Good and Bad Heat Radiation Emitters Investigation

This simple worksheet leads the students through an investigation into which surface is the best at emitting heat radiation.
It can be easily adapted to include more or different materials depending upon what is available for your school.
There are questions at the end to test the students understanding of variables and a graph plotting exercise suggested.
After the experiment there is an extension exercise for the students to plan an investigation into the best reflector of heat radiation
A research activity on Heat Radiation is also suggested and a Youtube link to watch a fun video
