Balanced Students
Students investigate the relationships between weights, and construct a balanced first class lever. They formulate a general equation for the relationship explored in the experiment and perform calculations.
Curated OER
Work Made Easy
Second graders maneuver placement of the fulcrum on the lever to see how to lift weight most easily. They role-play as archaeologists with the task of lifting a heavy rock from the dig site. They write in science journals about what...
