Problem solving is at the heart of this understanding. Through experiments, students observe friction, push and pull and make preditions about how objects will move. Students make 3-D structures of land formations and the layers of the earth. They experiment with rock samples to identify the rock properties. Second graders learn about opportunity cost, scarcity, supply and demand through role playing in a classroom economy.
Second graders observe and chart temperatures, precipitation and cloud formations.
Emergency procedures are practiced for severe weather conditions. Using the animal excursion program, students learn first hand about the life cycles of different animals.
