It's a little chilly!

Our science topic this half term is seasonal changes. On Tuesday we were investigating which material is the best at keeping us warm. 

We each had a ball of ice with a little Lego man inside. He looked very cold! We decided we should warm him up! We felt and discussed the properties of several different materials. We made predictions on which materials we think would warm up the Lego man quickest. 
We them wrapped our ice ball in our chosen material and left him to thaw out! 

While we were observing our ice ball over time, we wrote our method. Some of us took a peek at our Lego man too often and the warm air that was being trapped by the material and melting the Lego man quicker kept escaping and it was taking longer! (This was explained brilliantly by Grace!) 

We discovered that the best material for thawing our Lego man was a very thick plastic bag. However, we decided that this wouldn't necessarily be the best material for ourselves in winter as it wouldn't be very comfortable! 






We also classified different clothing into Winter and Summer. We discussed the properties of the materials and why they are chosen to be Winter and Summer clothes.
