Activity Description: Challenge the youth to design and build a device that catches simulated rain and funnels it into a small container.
Items Needed:
- Cardboard, foam board, or a plastic container
- Straws, skewers, or pipe cleaners
- Tape or glue
- Aluminum foil, plastic wrap, or cardboard
- Scissors
- Small container or bowl
- Spray bottle or running water from a sink faucet
Instructions (Estimated Total Time: 25–35 min):
Note: Provide only the challenge and supplies to the youth so they can create their own designs, using the steps below merely as a guide to offer hints if they get stuck.
- Build the frame. (10 min)
- Use a base material and structural items to create a framework that directs water.
- Create the water collector. (5–10 min)
- Design a surface using foil, plastic wrap, or cardboard to capture water and channel it downward.
- Use tape or glue to hold everything in place and make their structure sturdy.
- Test the device. (2–5 min)
- Use the spray bottle to mist water above the device to simulate rain and observe how well it collects water or run a thin stream of water onto the device in the sink.
- (Optional) Measure how much water is in the water bottle before and after the test. Then measure how much water was collected to see how efficient the device is.
- (Optional) Adjust and improve. (5 min)
- Encourage them to modify their structure and materials as needed to collect water more efficiently.
