Science Date – Dec. 9 – 20th
Dec. 9 & 10 --Why don’t we see clouds everywhere in the air, and what is a cloud made of anyway?
We read about what clouds are made of, why we can see them, the role of clud condensation nuclei, and methods of cloud seeding. We argue for how what is happening in clouds is similar to what we see happening on the surface of a cold gel pack over humid air in our 2 – liter bottle.
Dec. 11& 12 – In this lesson, we use our Gotta-Have- it checklist to test and revise a thunderstorm simulation to produce larger and smaller storms. We focus on temperature and humidity conditions that are likely to produce storms. We also think about what additional ideas we would like the simulation to respresent for us, and we design interfaces for how those would function in the simulation.
Dec. 13&16 – In this lesson, we carry out an investigation to try to lift or suspend different objects (a piece tissue and a ping-pong ball) with air blown upward. We construct an explanation that counter balancing forces from air traveling upward and the force from gravity downward can keep objects suspended in the air. We develop a model to show how pieces of matter in the air might be lifted upward, fall downward, or remain suspended in the air, depending on the relative strength of each force acting on that piece of matter.
Dec. 17 – & 18 – We plan and carry out an investigation to determine what variables affect the amount of lift produced by transferring thermal energy into a fluid. We will explanin how the results of our investigation help us understand how differences between the air and ground temperatures and the amount of ground heated affects what happens in the air.
Dec. 19 – Students will complete a Christmas escape room.
