Balloon Rocket Car Science Project

Additional information newton s third law of motion law of reciprocal actions states. In this model your nozzle is the size of one drinking straw.

Balloon Car Lesson Plan

Watch the balloon rocket science experiment step by step instructions.

Balloon rocket car science project. Look at the balloon rocket car experiment and notice that as soon as you let go of your grip the air escapes through the straw nozzle propelling the car across the flat surface in the opposite direction because the balloon air is under pressure. Covering the straw opening keeps this high pressure air trapped. Watch our video to see a balloon rocket in action.

The principles of rocketry apply to more than flying rockets with this project you can make a rocket car that is powered by pressurized gas air in a balloon. To demonstrate newton s third law of motion by constructing a balloon powered rocket car. Science project to make your rocket go faster you can increase the size of the nozzle where the air escapes the balloon.

A balloon powered car consists of three main parts. The body of the car piece of cardboard or plastic bottle in figure 1. It allows children showcase their engineering skills by building the car and also enhances their knowledge by presenting an opportunity to apply laws of classical physics.

Kids science projects. Whenever a particle a exerts a force on another particle b b simultaneously exerts a force on a with the same magnitude in the opposite direction. Thrust can be explained by newton s third law of motion.

Here the air escaping the balloon is the action while the car moving. Newton s third law states that for every action there is an. In this project you will be challenged to build and test your own balloon powered car.

When the balloon is blown up the air inside is pushing on the skin to keep it inflated. Once the straw nozzle is uncovered the balloon s stretched skin pushes the air out and creates a thrust. This thrust force propels and makes the car accelerate forward.

Balloon rocket science experiment video tutorial. How does the science experiment work. A balloon car is an innovative science fair idea.

By involving in this activity they also garner a lot of fun as it enables them to build their own balloon powered rockets something that is no less than an exciting toy. The balloon flies across the string because of air and thrust. Balloon powered cars like the ones in figure 1 are fun to build and even more fun to play with.

The balloon rocket is a great science experiment for kids to grasp the concept of force and energy.
