Hot Chocolate Experiment
After planning our experiment last week, it was time for Class 6 to see what
material is the best insulator! We used 4 different types of material - cloth,
tin foil, bubble wrap, cotton wool and newspaper. Next, we wrapped cups with
the materials, filled it with a bit of delicious hot chocolate and measured the
temperature every 15 minutes using a thermometer.
Can you guess what the best insulator?
