Why do we bundle ourselves up when we want to stay warm? Well, insulating, or adding layers of different materials, helps us to conserve heat, or in some cases, stay cold. We see this in the walls of our houses, fridges, freezers, cooler boxes, etc., too. Build your own insulated box to see if your popsicle can withstand heat!
What are some examples of insulation that you have encountered?
What do you think might make a good insulating material?
Do you think that more layers or less layers will be most successful?
Is there a way that you can design your container so that you can easily check on the popsicle?
Out of any materials, design a container that will keep your popsicle cold
If your Section is feeling competitive, put a popsicle in each of the designed containers and begin the timer. Keep one uninsulated popsicle outside the containers for comparison. Check on the popsicles every five minutes – the last popsicle that is still frozen wins!
Don’t forget about the mess as the popsicles begin to melt.
How well insulated was your container? What could you have done to improve the insulation?
What do you think made the winning container so successful?
Think about insulated materials that you’ve encountered (like your home, refrigerator or thermos). How important do you think it is for insulation to be sealed?
