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.
