How do we keep things How do we keep things warm? warm?
Success criteria I can explain that some materials are good insulators, while others are good conductors of heat. I can plan a fair investigation to test the insulation properties of a material.
Vocabulary insulator conductor thermometer investigate fair test
If I used boiling water and put it straight into the flask, do you think that it will still be warm?
What other examples of materials being used as insulators can you think of? Can you think of any examples of good thermal conductors?
How can you prove which materials are good thermal insulators? Change these variables Keep these variables the same You must plan a fair investigation.
Plenary Which variable made the greatest difference? Are there any variables that made no difference? What do our results tell us? Can we write a rule? The .. the , the warmer the water stays. Click on me for some information from BBC Bitesize
How does this relate to global warming? How does this relate to global warming? How can thermal insulation help save energy in our school building? What is the insulating layer that protects us by absorbing some of the sun s damaging ultraviolet rays? What is the insulator that is keeping too much heat from the sun in our atmosphere? How will global warming affect different parts of the world?
