Which spoon is best?

Our science work on fair testing and materials over the last two weeks has been linked to the story of Goldilocks and the Three Bears! Which spoon would be best for Father Bear to stir the hot porridge with so he didn’t burn his hand?

In the first week, Mrs Wadey demonstrated it all wrong and didn’t make it a fair test at all – she had different sized pots, different sized spoons and put the spoons in all at different times. We were challenged to do better!

We had to choose our equipment from a vast selection to carry out a fair test to see which spoon conducted heat the least and would keep Father Bear’s hand cool whilst he stirred and made the porridge for breakfast – wood, plastic or metal?

Many of Y3 and Y4 devised ways of recording their own results and others worked together to create a table. Most children found out, concluded, that metal would get warm quite quickly and so wouldn’t be a good choice for Father Bear. Our discussion about why metal spoons were OK for eating but NOT good for cooking were interesting too and included thinking about how long the spoon was in contact with the hot food! Great scientific thinking and recording on this by all.
