Year 9 - HEAT TRANSFER

Big Question - Can Heat Knowledge Save the World?

In Malaysia we try to keep cool and stop heat entering our buildings. We waste energy resources cooling it.
In cold climates, in the winter, the battle is to keep heat in a building and stop energy escaping. When it does escape energy resources are used to heat it.

Your Task:

Start by writing notes on the prompt question sheet.

Play the the attached PowerPoint on Heat Loss and Insulation BUT REMEMBER - whatever stops heat leaving a building will also stop it entering here!
Think about measures you could take in your home to keep it cooler without air con.

What you will be doing in the lessons:

You will be working independently in your groups to study this topic.
You will use a copy of the sheet below to keep track of your progress during the 3 lessons when you are experimenting and researching.

What each group needs to do:

Make a Tackk linking all of the following things together sorted by heat transfer method

  • An explanation of each process
  • Examples of where the process can be found / is useful
  • A copy of each process Question sheet completed and marked
  • A Copy of each Process Mini Quiz / Test corrected
  • A video summary of the experiments you did

The Roles you need to share out:

  • Resources Manager - ensure all information is completed and available for the Tackk
  • Tackk Producer - overall co-ordinator and support for resource manager in early weeks
  • Video Producer - record video and photos as appropriate and document support in lessons

You will all need to work together in class and liaise when you are at home, to make sure the content and question answers are of the best standard your group can manage and that the Producers have everything they need to do their job.

Week Plan:

  • Week 1 - Introduction to the problems connected with heat in Hot and Cold climates.
  • Week 2 - Kinetic Theory Test.
                  Understand what is meant by Hot, Cold and Heat.
                  Homework research Conduction, Convection, and Radiation.
  • Week 3 - Main chance to complete experiments, do Mini-Tests and Quizzes if you
                  get a chance. (Hwk Test Review)
  • Week 4 - Finish experiments, complete Mini-Tests and Quizzes.
                  (Hwk - work on Heat Transfer)
  • Week 5 - Consolidate and Summarise Heat Transfer.
                  (Hwk Practice Questions for revision)
  • Week 6 - Prepare for Year 9 Consolidation Test in class. Bring any queries
                  (Hwk Revise)   
  • Week 7 - Consolidation Test. (Hwk Complete all resources for Tackk.)

Make sure you use your Textbook or the link below, to get the detail you need for your explanations. Precise use of technical language is essential to gain top marks.

Conduction can happen in liquids but it is slow - heat is usually transferred by another method in liquids. (See the animation below to view the mechanism, but it must be on a laptop)

Conduction can happen in gases, but it is very slow - heat is usually transferred by one of the other methods UNLESS the gas is trapped. (See the animation below  to view the mechanism, but it must be on a laptop)

Convection happens in  fluids (liquids or gases) if particles are free to circulate and not trapped in small spaces,

Radiation happens in open spaces where there is room for the radiation to pass between particles, either a vacuum or gas. In the link below the information printed is very advanced but scroll down to see the animation. Do be aware that you cannot actually see the waves which make you feel hot when they hit you, this shows that other waves are also emitted at the same time.
