How does insulation work?

If I am going to conduct an experiment on insulation, one of the first things I need to find out is how insulation works. After doing some research, I now have a pretty good understanding of how insulation actually works.

Heat naturally flows towards cold air. This is why heat always tries to escape your house in winter, making it chilly inside, and why heat always tries to slip into your house in summer, making it hot and stuffy. This is where insulation comes in. Insulation can stop some heat from flowing towards the cold air. This way, you can keep heat inside your house in winter and keep the heat outside in summer.
