This trimester in Global Science I would like to learn about the atmosphere, hydrosphere, biosphere, and geosphere. I would also like to learn more about how these spheres interact everyday. Another subject in Global Science that I would like to learn about is the number of hours in a day and how they change constantly. And I'd like to learn about how these spheres have changed over time. I think that taking obsevations of these processes from each sphere can be exciting and fun.
