Emma brought in a box of labeled rocks, lent to her by a co-worker of her mother's. We examined two of the igneous rocks this morning, pumice and granite. Students noticed a big difference in the way the two rocks felt when we passed them around. The pumice was very light. We talked about why that might be and came to the conclusion that it had a lot of air pockets. Amy commented that it was like a sponge. We ended the day by erupting a volcano (baking soda and vinegar) and observing all of the air bubbles. We then imagined what it would be like if this concoction was really lava and quickly hardened. We will continue exploring rocks this through the week.

This week I introduced the letters u and e. I put a sheet showing the formations for s, d, u, and e in your child's red folder. We have now been introduced to all of the vowels and nine consonants. We are able to make quite a few words! In math we have begun a unit on patterns. I also included a note about this in your child's folder.
