Extended Learning
• Write a plan for an investigation to test which is a
better insulator, a natural fibre like wool or artificial one
like nylon. Include hypothesis, materials, variables,
method and table of results. Include in your method
how you will make the test fair.

New Information for Learning Outcome 3
Explore and Discover:
• Visual: observing the slides
• Audio: listening and sharing ideas in
the discussion
• Kinaesthetic: handling the
thermocolour film
10:05
Learning Activities for Outcome 3
•Feel the metal ruler and the plastic ruler
that both came from the refrigerator.
•Which one feels colder? Why?
The metal ruler feels colder because it
is absorbing more heat from our fingers
than the plastic ruler. Metal is a better
thermal conductor than plastic.
10:05
Learning Activities for Outcome 3
1.Now, using thermocolour film, press your hand on the film,
what did you notice?
2. Put the film on top of a metal plate and press your hand on
the film; then remove your hand and observe. What did you
notice?
3. Next put the film on top of a wooden board or on top of your
table and press your hand; then remove your hand and
observe. What did you notice? Compare to what happened
when the film is on top of a metal plate.

TASK 3:
Showing your own understanding, explain why
different objects feel warm or cool even if they
have the same temperature. Use the concept
of thermal conductivity in your explanation.

Review
• Swap books with the person next to you and look over
their work. Write a WWW and EBI statement.
• Stand up if you have developed some skills this lesson?
What are they?
• Tell the person next to you three things you have learnt
this lesson.
• Did you successfully complete tasks at your target level?
• If not, what do you need to do next in order to meet your
target level? Record this in your diary to be done as part
of your extended learning at home.
• Is there any part of the lesson you think you need to go
over again next lesson?
• How will you remember what you have learned today for
your exam?
