For each of the following case studies name the:- (A) independent variable (B) dependant variable
(C) Control variable (D) Draw a
results table for each.
Extension: For each of the variables state if it is continuous or discrete
Can you think of any ways to improve the experiments?
Case study 1 - Measuring gravity.
The aim of this experiment is to find out how fast objects of different masses take to fall from height. To conduct this experiment we used a number of different sized steel ball bearings, which had different masses. Each ball bearing was weighed on scales, before being dropped from a marker exactly 2 m from the floor. The time the ball baring took to drop was timed on a stopwatch, and repeated 3 times for each ball-bearing to gain an average time.
