What are some good science topics for 2nd grader?

Second-grade science tends to focus on learning about the world around us through observation and experimentation, including concepts like the seasons, the cycle of life and the human body. Second graders usually also learn about matter, insects, electricity, earth and space.

A good way to teach a second grader about earth and space is by focusing on movement and locations of stars, and the properties of suns, moons, and planets. Second graders typically learn about electricity by learning how batteries work. To teach a second grader about the human body, instructors usually focus on the skeletal, muscular, digestive and nervous systems, as well as how to properly care for the body.
