What simple machine makes it easier to lift heavy objects?
The Pulley!
What is a chain reaction?
A series of events triggered by the initial action.
22 + 12 = ?
34
The planet that we live on
Earth
This type of energy is stored and waiting to be used.
Potential energy
What is pneumatics?
Using air pressure to create movement.
How does height affect the potential energy of an object?
As height increases, potential energy also increases.
72 - 20 = ?
52
True or false: Penguins can fly
False
The ability to use energy to move something
Work
What can the kinetic energy from a wind turbine be used for?
Lifting objects, generating electricity, pumping water, grinding rice
How did your rubber band car convert potential energy into kinetic energy?
When you pull on the rubber band, you store potential energy and as you let go it is converted into kinetic energy - making your car move!
The name of a shape that has 8 equal sizes
Octagon
Which doesn't belong in this group: dolphin, shark, dog, fish, whale?
Dog
This word describes how fast you are using energy.
Power
How does Newton’s third law help explain why the last marble moves in a Newton’s Cradle?
The action of one marble hitting causes an equal and opposite reaction in the last marble.
Why did the marbles gain speed when going downhill on our paper rollercoaster but slow down in other parts?
As the marble rolls downhill, its potential energy (energy due to its height) is converted into kinetic energy, causing it to speed up.
The marble slows down going uphill because kinetic energy is converted back into potential energy.
The next number in the sequence: 3, 6, 9, 12, __?
15
The gas that living creatures need to breathe
Oxygen
