Our sun and other stars release light energy. At least this is what we see. Our Sun and stars also emit more than just light. Scientists call the type of energy that our Sun and stars release electromagnetic energy. This form of energy travels through space. Electromagnetic energy includes the light we see. It also includes much more. Many of these things we know about, but dont always think about. Electromagnetic energy includes radio waves, microwaves, and X rays. We now have devices in our homes and offices that release these same forms of energy. We use electromagnetic energy to make our lives better.
What question would one ask from this paragraph?
Answer: What does electromagnetic energy create that we see when it travels through space?

Once upon a time Jimmy had a mother who told him that he was good at music. Jimmy wanted to play music. He did not know which instrument to play, so he tried a piano first. The piano went like a sound. Then he tried a guitar. The guitar played. His brother told him that the piano was better to start, so Jimmy played the piano. He hammered on the keys. Jimmy's brother liked this, but mom did not like this. Jimmy tried playing very quiet. Jimmy's mom liked this, but Jimmy's brother did not like this. Jimmy tried playing in the middle. Jimmy liked this, and Jimmy's mom liked this, and Jimmy's brother liked this. It was great.

Answer: When Jimmy hammered on the keys, who didn't like it?

Magnets are able to place a force on certain materials. This force is called a magnetic force. The force a magnet exerts is a little different from the forces you may normally think about. You exert a force on a book when you lift it. You also exert a force on the pedals of your bicycle. In both those cases, those forces cause a change. The change you see in both these cases is called motion. Magnets, too, can produce change. They can produce motion just like you do. Unlike you, magnets do not have to touch something to exert a force. A magnetic force is exerted over a distance. Thats right, a magnet can push or pull certain items without ever touching them. Thats how the maglev train works. Do you know another type of force that does not require objects to touch? These forces are known as non-contact forces. Another type of non-contact force you may be familiar with is gravity. Gravity too can cause changes in motion. Gravity holds our moon in orbit without touching it.

Answer: The force you exert on your bike pedals that causes change is called what?

Surely, you have noticed the tall poles along the roadside. Do you know what is on top of those poles? Thats right, wires that carry electric current. These wires carry electric current to your home. But what is electric current? Electric current is actually the flow of electrons. You may recall, an electron is the outer-most particle in an atom. They have a negative charge. Electricity is the continuous flow of these particles. Electrons are able to move through wires. Their speed can even be measured. The SI unit for electric current (or speed) is the ampere (A). Ampere is often shortened to amp. Electric current may flow in just one direction, or it may keep reversing direction. Direct current (DC) flows in only one direction. Direct current is what is used in devices like flashlights. Alternating current (AC) flows in two directions. This is the type of current that flows into your home through wires.

Answer:
Where are the wires that carry electric current to your home?
