One STEM activity for November could be creating a wind-powered vehicle.
Materials needed: - Small toy car or vehicle - Balloon - Drinking straw - Tape - Scissors - String
Instructions: 1. Start by cutting a small hole in the back of the toy car, big enough for the drinking straw to fit through. 2. Insert the drinking straw into the hole, making sure it is secure. 3. Blow up the balloon and pinch the end to keep the air inside. 4. Attach the balloon to the end of the drinking straw using tape, ensuring it is tightly sealed. 5. Tie a string to the front of the toy car, creating a handle for pulling. 6. Find an open space with a smooth surface, such as a hallway or outdoor area. 7. Hold onto the string handle and release the air from the balloon, allowing it to propel the car forward. 8. Observe and measure the distance the car travels. 9. Repeat the experiment with different sizes of balloons or by varying the amount of air blown into the balloon. 10. Discuss and analyze the results, noting the impact of air pressure on the car’s movement.
This activity allows students to explore the concept of air pressure and its effect on motion. They can also experiment with different variables to see how it affects the car’s speed and distance traveled.
