Marble Ramps STEM Challenge Purpose: To practice group work and use problem solving skills to build a ramp that will slow down and stop a marble with a limited number of materials. Materials: • 2 sheets of newspaper • 1 meter masking tape • 1 marble • Scissors (for cutting, cannot be part of the ramp) • Ruler (for measuring, cannot be part of the ramp)

Criteria & Constraints Criteria • height-25 cm or taller • must carry a marble the entire length without being touched after it is first released • marble must change direction at least once • marble must stop at the end of the ramp Constraints • ruler and scissors can not be used as part of the ramp • ramp can not be taped to the table/desk • no extra supplies • limited time to complete this project (25 minutes)

Reflection Questions 1. What features of your design made your ramp strong? Weak? 2. What would you do differently if you had the opportunity to build this ramp again? Why? (You need to suggest at least one change. ) 3. How did working in a group make this activity easier to accomplish than working alone? 4. How did working in a group make this activity harder to accomplish than working alone? 5. What are three things you can do to make group work productive?
