Emma wanted to post a picture of her science homework tonight. She made some great discoveries about the properties of heat. (It rises!) It was a lot of fun and she even enjoyed writing about her findings. Thank Heavens for good teachers who aren't slaves to worksheets!

Silly rabbit, heat is for kids. I miss those fun science projects.
Looks like an interesting experiment, Emma. Maybe yiu could do it for Grandpa and me the next time we come to your house. Love you--Grandma Ward
Science is way cool! especially when you get to live it rather than read about it! I've learned things about the Maine coast, Maine culture, Maine economy, etc that would have slid right over the top of my head had I read it in a book!
Did you get to drink your experiement after it was done? Which was better the hot or the cold? Looks like fun. Thanks for sharing!
Emma,
This looks like a fun experiment. Get your mom to let you see what happens when you freeze water. Hint: don't fill the bottle all the way to the top. Let me know what you find.

Emma -
you are so smart. good for you! when you are ready for another science experiment you can ask Joe how he set almost 40 lbs. of books on top of four eggs without breaking them. He won first prize in the school science fair with that one ....!
How did Joe do that???
Joe placed 4 eggs (on their broad sides, not ends), then a rag, then gently placed one encyclopedia after another on top of the eggs.
the eggs don't break until you get a lot of weight on them because the arch is one of the strongest shapes in nature. engineers use it in tunnels for metro stations, etc. (his winning experiment had pictures of some of the ways engineers and architects use arches along with pictures of the books on top of the eggs). Joe's favorite part of the experiment was when that last encyclopedia went gently down and the eggs went crack. he laughed and laughed and we did it again and again. after each round we weighed the books - it was pretty consistent.
It is a fun (and realtively cheap & easy compared to some) science fair project. I forget why eggs crack so easily when you smack them (as opposed to putting weight on them), but there is a reason.
