one discipline are shared across disciplines in order to maximize the impact of the work.

Investigate the development of new scientific disciplines both historical, such as Lavoisier’s work in forming the foundation of modern chemistry, and contemporary such as molecular biology. Discuss how the development of a new scientific discipline influenced the work of other disciplines.

Select a major scientific discovery (e.g., DNA, transistor, x-rays, antibiotics) and discuss the influence of this discovery on the thoughts and work that followed in a variety of scientific disciplines.

3. Scientific theories are based on the body of knowledge that exists at any particular time. The driving force to explain nature motivates scientists to test the validity of these theories, and as a result, the mysteries of nature are continuously probed and explained as new theories are created.

Trace the evolution and progression of a theory surrounding an important area of scientific development such as structure of the atom, origin and evolution of the universe, or formation of Earth’s geological features. Discuss the important features of the most recent theory developed in this area and explain why it displaced the earlier ones.

Review selected scientific articles from popular magazines and newspapers such as New York Times, Science Times over an extended period of time. Identify a scientific theory that is currently being modified or debated based upon new data gathered by the scientific community. Discuss the interplay that exists between theory and the new information.
