Hello everyone, I guess I haven't really actually written any messages lately, but that doesn't mean I don't keep up with discuss-lfm. There have been many valuable suggestions made that I have used and responded to individually and have greatly appreciated all the ideas, etc. My year started out with Mars and/or solar system activities. We made a scale model, by size, of the solar system, and we made an animated (using the students) scale model, by distance, of the solar system (good excuse for going outside.) Using some video from last year we watched the launches of the MGS and the Pathfinder and other informative tapes I had, and we did a multimedia exploration of the two missions using the Mars Navigator CD-ROM, some packets I got from AZ k-12 Mars Educational materials, and the internet. We did some simulations of how some of the instruments on the MGS worked. I think I posted my idea of the TES instrument using light boxes last year. If anyone is interested I could repost. I made up an MOI and aerobraking activity the students did outside so they'd understand it. One person was "Mars" and one person was the "MGS". Then about two thirds of the class held hands on one side of "Mars" and the other third held hands on the other side. They represented Mars's atmosphere. Holding hands showed how gravity held the atmosphere to "Mars". Then "MGS" came running toward the last person on the long side of "Mars" and, with their own power, slowed down to be grabbed by him/her. After being slowed down, "MGS" orbited "Mars" in a very elliptical orbit going under the raised hands of the "atmospheres". With each orbit "MGS" got closer and closer to "Mars" until he/she formed a circular orbit fairly close to "Mars". The kids had a great time and took turns being "Mars" and "MGS". We participated in a web chat with Ken Edgett. We had learned about his TES and how it worked so we enjoyed meeting someone we had been learning about. Unfortunately the web chats come at a very awkward time for our schedule, but I do hope to participate in more in the future. I was involved in Red Rover Red Rover last year and kept the rover and the landscapes so my studentsthis year had the opportunity to control the rover. I arranged an interdisciplinary activity with Social Studies teacher. We put grid marks on the landscapes from last year. Then students in the Soc. Studies room, controlled the rover for the purpose of finding three rocks placedon the landscape by students who were in my room. When they found a rock they were to plot it on graph paper according to the grid, to name it, and to describe it. Does this sound like a Sojourner simulation? Well that's what it was. The students had lots of fun doing this activity. We even had technical difficulties we had to adapt to. Sound familiar? I am trying to do this activity with the 7th graders so they have a follow up acitivity from last year. I'm working with the TAG teacher. We started WEATHER WORLDS doing research with books, Mars Navigator CD-ROM, and sites on the internet. I used Mike Reynolds's idea for teams, and the students seemed to enjoy this method. We haven't quite gotten our proposal posted, but hope to do that tomorrow. Other curriculum duties/responsibilities interrupted our progress for WW. Since we didn't really see the form for posting our proposal for WW, it might not follow it exactly because we may not have gone into as much depth as the form really requires. But we'll submit our proposal with what we have, and it has been a good learning opportunity no matter what. We look forward to the rest of the project. I like Ginny Dexter's organization too, and I think I'll use it for when we gather the data. I am now doing other curriculum units, but will take time out when necessary for WEATHER WORLDS. Thanks everyone for all the help, and Live From Mars is alive and well here at Sioux Center Middle School in Iowa. Lucy Marske, 6th grade teacher Sioux Center Middle School Sioux Center, IA
