Come up with a way to improve the experimental design. Scenarios
1. Eric wanted to investigate what materials are good insulators. He filled 4 different containers
with water and sealed each one with the same kind of lid. He then wrapped each container with a
different insulating material and set them outside for 4 hours during a sunny day. To determine
which material was more effective he used a thermometer to determine the temperature of the
water in each jar.
