107 ISSUE/PROBLEM (society issue, issue that is seen relevant from pupils’ perspective, issue linked to some nature phenomenon or phenomenon from pupils’ everyday life) How do forces work in everyday life? INVESTIGATIONAL STAGE DESCRIPTION OF THE ACTIVITY This activity is about applying Newton’s Laws of Motion to a salad spinner art. Students learn about forces in a fun, aesthetical way! TASKS STEP 1: Students in groups of 2/or individually gather the material they will use. STEP 2: Students place the salad spinner on a flat surface and put a paper plate on the bottom of it. Alternatively, they can cut a piece of paper to fit in the bottom. STEP 3: They add drips and drops of paint all around the surface of the paper plate. STEP 4: When they are satisfied with the amount of paint, they close up the salad spinner tightly and get it spinning! STEP 5: Students are then asked to explain the outcome and the reasons why this happens. Extra step for advanced students: The teacher can ask: What happens if they thin the paint first with a bit of water? Does changing the viscosity or thickness of the paint have a different effect?
