Earth Materials...New Science

We have finally started our next science unit, Earth Materials. The kids have been anxiously waiting! They've had some experience with sand, pebbles and rocks in second grade so they are excited to see where we go with this one.

In order to set the mood, I dug out my rock collection. It has definitely stirred the interest in the classroom! If your kids have some they want to share, they certainly can...just make sure they have away of keeping track of their treasures.


We started by practicing some observation and recording skills, things all good scientists must do. We are using mock rocks, tape measures and hand lenses. We used some math skills, too, when we measured, diameter, circumference, and depth.
I was kind of chuckling to myself as I watched the kids. I was thinking about everything on their wishlists for Christmas and wondered.."Who knew they could be so excited by rocks...and these are 'mock rocks'?"
