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.
WHAT IS A NATURAL RESOURCE?
CLASSIFICATION
A natural resource is a material that comes from the Earth.
• RENEWABLE RESOURCES
• ALTERNATIVE RESOURCES
• NON-RENEWABLE RESOURCES
RENEWABLE RESOURCES
What do you think a renewable
resource is?
Renewable resources regenerate or can be replaced in a short timeperiod.
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
Let’s investigate each different
resource…
