# Three Ways to Cook Your Dog

This page will help you learn about the ways that heat is moved from one location or object to another. Read through the information carefully. Then you might try to cook a hot dog using each of thethree different methods of heat transfer.

 Journal Entry - Take out your science journal and answer the following question(s) (use drawings as appropriate):

Look at the picture at the left and describe the movement of heat in your journal. Use the following words in your description: conduction, convection, heat, waves, radiation (heat transfer through space in waves), and particles.
Drag your mouse over the button at the right to view a possible answer that describes the movement of heat.

Do you know how to cook a hotdog using the three methods of heat transfer?

Pretend you are at home conducting this experiment.

Conduction: Heat transfer by direct contact. You will need a hotdog, a stove, and frying pan. Put the frying pan on the stove burner and heat it to medium-low heat. Place your hotdog in the pan and watch it cook by conduction.

Convection: Heat transfer by the flow of a liquid or gas in currents. You will need a pot of water, stove, and a hotdog. Fill the pot half way with water. Put it on the stove at high heat. When it comes to a boil, put your hotdog in, and watch it cook by convection.

Radiation: Heat transfer through space in the form of waves. You will need a campfire, a roasting stick, and a hot dog. Hold the hot dog above the fire. (Do NOT touch the flames with your hot dog!!!) Now watch the hotdog cook by radiation.

Analysis:

• Compare and contrast the three methods of heat transfer. Make a chart or diagram to show your answer.
• Based on your hot dog experience, describe how heat from the sun reaches Earth.
