As I have mentioned before, I try to do a simple science experiment with the kids on Fridays. Our lesson today was learning about evaporation. Here are the steps. You can have your child draw pictures to go with each step if you want and then make a little book out of it.
1. boil some hot water
2. mix in some salt
3. leave the salt water in the pan
4. check the pan the next day
5. see how many days it takes for the water to evaporate.
6. see what is left after the water has evaporated.
You can get a cute download for this at www.homeschoolshare.com under the FIAR resources. Correlates with the book How to Make an Apple Pie and See the World.
