Teachers, save “STEM Rolling over” to assign it to your class.

1. Collect some items that roll. Try to find objects made of different materials like glass, plastic, metal, card 2. Pick 3 different surfaces to test them on. For example, a tiled floor, a carpet, your bed. 3. Before you start, think about the following questions and make some predictions (informed guesses): * Which shape will roll the furthest? * On which surface will the items roll the smoothest? * Will they all roll in a straight line? * What other things do you think might happen? 4. Test each one on all 3 surfaces and make sure to write down what happened each time. 5. When you are done describe your learning in writing. Write about.... * The shape that rolled the furthest (say why you think that is) * The surface on which the items rolled the smoothest (say what it is about the surface that made things roll well) * Using describing words, help the reader to visualise how some objects rolled in different ways.
