Catapult Science Project
Objective
The make a Catapult Science Project using craft sticks
Materials
- Eight craft sticks (popsicle sticks)
- Four or five strong rubber bands
- Glue
- Cap of plastic bottle to hold the cotton ball
- Cotton ball
Catapult Science Project Preparation
- When using a cotton ball, the basic catapult suggested in this project is completely safe. To avoid harming someone or the objects around you, make sure any items you throw are soft and light.
- Six craft sticks should be stacked on top of each other. Wrap rubber bands around both ends of the stack to keep the sticks together. As indicated in the following step, you will anchor the launching stick for this stack.
- To attach the launching stick, take a stick and wrap it vertically around the middle of the stack you have made, forming a cross shape. One or two rubber bands crossed in an X on the sticks might be used for this. The sticks will be absolutely vertical if you cross them like mentioned above.
- Attach the base by using a rubber band to attach a stick to one end of the launching stick. The launching stick would fall on top of the base if it weren’t for the stacks of sticks in the middle. Now, between the launching stick and the stack of sticks between the bases, construct a V shape.
- Place your catapult on its base, find the sticking end of the launching stick, and glue the cap to the bottle, forming a little cup to contain the missile.
- Now let the glue dry.
Procedure
- Place your Catapult Science Project in a large open location with flat surfaces, such as a table or a hard floor.
- Place a cotton ball in the launching cup, gently lower it, then release it.
- Make a test: Place your cotton ball in the cup, push it down, then release it and inspect it. To complete your observations, you may need to repeat the experiment numerous times.
- See what happens if you move a stack of six sticks closer or farther away from the launch cup. When the missile is in the air, this will adjust the location of the firing stick.
- Make several catapults and compete with your pals in a game. As the objective, use the last bottle cap. Place the catapults in a circle 60 cm away from the cup and compete to see who can score the most goals.
Observations and results
When you bend your stick, you add energy to your launching stick. This energy is released and turned into kinetic energy when you let go. The majority of this energy is turned into missiles that are sent into the air. It takes more work than you think to push the stick down deeper. It’s possible that you’ll feel compelled to strive even harder to bend the stick. When you lean further, more elastic potential energy is stored in the rod, and when you let go, all of this potential energy is converted into kinetic energy, causing the missile to fly faster in the air. The rocket from your catapult is likely to fly high and far.
The launch stick is delayed by moving a stack of six sticks closer to the launching cup. As a result, a missile strikes the front instead of the back. When you push your six sticks in the other way, the launching stick and the base form a large angle. It assists you in propelling the projectile ahead.
