- Paper Airplane Challenge: Explore the principles of aerodynamics by designing and testing different paper airplanes. Measure their flight distance and discuss how factors like wing shape and weight affect their performance.
- Pencil Conductivity Test: Investigate the conductivity of different materials using a pencil, paper, and a battery. Draw circuits on paper and observe which materials conduct electricity, sparking conversations about electrical conductivity.
- Straw Rocket Launcher: Construct a simple rocket launcher using a drinking straw, a balloon, and some tape. Experiment with different balloon sizes and launch angles to explore how forces and angles affect projectile motion.
- Rubber Band Helicopter: Build a small helicopter using a rubber band, a craft stick, and a paper clip. Investigate how different blade designs and rubber band tensions affect flight stability and lift.
- Cartesian Diver: Create a diver using a plastic pipette or an eyedropper and a bottle filled with water. Explore buoyancy and pressure as you manipulate the density of the diver to make it sink or float.
- Magnetic Maze: Design a maze using paper and magnets. Test the magnetic forces and learn about magnetic fields, attraction, and repulsion by maneuvering a magnet through the maze.
- Balloon Rocket Car: Construct a car using a balloon, a drinking straw, and four bottle caps. Explore the principles of Newton’s third law of motion and propulsion by releasing air from the balloon to move the car forward.
- Paper Clip Compass: Magnetize a paper clip by rubbing it against a magnet. Float the paper clip on water and observe how it aligns with the Earth’s magnetic field, introducing the concept of magnetism and compass navigation.
- Marshmallow Catapult: Build a simple catapult using a plastic spoon, rubber bands, and popsicle sticks. Experiment with different arm lengths and projectile weights to explore potential and kinetic energy.
- Simple Circuit Quiz Game: Create a quiz game using paper, foil, LEDs, and batteries. Build simple circuits with questions and answers, allowing players to complete the circuit and light up the correct answer.
