Rocks and Soil Unit

For the past three weeks we have been working on our rocks and soil unit. First, we looked at different rocks and saw that they can be classified based on size, color, shape, and texture. We watched a movie, read several books, and completed our science workbooks. Students took the information that they learned to make a circle map.

Next we moved onto soil. Students observed different kinds of soil. We discussed how each soil holds water. We found that the best kind of soil for growing plants is humus. We planted a seed in humus, sand and clay. ( We are still watching these as they sit by the window).

Our last part of the unit involved making a flip book about the different soil layers. Last we made a soil layer snack. We used marshmallows for the bedrock layer, cheerios for the subsoil layer, coco krispies for the topsoil and humus. We added mini m&ms for the bugs and a gummy worm to top it off. Students were able to identify the layers from their flip book with the ones in their snack. What a yummy way to finish off rocks and soil!!
