Problem: Tim had always a red bike. His birthday party was coming up and he hoped that his parents would finally get him the bike. When his friends came over for the party, Tim was very worried that he wouldn't get the bike. He looked at all the presents and none of them seemed big enough to have a bike in them. Tim was sad. When it was time to open the presents he opened them one at a time. The first present was not a bike. The second present was not a bike. The third present was the biggest one. Tim knew if the bike was going to be in any of the presents it was going to be in this box. Tim opened it and there was no bike inside. Just as Tim tried not to look too upset, his Dad brought in the biggest present of them all. His Dad had been hiding the present all along. Tim opened it and his new bike was inside the box. Tim put the bike together with his Dad's help.

Question: "What was Tims party for and who gave him the biggest present?"

Answer: "Dad"
Answer: yes

Problem: 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.

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

Answer: "Direct Home"
Answer: no
