1. Look at the picture below. Why do Fred’s and Jenny’s spoons feel different? 4 What is the difference between the thermal conductivity of metals and non-metals?
The spoon is so hot!
Mine doesn’t feel hot.
Activity Booklet 25 2. Do this experiment to compare the thermal conductivity of metals and non-metals.
plastic rod
wooden rod
copper rod
butter
a glass with hot water
Quick Check Copper (metal) conducts heat more quickly / slowly . It is a good / poor thermal conductor. Wood and plastic (non-metals) conduct heat more quickly / slowly . They are good / poor thermal conductors.
