Information about science projects on insulation?

There are many possible science projects dealing with insulation. For example, build several small containers with each wrapped in a different insulating material, then put an icecube (all the same size!) in each container, and see how the time needed for the icecube to melt varies depending upon the type of insulation used. Or put a small light bulb in each container (all of the same wattage!) and then measure the resulting temperature in each container after ten minutes. Or make blankets of various different insulating materials and see which one keeps you warm at night the most effectively.
