Science - Hot and Cold

1/2/2013

 
We made a concept map about how to keep warm: The children came up with lots of ideas:
Put on your coat, hat, scarf and gloves
Sit by the fire with a blanket around you
Jump up and down
run on the spot
Rub your hands together
Close the doors and windows
Put a hot water bottle in your bed

We tried an experiment to see which material would keep the hot water bottle the warmest. At 10 O'Clock we took the temperature of the water in each bottle - they were all 32 degrees celsius. We wrapped one in tin foil, one in bubble wrap and the third in wool. We took the temperature again at 1 O'Clock... check out our findings below. We were very surprised. Most children predicted that the wool would keep it the warmest.
