Use construction paper, a pencil and a thumbtack to demonstrate how wheels spin.
When wheels move, they can generate energy. The movement of wheels depends on what they are made of and what forces are acting on them. By designing and creating simple pinwheels, your students can explore these variables.
Before you get into making pinwheels, get your students to start brainstorming. You can have them call out different things that spin while you list them on the board. As a group, talk about what makes things spin.
If the pinwheels aren’t spinning very well, try the following:
Use different materials to create more pinwheels. As a group, talk about:
You can use the pinwheel activity to introduce and explore various science topics including:
This activity provides an opportunity for you to assess the following skills in students:
Build a solar updraft tower to see radiation and convection at work.
Watch a slideshow and play a matching game about thermal energy at home.
Learn how to use data to make good scientific decisions.
