Reword the following.

The scientific concept that was demonstrated was the mechanical advantage that can be achieved with gear ratios. The idea is that gears can be used to accomplish something with less force. In this demonstration, a motor was used that could not exert a force of nearly 200 kg or make a wheel spin nearly 5000 RPMs, but with gears, the force that it could exert was magnified. It was demonstrated by taking a relatively underpowered motor and using gears to increase the amount of force it can put out. The demonstration was altered to where the motor was able to turn a wheel much faster than it could without gears, achieving more RPMs rather than force.

A very scientific tool was used in this demonstrationthe all powerful lego. A force meter was used to measure how much force the motor could put out on its own and with gear ratios. In the second demonstration, an RPM meter was used to determine how fast the wheel was spinning.

The data collected here was quantitativegood solid numbers. Math was used to determine the gear ratios and tools were used to measure things like RPMs and force. The data here can be measured, so it is quantitative data.

A different demonstration that would test the same science concept would be a demonstration that showed how a transmission works in a car. Lower gears create more torque, and higher gears operate more efficiently. It's a perfect example of how gears can be used to achieve higher efficiency.
