There are two main categories of energy: kinetic energy and potential energy. Kinetic energy is the energy of motion. A car driving down the road has kinetic energy. What type of energy does a boulder sitting on a cliff edge have?

Saturn is also a gas giant, known for its:

• a) Rings

• b) Great Red Spot (storm) on Jupiter

• c) Volcanic activity

• d) Thick atmosphere

When light bends as it passes from one medium to another (like air to water), it is called:

• a) Reflection

• b) Refraction

• c) Absorption

• d) Transmission

Energy is the ability to do work. Energy can be transferred from one object to another in many ways. What is NOT a way to transfer energy?

• a) By pushing or pulling an object

• b) By heating an object

• c) By sound waves traveling through the air

• d) By magic

Venus is the:

• a) Hottest planet

• b) Coldest planet

• c) Most Earth-like planet

• d) Gas giant

The Earth can be divided into several main layers. The outermost layer is the:

• a) Inner core

• b) Outer core

• c) Mantle

• d) Crust

Thermal energy, or heat, can be transferred in three ways: conduction, convection, and radiation. Conduction is the transfer of heat through direct contact. Which of these objects would be a good conductor of heat?

• a) Wood

• b) Metal

• c) Plastic

• d) Cloth

A resistor is a component that resists the flow of electricity. Resistors are used to

• a) Control the current in a circuit.

• b) Flow the electrical current

• c) Empower the circuit

• d) Light a bulb

A complete circuit allows electricity to flow. An incomplete circuit prevents electricity from flowing. What happens to the circuit when a light switch is turned off?

• a) The voltage increases

• b) The current decreases

• c) The circuit becomes complete

• d) The circuit becomes incomplete

When light hits an object, it can be reflected, absorbed, or transmitted. What does it mean when light is reflected?

• a) The light passes through the object.

• b) The light bounces off the object.

• c) The light is taken in by the object.

• d) The light changes color.
