 The danger of static electricity at gas stationsAccidents have been known to occur at gas stations, when on especially dry days, static electricity is discharged as a driver exits or enters his car. This is especially dangerous at gas stations, as the sparks that occur during discharge sometimes lead to explosions. This science fair project was performed to investigate the amount of static electricity discharged between car seats, clothing and

 What materials work the best in a sandbag for preventing a flood?The purpose of this experiment was to see what materials work the best in a sandbag for preventing a flood. Fine and coarse gravel, plant soil, and mulch are not usually put in sandbags to stop floods. Most people do not have a lot of sand that they can put in sandbags. That's why I'm doing this experiment, to see if fine and coarse gravel, soil, or mulch can have the same effect as sand.

 What sort of blade design works best for windmills?The purpose of this experiment was to determine which windmill blade sizes, shapes, and angles were most efficient at producing an electrical current from a generator.
Difficulty: Middle school
 Which types of film are most tolerant to light?The purpose of this experiment is to determine what film speed is most tolerant to light out of three speeds of film. (100, 400, 1600 speed film)
