- A small, lightweight car (such as a toy car or a matchbox car)
- A motor (such as a small electric motor or a rubber band)
- A battery (such as a AA battery or a 9-volt battery)
- A switch (such as a toggle switch or a push button)
- Some wheels (such as plastic wheels or wooden wheels)
- An axle (such as a metal rod or a wooden dowel)
- Some glue
- Some tape
- An egg
Instructions:
1. Attach the motor to the car. If you are using an electric motor, you will need to solder the wires from the motor to the battery. If you are using a rubber band, you will need to attach the rubber band to the motor and the axle.
2. Attach the battery to the car. If you are using a AA battery, you will need to insert it into the battery compartment of the car. If you are using a 9-volt battery, you will need to attach it to the car with some tape.
3. Attach the switch to the car. If you are using a toggle switch, you will need to drill a hole in the car and insert the switch. If you are using a push button, you will need to glue the push button to the car.
4. Attach the wheels to the car. If you are using plastic wheels, you will need to push them onto the axle. If you are using wooden wheels, you will need to glue them to the axle.
5. Test the car. Turn on the switch and see if the car moves. If the car does not move, check the connections between the motor, the battery, and the switch.
6. Place the egg on the car. Make sure that the egg is secure and will not fall off.
7. Turn on the switch and let the car go. The car should travel at least three meters before stopping.
Congratulations! You have made a self-propelled car that can carry an egg at least three meters.
