Family Science Saturdays

Family Science Saturdays is a fun, hands-on class for scientists of all ages. Each month focuses on a broad topic with a related class each week. These classes are designed to build on each other throughout the month, though you can still participate without attending every class. For the month of July join us for an exploration of Earth Systems. 07/02/16 - Biosphere The term "biosphere" was coined by geologist Eduard Suess in 1875, which he defined as the place on Earth's surface where life dwells. Learn more in the MONAS classroom 07/09/16 - Hydrosphere The hydrosphere in physical geography describes the combined mass of water found on, under, and over the surface of a planet. This includes water in liquid and frozen forms in groundwater, oceans, lakes, and streams. There is an estimated 1386 million cubic kilometers of water on Earth. Learn more in the MONAS classroom. 07/16/16 - Atmosphere An atmosphere is a layer of gases surrounding a planet or other material body, that is held in place by the gravity of that body. The atmosphere helps protect living organisms from genetic damage by solar ultraviolet radiation, solar wind, and cosmic rays. Learn more in the MONAS classroom. 07/23/16 - Geosphere There are several conflicting definitions for geosphere. The geosphere may be taken as the collective name for lithosphere, the hydrosphere, the cryosphere, and the atmosphere. In modern texts and in Earth system science, geosphere refers to solid parts of the Earth. Learn more in the MONAS classroom 07/30/16 - Pedosphere The pedosphere is the outermost layer of the Earth that is composed of soil and subject to soil formation processes. The pedosphere is the foundation of terrestrial life on this planet. Check out the MONAS classroom for a presentation and activity to follow. Learn more in the MONAS classroom.
