    A warm welcome to our newcomers on debate-lfrf. The website [if you
    haven't seen the "new" expanded site, visit at: ] is officially up and running.

    The archives of debate can be found on the website by going from the front
    into Interact, followed by Collaborative Projects. There you will find a
    link to browse DEBATE-LFRF-DIGEST Archives. They are easily accessible and
    provide a quick guide to all prior debate conversations and information.

    With the teachers' guides on their way, we're all getting excited about the
    project. Let us know about your ideas for the Backyard Biodiversity
    Survey. Feel free to contact either of us with any questions or problems.
    We're looking forward to an energetic online project and debate.

    From our backyards.....where the weeds are outnumbered only by the cobbles
    and gravel....

    Hi! We are students in a charter school in Chandler AZ, a suburb of
    Phoenix. We are in a 4th, 5th , 6th grade classroom and we are Kyle,
    Adam, Erin, Kristy, Heather, TJ, Andrew, Brianna, Sagan, Ashley, Jake,
    Jacqee, Tyler and Ariel. Yesterday, Tuesday, March 24 at 1:30 p.m. MST
    we went to a field north of our school. We don't really have a
    playground yet. It is under construction as this is the first year of
    our school and we are in a strip center. This field has been used
    privously for agriculture and is slated for development. Chandler is
    located at 33 17 min 45 sec N, 111 54 min 53 sec. W. It was 85
    yesterday, sunny and warm. We found 3 dad lady bugs and one live one.
    We found a lot of grass and ragweed, some small pods, cracked earth
    (Unusual because we have had lots of rain this spring) pine needles
    (under thepine tree), epbbles, beetle, a huge made-made rock (old
    concrete), thorns and bird droppings. We expected to see more bug than
    we idd alothough some of the girls collected a bund of tiny green bugs
    on their socks. We live in the desert which is as far away from the
    rain forest as you can get. Friday we are going on a field trip to a
    graden show which will include an 1800 sq ft tent with over 1000
    butterflies-at least 12 types. We will let you know what it's like!!
    Bye for now.

    Survey Design Consensus Begins Next Week!

    From: (debate-lfrf-digest)

    Back to top

    Dear Debate-lfrf Members,

    We have one more thing we need to discuss before we begin our discussion
    next week on how to put together the final design for the survey. One of
    our suggestions for the survey is to have the students go out and take
    their survey and then two weeks later go out and take it again to see what
    changes they observe. In order to do this accurately it will be important
    that the students survey the same square meter. An idea that we came up
    with is to replace the meter sticks with string. The groups could then pick
    a natural landmark that would remain stationary (a rock or a particular
    patch of plants) or place a marker in the ground and use that as the
    center. The string could then be placed around the landmark in the form of
    a circle. The problem this presents is that it is more difficult for the
    students to graph a circle than a square. If we place the string in a
    square how important is it that the corners be square? Will the groups be
    able to recreate their square meter as easily as they can with the circle?

    As we begin to move into the final stages of our survey design it is
    important that we hear your suggestions. One of the best things about PTK
    projects is their flexibility to be implemented in a wide range of grade
    levels and classroom situations. Each classroom has its own unique
    characteristics and we want this project to be a rewarding experience for
    you and your students. Communication is what helps us accomplish this goal.

    If you have any questions or concerns about this activity please feel free
    to contact us. Send an e-mail message to Susan Hurstcalderone
    or Eileen Bendixsen and we will
    promptly respond.

    Our school backs up on the Garden State Parkway and one of the town
    recreation fields is on the side. We could not leave out the strings
    either. The string would be picked up when you finish collecting your
    data at the first visit. We need to come up with an easy way for
    students to be able to go back to the same spot to survey the second
    time. That is why I suggested the landmark as the center. Something that
    would not change in two weeks, so that the students know where to place
    the string the second time.

    Deb's idea about making maps is an excellent idea. Does anyone else have
    any good suggestions that have worked for them in the past?

    I believe we need to do this in 15-20 minute observations if we have
    any time limit on them. The main reason I see a need for a time limit
    is to not allow too many "mobile" insects to roam around and confuse
    those trying to count. Another reason may be to not eat up too much
    class time.

    The data that should be collected is time, temp, location (lat and
    long), surrounding landforms or markers (roads, forests, lakes, etc).

    All things living and dead should be included. They were once (and
    really still are) part of the ecology and are therefore part of the
    biodiversity of the area.

    Common name is great, but some family name or genus/species should
    also be included because common names vary for the same species from
    place to place.

    My school is located in North Carolina, and we have Chapel Hill going
    to the final four (I think they are going, aren't they?). We are west
    of them, however- in the foothills of the Appalachians.
    We also have had sunshine for 2 days (no more) in a row, and all my
    classes love to go outside every day if they could!

    I hope this is what you needed!

    From Size to Time

    Last time we decided to conduct our surveys using a square meter.....It
    seems that many of us still are experiencing a wide range of weather
    conditions and those conditions can change rapidly. However, those that
    did make it outside used a square meter in which to conduct their surveys.
    Now lets look at how long a time period we should spend collecting data
    when we do go out to conduct the survey.

    How long a time period per observation will you use when you survey your

    _____time per observation

    Is it important to have everyone using the same amount of time? Why or
    why not?

    What data should be collected?

    Should we count every thing we find?

    What if we find something that was living but is not living now? Do we
    count it in our survey?

    How do we count plants? Is each plant counted separately? Or do we count
    only the kinds of plants? For example, grass. Do we record 987 grass
    blades or 1 kind of grass? What do you think we should do?

    How should data be recorded?
    common name
    scientific name -- genus and species
    family name

    This time, can we hear from a class that:

    *is south of the Mason-Dixon Line

    *falls along the 45 degree of latitude [+ or - 5 degrees]

    *lives in an area which has a team in the final four

    *has had sunshine for two days in a row

    *likes to be outside for class activities

    Try to have your posts online by 3:00 p.m. est Wednesday, March 25th.

    Have fun........
