We started learning how all rocks fall into three categories -igneous, sedimentary or metamorphic. Igneous rocks come from magma coming out of the earth and cooling over time. Sedimentary rocks come from sand and mud pressing together over time and hardening into rocks. Metamorphic rocks are rocks that have changed. The rock cycle was also introduced.
We are also watching our caterpillars in class. Three of them have changed into chrysalises in the classroom. We are measuring them and watching them grow and change (metamorphis).
Our experiment with plants is showing us that plants need food, water and air to grow. When one of those is missing, the plant is stressed. Students are not very happy with this experiment, they all want the plants to thrive.
