What charges are in this kid's hair? He has a lot of like charges in his hair, so they are pushing away from each other.

Static electricity can be a lot of fun, but may be difficult to explain. So I recommend that you begin by experimenting with static electricity and then trying to understand what you have seen. I have linked a site with 7 seven static electricity experiments for you to try. Once you have tried some of the experiments, watch the videos below to learn more about the positive and negative charges at work.

Electrical Circuits
Electrical Circuits
There are a few key components for any simple electrical circuit to work. You need a power source (battery or electrical generator), wire and a bulb or device. A switch is also handy, so you can easily turn the flow of electricity on and off. There can be no gaps in the circuit or electricity will not flow.

Conductors and Insulators
Conductors and Insulators
Conductors are any objects that permit electricity to flow through them. The most common examples are any type of metal, such as copper, iron, steel, aluminum, silver and even gold. Water is also a good conductor of electricity, which is why you have to get out of the pool during a lighting storm. Insulators are materials that do not allow electricity to flow through them. Rubber and plastic are great insulators and that is why wiring that goes to your TV, computer and other electrical devices is encased in plastic.

Below is a video about how to make a potato battery. After watching the video you should now be able to impress your friends, but why stop there? There are hundreds of electricity experiments that you can do. You now know the basics of electrical circuits. Start experimenting! Make sure that you ask permission before you begin an electrical experiment and NEVER USE AN ELECTRICAL OUTLET AS PART OF YOUR EXPERIMENT. You should use batteries for all electrical experiments. For step by step instructions of the potato battery, click here.

b. Plan and carry out an investigation to observe the interaction between a magnetic field and a magnetic object. (Clarification statement: The interaction should include placing materials of various types (wood, paper, glass, metal, and rocks) and thickness between the magnet and the magnetic object.)
