Intended Learning Outcomes:
Step 1. Pass out supplies to each group's runner. Have each runner fill the 2 L bottle halfway with water.
Step 2. Explain to the students that their challenge is to create a simple machine that will move the water bottle at least 12 inches. Students are not allowed to directly touch the bottle when moving it. They may use the rope, the yardstick and blocks to accomplish the task. Have them come up with as many possible solutions as they can in 30 minutes.
Step 3. The timekeeper should keep the group moving and aware of the time. The recorder should record the group's observations and write down any problems that were encountered. The recorder should also record any solutions that the group comes up with. Each group should draw pictures of their solutions.
Step 4. As the group works together, have them consider some questions that you post on the board:
Step 6. Ask students to form conclusions that they could state from these activities. Did they discover that they could use a pulley or a lever (simple machines) to lift the bottle? Did anyone create something more complex? Have students record their experiments and observations in their science journals.
Step 7: In their science journals, ask students to explain why objects at rest will not move unless a force is applied to them. Ask them to compare the forces of pushing and pulling.
Instruct students to show that objects at rest will not move unless a force is applied to them.
Instruct students to compare the forces of pushing and pulling.
