Lead an experiment to see how insulation plays a part in keeping things hot or cold. Your students will test the temperature of water in two different mugs to learn which one keeps the water warmer and why.
For each group of 2 to 4 students:
Insulation is defined as a material that limits the travel of heat, sound or electricity from one place to another.
Insulation comes in many forms like fur, feathers, and fat which help keep animals warm in the winter. We dress warmly when we go outside in the winter. When indoors, we can choose to wear a sweater or use a blanket instead of turning up the heat to save energy. Many travel mugs or flasks are insulated using an air gap, similar to double-glazing for windows.
Buildings are constructed using insulation in the walls and roof. More insulation means that less heat is lost from the building, resulting in energy savings.
