In this activity, students investigate pulleys. They build and test a range of pulley systems that increase in complexity, and then describe the way the pulleys change the magnitude and direction of the forces applied and the distance over which the load is moved. The activity includes a list of what is required, suggestions ...

This activity kit is about engaging students in thinking about wheels and axles. Activities are guided by the design thinking process, and scaffolds students to explore different types of pull-along toys, various ways of constructing them from a range of household and readily-available materials and investigate how wheels ...

This activity invites students to explore the phenomena of pendulums and investigate the question, 'What happens to the swing speed of your pendulum when you change one of the variables?' Students test one variable at a time to figure-out the effect of length, weight, and release point on how long it takes the pendulum ...

In this activity, students investigate the motion of falling objects, with and without a parachute. They explore whether different objects fall at different speeds and predict how different materials for making parachutes will perform. They then design, make and test their own toy parachutes. The activity includes a list ...

This activity kit encourages students to design and construct a simple water wheel model that turns by the flow of water. Activities are guided by the design thinking process, and scaffolds students to research the applications of various simple machines, and the combinations of simple machines they might use to build a ...
