Before we began, we made hypotheses - is there acid rain in our town? Most of the students, sadly, were convinced that our rain is harmful. After they labeled and filled their three cups, they inserted the pH papers and waited patiently for the colors to change. Once they did, they used the guide to check the numbers.
Yesterday we did a jigsaw activity to learn about a few alternatives to fossil fuels. Afterwards, the students wrote letters to their state senator or congressperson to encourage him or her to support legislation that encourages the use of fossil fuels. Most of the letters turned out really well after we brainstormed ideas of what we could tell them. They wrote with a lot of passion and knowledge of the alternatives!
|Here is a little sampling of our letters. As soon as I get them all, I'm sending them away! Hopefully they will write back to us. :)|
