The what's and why's of the experiments looking at how resistance of a conductor varies with temperature. Here, two materials are examined, a coil of wire and a thermistor (page 263 & 264)
The what's and why's of the experiment to show Upward forces = Downward forces and Sum of Clockwise moments = Sum of anticlockwise moments (p 121)
The what's and why's of the experiment carried out to Verify Boyle's Law (reference page 111 - 112)
A description of what to do and why for the experiment to show that acceleration of a body is directly proportional to the force acting on it (page 91-92)
Hopefully this will give some clarity on how to return assignments and make things a little easier for you.
