This is the second part of the two part tale of the puzzle that is Earth. In this episode, Sabrina talks about the Hydrosphere and the Atmosphere and what is contained in each one.
This lesson introduces the ways that engineers study and harness the wind. Students will learn about the different kinds of winds and how to measure wind direction. In addition, students will learn how air pressure creates winds and how engineers build and test wind turbines to harness energy from wind.
Students explore the causes and effects of the Earth's ozone holes through discussion and an interactive simulation. In an associated literacy activity, students learn how to tell a story in order to make a complex topic (such as global warming or ozone holes) easier for a reader to grasp.
Students learn how scientific terms are formed using Latin and Greek roots, prefixes and suffixes, and on that basis, learn to make an educated guess about the meaning of a word. Students are introduced to the role played by metaphor in language development.
Students are introduced to the basics of the Earth's weather. Concepts include fundamental causes of common weather phenomena such as temperature changes, wind, clouds, rain and snow. The different factors that affect the weather and the instruments that measure weather data are also addressed.
