Science Review "Egg Racers"

A rubber band as an "engine" to help your egg racer move faster is an example of ____________________?

• making the egg racer much lighter so it will have more energy of motion.

• making the egg racer much heavier so it will have more energy of motion.

• increasing the egg racer's height so it will have more energy of motion.

• a propulsion mechanism so it will have more energy of motion.

• cheating!!

Which is NOT true when the energy of a moving object changes during a collision?

• Energy can be transferred into other forms (light, sound, heat)

• Energy can change the color of the object in the collision.

• Energy can be absorbed (like the crumple zones of a car)

• Energy can change directions

What is one way to make a car safer so the egg is not damaged in a collision?

• Put on square wheels so it can't roll too fast.

• Make sure there is no roof so the egg will fly out in a collision.

• Make the car parts as strong as possible so it will NOT crumple in a collision.

• Add cushion to the egg like bubble wrap or cotton balls.

What is another way to make my car safer, so my egg is not damaged during a collision?

• Add an airbag to cushion the egg.

• Put a helmet onto the Egg's head.

• Put a propulsion device on the car to make it go slower.

• Make the car as light as possible.

What is yet another way to make my car safer, so my egg is not damaged during a collision?

• Use thicker cardboard so the car won't break in a collision.

• Put more wheels on the car.

• Put a seatbelt (safety harness) on your egg

• Make sure your egg has a thicker shell.

What is the definition of "sound" energy?

• the action or process of moving

• the force that pulls objects down to Earth
