Carrying out the investigation
Step 3 - Take the temperature in 1 minute intervals for 3 minutes.
Step 4- Put all the results together and see which material was the best to keep the temperature.
Our Outcome
We found out that the best material to keep in heat was the cotton wool .
The cotton wool kept the water hotter than the rest by 2 degrees more.
What I would do differently
Next time I would make sure that each material was exactly the same length and width.
I would also make sure the times were accurate.
