We finally had an opportunity to look at the rocks we found in a previous activity. Each group had 12 specimens to explore and describe. One by one, students added the rocks to their "journals".
 | I was interested in seeing them work with their teams, as well as how thoroughly they observe things (They still need a guiding hand with their writing and reporting.). The groups were talkative, but they were able to get quite a bit of information onto paper.  |
| Along the way, we curiously dropped a piece of pumice into a cup of water and discovered that this rock actually floats on the water...at least until it absorbs enough water to change its density and cause it to sink. We will find the differences between rocks and minerals, next week, and I suspect students will enjoy the tests we perform on the minerals even more.  |  |
