Three common methods of trimming feathers. It consists of two wires of two different materials that are joined at each end. Now you'd really have some explaining. Students Tara, Emily, Krystal and Cassie Edwards wound the laboratory jack down and eventually the magnet broke away from other Peoples Money the plate.

You could investigate friction for objects being shot up an incline and coming to rest (what to vary, what to control?).

Repeat this in a uniform and periodic fashion. This suggests a great EEI though. What physics principles are being tested? A good research question is "for what angle will the horizontal speed be the fastest?" or if you are measuring the time to travel strengths and Weaknesses of the European Union across a table (see diagram below) "for what time of travel across the tabletop be the least"? Should energy input be kept constant, or just time?
