• No prior knowledge required

Activities

1. Activity 1: Pendulum Experiment

   Set up a simple pendulum using a string and a weight (e.g., a small object like a paperclip or a washer). Measure the length of the string and the time it takes for the pendulum to complete one full swing. Repeat the experiment with different lengths of string and record your observations. Analyze the relationship between the length of the string and the time it takes for the pendulum to swing. What patterns do you notice?

2. Activity 2: Balloon Rocket

   Create a balloon rocket by attaching a string to two fixed points (e.g., two chairs) and tying a balloon to the string. Blow up the balloon and release it, observing the motion of the balloon rocket. Measure the distance it travels and record your findings. Experiment with different balloon sizes and string lengths to see how they affect the distance traveled. Can you explain the physics behind the balloon rocket's motion?

3. Activity 3: Egg Drop Challenge

   Design and build a contraption that can protect an egg from breaking when dropped from a certain height. Use materials such as straws, tape, and paper to create a protective structure around the egg. Test your contraption by dropping it from different heights and see if the egg remains intact. What design features help absorb the impact and protect the egg? How can you improve your contraption?

Talking Points

• Gravity: "Gravity is a force that pulls objects towards each other. It is what keeps us grounded on Earth and affects the motion of everything around us."
• Inertia: "Inertia is the tendency of an object to resist changes in its motion. Objects at rest want to stay at rest, and objects in motion want to keep moving at a constant speed and direction unless acted upon by an external force."
• Friction: "Friction is a force that opposes motion when two surfaces come into contact with each other. It can slow down or stop the motion of objects."
• Momentum: "Momentum is a property of moving objects. It depends on both the mass and velocity of an object. The greater the mass and velocity, the greater the momentum."
• Newton's Laws of Motion: "Newton's laws describe how forces affect the motion of objects. The first law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an external force. The second law relates force, mass, and acceleration. The third law states that for every action, there is an equal and opposite reaction."
