In this episode of Crash Course Kids, Sabrina gives us a real world example of how the Hydrosphere and Geosphere affect each other in the form of Weathering and Erosion. Think of Weathering as the force that makes a mess and Erosion as the force that cleans it up.
Weather and Climate... are they the same thing? No they are not. But they are both super important to how the geosphere is shaped. In this episode of Crash Course Kids, Sabrina chats with us about the differences between Weather and Climate.
This lesson from NASA explains how the Earth's tilt causes the seasons. There are also links to related resources on the webpage.
We know that the Earth is divided into four spheres (The Hydrosphere, the Biosphere, the Geosphere, and the Atmosphere). But, how do these different sphere interact with each other? In this episode of Crash Course Kids, Sabrina chats with us about how two of the spheres do, in fact, work together.
EARTH AND SPACE SCIENCE
This short animated video is the first part of a two part series on carbon dioxide and carbon capture and storage. Part one explores where carbon dioxide comes from, the role it plays in the atmosphere, and the efforts that humans are making to control, reduce and mange carbon dioxide emissions. For Part 2, check out "Do you know what carbon capture and storage is?".
ABOUT THE SCIENCE
There are many ways that plants benefit both humans and animals. Humans and animals breathe in the oxygen that is created by plants and in return they exhale, or breathe out, carbon dioxide. Plants then take in the carbon dioxide and release more oxygen.
Carbon dioxide, also known as CO2, is a naturally occurring substance that is made up of carbon (C) and oxygen (O2). Both humans and animals exhale carbon dioxide into the atmosphere, but it can also come from decomposing bio-matter.
Carbon dioxide is considered a greenhouse gas, which is to say it helps to control the Earth’s temperature by keeping thermal energy from the Sun in the atmosphere. Many of the things we do every day produce greenhouse gasses and it is important for us to control, manage and reduce the amount we put into the atmosphere. Too much or too little cause an imbalance in the Earth's temperature. Some things you can do to help reduce the greenhouse effect are practical and easy to put into use:
• Reduce, reuse, recycle can help reduce the CO2 .
• Take up walking and biking instead of using the car.
• Use less hot water in the shower or the laundry.
• Save on electricity. Use that “Off” switch.
• Plant a tree every year you are in school or celebrate a special annual event by planting a new tree! Earth Day is April 22nd!
During this activity, students learn how oil is formed and where in the Earth we find it. Students take a core sample to look for oil in a model of the Earth. They analyze their sample and make an informed decision as to whether or not they should "drill for oil" in a specific location.
