School project on energy transformers

hello
I need help with :Construct a simple hand-drawn diagram (in pencil), which shows how this energy transformer works including labelling of parts & annotations to explain how it works. Construct a flow diagram to identify the energies involved at each step. Use arrows to show the transfers and transformations.

I chose a halogen heater as my appliance.
please reply asap!
thanks a million!

Hi, Andrea. I know what an electric heater is, but I don't know specifically where halogens fit into the process. I don't know why you chose a halogen heater, but you should start with the literature for halogen heaters, which should describe how they are reputedly better than regular resistance heaters. After you understand generally what the product you want to talk about is, and how it works, then you can look at the energy in and energy out. Does the incoming energy for the heater you chose come from propane or electricity? Since it's a "heater" the desired form of output energy is heat. Surely you know how to label components and annotate a sketch. Good luck.
