FORMS OF ENERGY4th Grade Science

ENERGY Energy is the ability to work or cause

change. Work means moving an object form one

place to another. Energy makes things happen. It can make matter move or change.

MECHANICAL ENERGY Mechanical energy is the energy of

moving objects. Examples: moving your body, riding a

bike, gears moving in machines

LIGHT Light is energy that we can see. Light energy comes from the sun. The sun, burning candle, lightbulb, and

match give of energy in the form of light.

HEAT Heat is energy moving from matter with

a higher temperature to matter with a lower temperature.

Heat also travels to Earth from the sun. Many things give off heat including

wood burning, your body, and light bulbs.

Most things that give off heat also give off light.

SOUND Sound is energy that we can hear. Sound is made by objects vibrating. Sound energy moves through the air in

waves. When sound reaches your ears, the air

in your ear vibrates. This makes your parts of your ear vibrate causing you to hear the sound.

VIBRATE Vibrate means to move back and forth

very fast. All the sounds we hear are from

vibrations.

CHEMICAL ENERGY Chemical energy is energy that is stored

in a material. We use a lot of chemical energy by

burning things such as coal, oil, and wood.

Our body burns the chemical energy store in food to keep us alive.

Batteries also store chemical energy.

ELECTRICAL ENERGY Electrical energy is the energy of

moving electric charges. Electrical energy moves from power

plants through wires to our homes and schools.

Electrical energy runs things such as lamps, refrigerators, computers, and toasters.

Lightning is also a form of electrical energy.

ENERGY TRANSFORMATIONS Energy transformations are the changes

from one form of energy to another. Electrical energy can be changed into

heat, light, sound, and mechanical energy.

Chemical energy can be changed into light, heat, mechanical, and electrical energy.

ENERGY POWERPOINT This powerpoint was created using

Microsoft Office 2007. All designs, slides, pictures, fonts, and clipart where gathered from Microsoft Office 2007.

This powerpoint was created to go along with Lesson 18 of Tennessee TCAP Coach book, but could be used for any 4th grade lesson on energy.
