• A person at the top of a hill

• An acorn falling off a tree

Multiple Choice

What is the possible or stored energy in an object called?

• Thermal Energy

• Kinetic Energy

• Chemical Energy

• Potential Energy

Solar Energy

• Sometimes the kinds of energy overlap eachother

• So, its not always clearly potential or Kinetic

• Energy from the sun is Solar Energy

• Solar energy can power calculators and other small electronics

• These use solar cells to change the light into electricity

Solar

• The sun also gives off several different kinds of radiation

• Light is the radiation we see

• Heat is the radiation we feel

• X-ray and ultraviolet are the dangerous kinds that we don't see or feel

• Also gives off radio waves- That's the static you hear on the radio

Solar Energy

• Without the Sun, Earth would be just a big ball of ice

• The heat is what allows life

• The light allows plants to make food and give off oxygen

• The sun is the source of all the energy(fossil fuels et) and all the weather

• Uneven heating is what gives us wind and the water cycle

Solar Energy

• Light can generate electricity( calculators, outdoor lights, and even cell phone chargers

• Provides electricity for homes that are far from electric lines

• Heat swimming pools

• The suns energy is free but the panels are expensive

• Lastly some places don't get all that much sunlight
