1. Energy
17/11/2018
Objective
To describe changes in materials due to temperature changes.

2. Starter 3oC 0oC -34oC to 8oC 37oC 100oC
Estimate the temperature in each of the pictures:
3oC
0oC
Check that pupils understand the concept of an estimate. Arctic temperature shows average for winter and summer.
Extension: Write up 5 temperatures on the board (including negatives) and get pupils to rank them from lowest to highest.
-34oC to 8oC
37oC
100oC

3. Temperature and Heat Energy
Discuss with the person next you, the difference between temperature and heat energy. Temperature – A measure of how hot an object is. Heat Energy – The energy which moves from a hotter place to a cooler place. Explain what would happen to the water in the cups, using both keywords, temperature and heat.

6. Plenary 1 Energy can be moved around in the form of heat. a)
We can measure how hot something is. What do we call this measurement? b)
An object at high temperature is placed in room at much lower temperature. Which way is energy transferred?”
Temperature.
Heat energy moves from a hotter place to a colder place (from a place at higher temperature to a place at lower temperature).
