Grade 8 investigates wheelchair ramp slopes

Our grade 8 students are currently doing their physics unit on Forces, Work and Machine.

Their task for this week was to investigate how the slope of a ramp affects its usefulness in the context of building a wheelchair ramp to a public library. They modelled the situation with a wooden plank and block and studied the amount of force required to pull the block up at various ramp heights. They then interpreted the data and derived their conclusion to present which ramp has the most efficiency.
