Topic: Forces & Motion

•  Identify the action of forces by investigating a variety of everyday situations.

•  Recognize that a force is a push or a pull.

•  Identify attraction/repulsion forces between the ends of two bar magnets.

•  Identify through observation the forces that cause things to move or stop.

•  Identify through observation the forces that change speed or direction of motion (e.g. friction).

•  Design and build simple machines that slow down, increase speed, or purposefully direct the transfer of energy (e.g. containers to slow down the rate at which ice melts, materials that act as sound absorbers, electric circuits aimed at performing functions, mirrors to direct light, devices powered by rubber bands, and solar cookers).

•  Predict how simple machines such as household appliances work, then dismantle to identify the sequence of energy transfers.

Learning Activities:

1. Simple Machines. Six types of simple machines. Students create their own machine that will perform a task of some sort - like picking up another object and uses some of the six simple machine ideas.
2. Force: What is it?
3. Weight & Gravity. Make a scale to measure the mass of things.
4. Gravity. Which object will fall faster?
5. Friction: What is it?
6. Levers - different types and solving problems with levers.
7. Pulleys
8. Egg container challenge. Design a container to protect an egg dropped from a height.
