A student investigates the bending of wooden strips of different thicknesses. She compares how far they bend when loaded at one end.

Plan an experiment to investigate how the thickness of the wooden strips affects the bending of the strips when loaded at one end.

The following apparatus is available to the student:

• wooden strips of the same material, length $$\begin{gathered} 1 \\ textm \end{gathered}$$ and width, but of different thicknesses
• a set of slotted masses
• a metre rule
• a G-clamp (used to hold the strips to the laboratory bench).

Other apparatus normally available in a school laboratory can also be used.

In your plan, you should:

• draw a diagram to show the arrangement of the apparatus
• explain briefly how you would carry out the investigation, including the measurements you would take
• state the key variables to be kept constant
• draw a suitable table, with column headings, to show how you would display your readings (you are not required to enter any readings in the table)
• explain how you would use the results to reach a conclusion.
