Heat moves from warm places to cold places. Heat moves from
warm things to cold things. Heat can come from different things. Heat comes
from the light of the Sun.
Light from the Sun heats water and land.
Rub things together. This makes heat too. Moving also makes heat. Jump up and down.
How does your body feel?
Energy
The Sun gives light. Light is a kind of energy. Energy can
change things. Energy from the Sun can change the temperature. More light makes things warmer.
Light and Shadows
Light comes from many things. Can you see light from the Sun? Is there a light in your
room?
Making Shadows
Light can go through some things. Light cannot go through
other things. A shadow is made when
light is blocked. Stand in the Sun’s light. Your body blocks the light. The
light cannot get to Earth. There is a shadow. It is the shape of you!
Changing Shadows
Shadows can change. Shadows are big if the light is close. Shadows are small if the
light is far away. Shadows are different at different times of the day. Shadows
are short when the Sun looks high in the sky. They are long when the Sun looks
low in the sky.
Energy Around Us
There
are different kinds of energy. A bus needs energy to move. It gets
energy from fuel. Fuel is burned to make heat or power.
Gasoline is fuel for the bus. Gasoline burns.
Then the bus can move.
Wind is moving air. Wind has energy. Energy from wind can
make things move.
Electricity gives energy too. Energy from electricity makes things
work. Electricity moves from power lines to a plug. The energy moves into the
cord from the plug. A battery stores energy. This toy car uses energy from a
battery.
Energy for You
People need energy too. We need energy to grow, change, and
move. People get energy from food. You
use energy all the time! You use energy to play. You use energy to rest. You
use energy to read this book. You even use energy to blink your eyes!
Look at this house. Energy comes from Look around you right
now. You will see all around. Can you name the things energy comes from?
