IV - The miracle grow (since this does not change based on the dv)
DV- The height of the plant (since it depends on how much/ wether miracle grow was added.)
Control- The control would be the plant without any miracle grow
Hypothesis- If miracle grow is added to the plant, then it will grow taller because it will give the plants the nutrients it needs.
Electrons are added to your body as you shuffle your feet across the room. Then the shock is when they discharge from your body to the doorknob when you touch it.
The resolution of the angles measured (which is to 2d.p) is greater than the resolution that a normal protractor would show (no d.p)
e.g You can't really put a protractor down and say that's exactly 27.94 degrees, so something more accurate must've been used
