Week of February 9th
This week in science every group made presentations on different characteristics of rocks. Some of the characteristics were fracture, cleavage, shine, streak, taste, and etc. After all the presentations were over we started a lab. For the lab, six different rocks were given to each group. Each group has to find the correct characteristics of all the rocks. The first group to find it gets a free quiz grade!!
