We have had a wonderful time experimenting with materials in Team Starlings today! We have been investigating which material is the best thermal insulator. We tested felt, bubble wrap and paper, wrote a very detailed method, making sure to include our control, independent, and dependent variables. Hot water was put into each container and the temperature taken at 5 minute intervals and put into our table. Our results surprised us- which material do you think we found to be the most effective insulator?
