Today, we made it rain INSIDE OUR CLASSROOM! We used a crock pot to be the sun. The sun evaporates water from oceans, lakes, rivers, ponds, puddles, and the soil. So, Mrs. Freeman put water in the crock pot and heated it up to evaporate it. Then, Mrs. Freeman passed a pan around for us to inspect and make sure everyone was satisfied that there were no holes. Next, she put ice in the pan to represent the upper atmosphere, where it is very cold. She held the pan with ice in it over the crock pot. The water vapor that was evaporating from the crock pot condensed on the bottom of the pan. That means it turned from a gas back into a liquid. We could see the drops, and we knew they must be from the water vapor, since there were no holes in the pan! When the drops got too big, they dripped off the pan - it was raining! Mrs. Freeman dripped a rain drop on each one of us! And that's how we made it rain.
This blog is maintained as a collaboration between all students and myself. Each week, one student has the classroom job of "Blogger". That student helps decide subjects for our posts, as well as writing one blog post about him/herself.
