One simple experiment is to verify Newton's Law of Cooling. All you need is a container of hot water and a thermometer, in a room which is at a steady temperature. Measure the temperature every minute whilst the water is cooling, and plot a graph of temperature against time. Then from the graph estimate the rate of cooling (the slope of the graph) every few minutes, and plot rate of cooling against difference in temperature between water and room (ambient). From the result deduce how rate of cooling varies with temperature.
If you can obtain some paraffin wax, you can show the effect of latent heat. Melt the wax carefully, but don't make it too hot, it could burn. Then let it cool and plot temperature against time as for water. When the wax starts to solidify you will see the graph change slope, this is due to latent heat being released as the wax solidifies.
