How to Build a Toy Car - Science Project

This video tutorial guides viewers on building a toy car, detailing the main components: wheels, axles, chassis, and power source. It explores various power options like ramps, balloons, rubber bands, and sails. The video provides materials and methods for constructing the chassis and wheels, and techniques for building axles. It also covers how to build different types of cars, such as balloon, rubber band, and sailboat cars. Finally, it discusses connecting parts and turning the project into a science or engineering experiment, emphasizing the importance of iteration and variable selection.

What is the first step in designing your toy car?

• Selecting the color of the car

• Determining the car's weight

• Deciding on the power source

• Choosing the type of wheels

Which material can be used to create the chassis of the toy car?

• Cotton fabric

• Glass jar

• Metal sheet

• Plastic bottle

What can be used to increase the friction of the wheels?

• Reducing the weight of the car

• Using larger wheels

• Wrapping a rubber band around the wheel's edge

• Adding oil to the wheels

How can you propel a balloon-powered car forward?

• By pushing it manually

• By inflating the balloon and releasing the air

• By using a motor

• By adding weights to the car

In a science project, what is an example of a dependent variable?

• Color of the car

• Material of the chassis

• Distance traveled by the car

• Type of wheels used
