A fourth-grade lesson on simple machines integrates performance assessment tasks.
This very interesting article describes a lesson plan by a fourth grade teacher on simple machines. First the students learned about simple machines and how they are used. They also did a scavenger hunt at school and home to find simple machines. Then they were given one of four performance tasks to do in groups. They came up with some very amazing ideas that indicated they understood how simple machines work.
