Second graders were immersed in both chemistry and physics in our first unit, “States of Matter.” They investigated the properties of solids, liquids, and gases while also learning that matter is anything that has mass and volume. They explored the difference between chemical and physical changes, and we ended the unit on a high (and messy) note, creating that favorite of all non-Newtonian fluids, Oobleck. We have now moved on to one of the most beloved units in all of Lower School science: “Spacetime!” Second graders don’t just memorize the names of the planets and their characteristics - we go deep! To get started, we discuss how space and time are intrinsically linked, and how this idea made Einstein so famous. In any study of spacetime, a concrete sense of huge numbers is helpful. Ask your child if they can remember what they learned in science about the difference between a million, a billion, and a trillion. Astronomy and math are inseparable, and an interest in one can often inspire interest in the other.
