What is the Dew Point?




Today the students became meteorologists. They created a class barometer to measure air pressure and reviewed the type of weather that is associated with high pressure and low pressure.

We also discovered the dew point for today by adding ice to water in a soup can. We recorded the temperature of the water before we added the ice. We added the ice and stirred the water until condensation formed on the outside of the can. We recorded the temperature when the drops formed and found out the dew point. We discovered that our temperature was very close to the dew point on the weather channel website.

We heard the story of Gnadenhutten and how the American Revolution affected the Christian Delaware Indians. It was a very sad story and one that we will remember for a long time.
We reviewed fact and opinion and completed a worksheet about facts and opinions from our Revolution reading. The students really remembered this skill and were very confident in their abilities.
