In Science class, we learned about static electricity.  Sometimes you think of static electricity as non-harmful, but it can be very deadly.  For example, lightning has killed many thousands of people over the years.  Lightning is a kind of static discharge.  We have experimented with balloons in class, to see how static works.  Our experiments showed us the properties of static electricity.  Static can be very interesting, but remember it can be very deadly.

We watched a video about static discharge.  A lady went to fill up her car with gas.  As she went to fill up her tank, she released the static discharge that she had.   By touching the door, she released her static electricity.  But when she got in the car again, she had been rubbing her clothes against the seat, and then got out and never discharged her static.  When she touched the gas nozzle, the fumes ignited from the spark of static discharge and there were flames.  Luckily, the lady did not get hurt.

In Science class we learned about electric motors.  In fact, we even made one.  Most of the motors didn't work and we learned that you might have to change some variables.  We used electricity and magnetism to try and make the coil of wire spin freely.  Electricity flowed through the coils, then there were magnets under the coils that repelled and attracted the coils.
