the question im thinking of is - does water stay hot longer in a foam cup, ceramic, glass or wax paper cup? i would put the same amount of water at the same temperature into all these cups and measured how long the temperature stayed constant with thermometers.
for the responding variable what do i measure? the temperature??

Measure temperature over time and plot on a graph. Determine if there is any difference in the rate of temperature change between the different materials. Determine if any other factors influence the results like room temp ect. Also include a vacuum thermos bottle in your testing as well as a metal cup...
This progject could benefit from a datalogger. Basically a device that lets a computer record measurements at a prescribed interval. Check the link below as qualified students can receive a free data logger...

wouldnt your variable in this case be the different type of cup. The material that the cup is made up of will contribute to how long it keeps the boiling water hot for. You are measuring which material keeps water hot the longest!

I am thinking foam. Another way to look at this is: What gets hotter on the outside when hot water is in it. The heat has to go somewhere.
Additionally, you need to consider the amount of open space on the top of the container.
