WHAT IS ENERGY?

ENERGY is the ability to do work.

Let’s look at some examples to help better understand the forms of ENERGY and their relation to work.

Plants use the sun’s energy to grow and produce oxygen.

A radio uses energy to produce sound.

A mill uses energy to grind grain.

HUMANS use energy in everything they do.

Can you say things

in which we use energy?

Humans obtain resourcesfrom the Earth to do

these activities. ENERGY can be made

from energy RESOURCES.

WOOD ANIMALS

LIVING THINGS

WATER SOIL

NON-LIVING THINGS

FOOD GARBAGE

ALTERNATIVE RESOURCES

What do you think an alternative resource is?

Alternative resources are allrenewable but they do not need

regeneration.

SUN WIND WAVES

NON-RENEWABLE RESOURCES

What do you think is a non-renewable

resource?

Non-renewable energy resources cannot be replaced once they are used.

URANIUM

OIL: Petroleum and Diesel

COAL

NATURAL GAS

FOSSILFUELS

GAME: “THINK LINK”

EXAMPLES: The Sun and Wind are alternative resources.

Natural gas and coal are non-alternative resources.

THAT’S RIGHT THAT’S WRONG
