Wed. March 24 Transfer of Energy

Energy is the ability to do work, or in more simple terms: energy makes things happen. You use energy to ride your bike, play video games, bake cookies, and drive to school. Energy is exciting! Energy can be transferred from one object to another, and energy can be transferred into different forms, such as light, sound, and heat

Energy transfer takes place when energy moves from one place to another. Energy can move from one object to another, like when the energy from your moving foot is transferred to a soccer ball, or energy can change from one form to another.

When energy in a battery is used to power an electronic device, chemical energy is transformed into electrical energy, which moves along wires

Light energy is the only form of energy we can see. Light from the sun helps plants grow and makes food for us to enjoy. The sun’s energy also powers solar cells, which can be used to create electricity.

Light bulbs can also transfer energy, just like in the video when the light bulb’s energy powered the singing fish. The light energy moves through space until it encounters a solar cell. The solar cell converts it to electrical energy, which powers the singing fish.

Have you ever felt sound? Loud concerts or even marching bands can sometimes produce enough energy that you can feel the vibrations in your body.

Sound energy is transferred when a sound wave travels from its source, like a drum, to another object. If the sound is loud enough, the waves will create very intense vibrations that you can feel in your chest.

When you sit by a campfire, you can feel the heat warm your body. The heat from the burning wood is transferred to your marshmallow, causing it to get soft and gooey. Perfect for your s’mores!

Heat can move from warm objects to cool objects, just like in the video when the heat from the wires made the paper ignite.
