The guiding question for this activity is,”What causes the pinwheel to spin?” In this activity, students decorate and put together pinwheels and will learn that pinwheels are designed to capture moving air and when the wind blows into the pinwheel, the blades spin. Students will also learn about windmill and wind turbine. Before beginning this activity, we recommend you read Chapters 9 and 10 which are in this book selection.
