Make a Balloon Ec-Static  
In this activity, students create static electricity by rubbing a balloon on their hair or clothing. When you rub a balloon on hair, shirt, or sweater, the balloon will attract things toward it. The rubbing scrubs electrons off and they collect on the surface of the balloon. ,

Static Strength Tester  
In this activity, students make a static strength tester by suspending a Styrofoam ball from a string. When the ball is brought near static-charged balloon, it is repelled. How much it is repelled is a function of the static charge strength.

The Great Electron Rip-Off  
In this activity, students explore static electricity using transparent tape. When two pieces of tape are placed on a table top and then ripped up, they repel each other when brought close. This is because they lost electrons when they were pulled from the table. Since they have the same charge, they repel each other.

Buzz on Electrolytes  
When you sweat you lose important electrolytes like sodium, chloride, and potassium. One major function of electrolytes ,is that they help to conduct electrical currents in your body and allow muscles to contract and relax. In this activity, students build a simple conductivity detector and use it to test a number of household substances.
Secret Circuits  
Students make a circuit detector by connecting a light bulb to a battery and a wire. , The circuit detector is actually most of a circuit but not all. There needs to be a way for electricity to flow from the end of the wire to the bottom of the bulb to complete the circuit. Students use the detector to uncover hidden circuits prepared by their teacher. ,
Metals ? They?re Electrifying  
Some materials conduct electricity and others don't. In this activity, students use a simple circuit detector to test a few common items to determine which of them conduct electricity.
