We explored forces by experimenting, exploring and discovering. We set up fair tests, identifying and controlling the variables. Water resistance We set up an experiment to find the shape with the least water resistance. Air resistance We experimented with different sized parachutes, to see which produced the most air resistance. Pulleys We set up an experiment to see how pulleys can help with lifting loads. Levers We experimented to see what happens when we change the length of the lever.
