Student Exploration: Energy Conversions

Vocabulary: chemical energy, electrical current, energy, fossil fuel, global warming, gravitational

potential energy, hydroelectricity, kinetic energy, light, nonrenewable resource, nuclear energy,

renewable resource, sound, thermal energy

Prior Knowledge Questions (Do these BEFORE using the Gizmo.)

1.What are sources of electricity? List as many as you can. The three major categories of

energy for electricity generation are fossil fuels (coal, natural gas, and petroleum), nuclear

energy, and renewable energy sources. Most electricity is generated with steam turbines

using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy

2.Where do people and other animals get energy to move around? Food

3. Where do plants get energy to live and grow? The sun

Gizmo Warm-up

In the Energy Conversions Gizmo, be sure Information

mode is selected. Click on each of the different items in the

scene and read about each one.

1.Which object converts sunlight into sugars?

Corn

2.Which object converts wind power to electricity?

Wind Turbine

3.Which object converts light to electricity? Solar Panels

4.Which object converts electricity to light? Light Bulbs

Which object converts light to electricity to light?

Solar cells convert sunlight to electricity. Sunlight causes wind and rain, powering wind turbines and hydroelectricity.

What is the name of the device that converts light into electricity?

A photovoltaic cell is a semiconductor device that converts light energy directly to electrical energy.

What can electricity be converted into?

Electrical energy can be converted to mechanical energy, light energy, heat energy, etc. Chemical energy can be converted to electrical energy. Thermal energy can be converted to heat energy. Mechanical energy can be converted to electrical energy, potential energy, etc.

What is an example of electrical energy to light energy?

A lightbulb is connected to an outlet that has a source of electricity. The electrical energy is converted into light energy to allow the bulb to glow.
