I am getting ready to do a Science unit on the moon. For my observation, my princip[al would like to see math intergrated in the lesson. Any ideas ??????

How about 'fractions' of the moon which are visible? You could use Oreos. Well, maybe the Oreos wouldn't go over from an observation, but they'd be good later. You can google 'oreo moon phases' and a lot comes up.

PGE, I have had the class work in groups to figure out how many trips around the equator equal a trip to the moon. This has worked great with Grade 5 and 6 classes. With a Grade 3 class I might use addition and/or calculators .
you need a globe, a ball that's less than half the size of your globe and some yarn. Have a few students come up and show the class where they think the moon should be. then talk about the Equator and the distance to the moon Up north we use metric but if the equator is 25000 miles long and the average distance to the moon is about 239 000 miles how many times would I have to go around the Earth to equal a trip to the moon.

Multigrade's idea for fractions and oreo's is great but I'd wait until after the next New Moon so the students can watch the moon "get Bigger" in the evening sky.

Moon Distance/Diameter Ratio

There's an activity you might want to consider at http://www.exo.net/~pauld/exnet/spac...ing%20Tool.pdf. The similar triangles concept on which the estimation technique is based may be a little advanced for 3rd grade, but you can still do the calculations without yet knowing specifically why they work. When the concept is introduced later, they'll already have some experience with an application.

I once incorporated math when I taught the solar system. We had the kids figure out how much they would weigh on the moon and each planet. I used to have a worksheet that showed the kids how to do it. I had them use a calculator. I'll try to find teh worksheet for you.

Good idea. I forget everybody doesn't watch the moon like my class does. It's even part of our regular calendar time.

Moon Craters

We do a lab on moon craters. The kids drop different sized marbles into a pan of flour. We measure how the size of the space rock affects the size of the crater.
