In continuation of our Composition of the Earth lessons, the children enjoyed learning about the Earth’s insulation. To begin the lesson, each child had a turn to feel the heat radiating off of a spoon that was heated up. From there we had a group discussion about the difference between warming your hands near an open fire and feeling the heat coming off of the spoon. From there, we talked about the two different types of heat: radiant and passive. Radiant heat comes from something burning; when the sun heats up the Earth’s surface. Passive heat comes from something that has collected heat from something that is burning; when the Earth’s surface heats up the atmosphere.
In addition, the children learned that as hot air rises, it cools and is forced to release moisture. To illustrate this concept, I boiled water in a pan and covered the pan with a cool glass bowl. Water droplets quickly appeared on the bowl because the coolness of the bowl allows the air to release its moisture. This is called condensation.
