1. Exploration
What can you learn from your coat?!

                     first put it on?
1. Exploration

• Why does your coat keep you warm?

• What does it feel like when you put on a coat
  that someone else has been wearing?

• What does it feel like when you take your coat
  off?

• What does this tell you about keeping warm?
• What ideas do your group have about heat and
  why things get warmer and colder?
2. Scott of Antarctica




• How did Scott and his men
  attempt to keep warm?
• Where does their warmth come from?
• How could they have kept warmer?

• What has enabled more recent polar
  expeditions to be successful?
 3. Huddling Penguins




• Why do the penguins huddle together like this?
• What happens to the penguins on the inside of
  the group?
• What happens to the penguins on the outside of
  the group?
• How does this help your ideas about heat and
  why things get warmer and colder?
4. Huddling Penguins in the classroom

 • What happens to the temperature of the test
   tubes over time?
 • Why do you think this happens?
 • How does this relate to the behaviour of the
   penguins?
 • Does this evidence support your existing
   ideas about why things get warmer and
   colder?

• Why are there no numbers on the axes?
  Does this matter?
• Which line represents the best insulator?
  How do you know this?
• What kind of materials do you think were
  used for A, B and C?
• How does this help you understand why
  things get warmer and colder?
6. The snowman’s clothes


                          I think he won’t
                          melt because it
                             isn’t sunny.



                  I think his head
                 will melt because
                 the hat is warm.



      I think we should put
          my coat on him
         because that will
          keep him cold.
                                             Woof!

7. Back to the start and future learning

 • How have your ideas changed today?
 • What progress have you made with your
   understanding of why things get warmer and
   colder?
