Gr 6 Electricity Practice Review Test

Electricity is a form of?

• Energy

• Matter

• Sound

• Light

Energy use impacts the environment by:

• Increasing pollution and greenhouse gas emissions

• Reducing natural resource consumption

• Enhancing biodiversity

• Improving air and water quality

Label the type of energy: Energy that moves an object.

• Radiant Energy

• Chemical Energy

• Mechanical Energy

• Thermal Energy

• Nuclear Energy

Label the type of energy: Energy from the movement of particles. Heat is created when particles move quickly.

• Radiant Energy

• Chemical Energy

• Mechanical Energy

• Thermal Energy

• Nuclear Energy

Label the type of energy: Energy that travels in waves, such as visible light or x-rays.

• Radiant Energy

• Chemical Energy

• Mechanical Energy

• Thermal Energy

• Nuclear Energy

Label the type of energy: Energy stored in bonds of atoms and molecules, often released when heated.

• Radiant Energy

• Chemical Energy

• Mechanical Energy

• Thermal Energy

• Nuclear Energy

Electricity is not simply “created” by outlets, plugs, or wires because:

• it is generated at power plants and transmitted through the grid.

• outlets, plugs, and wires have their own power sources.

• electricity is a natural resource that is mined.

• it is created by batteries in the outlets.

What is the input and output energy for the Electric guitar? The energy may be transformed into more than one type of energy.

• Input: Electrical energy, Output: Mechanical energy

• Input: Chemical energy, Output: Electrical energy

• Input: Nuclear energy, Output: Thermal energy

What is the input and output energy for the Solar panel? The energy may be transformed into more than one type of energy.

• Input: Solar energy, Output: Electrical energy

• Input: Electrical energy, Output: Solar energy

• Input: Chemical energy, Output: Electrical energy

What is the input and output energy for the Hydropower dam?

• potential energy (from the height of the water) being converted into mechanical energy (as the water turns turbines), which is then converted into electrical energy.

• kinetic energy (from the flow of the water) being converted into thermal energy, which is then converted into sound energy.

• chemical energy (from the water composition) being converted into nuclear energy, which is then converted into light energy.

• solar energy (from sunlight) being converted into wind energy, which is then converted into magnetic energy.
