In today's class, the students finished up the assignments I had the substitute hand out while I was on the Washington DC trip. I also gave the students a matter study guide to help prepare them for the test. The students will have a test over matter on Tuesday that will have 25 multiple choice questions and a bonus. The students can make their own study guide from the one I gave them and can use it on the test or just study the study guide to get them ready for the test. On Wednesday the students will start an unit on energy. Here is a copy of the study guide for the test on matter tomorrow.
