This 13-minute video lesson looks at plate tectonics and the evidence of plate movement. [Cosmology and Astronomy playlist: Lesson 45 of 85]
This 6-minute video lesson continues to explore plate tectonics. It covers the geological features of convergent plate boundaries. [Cosmology and Astronomy playlist: Lesson 47 of 85]
This 6-minute video lesson coninues to look at plate tectonics. It discusses plates moving due to convection in mantle. [Cosmology and Astronomy playlist: Lesson 48 of 85]
This 9-minute video lesson looks at refraction and focuses on refraction in seismic waves. [Cosmology and Astronomy playlist: Lesson 53 of 85]
This 11-minute video lesson attempts to comprehend the size of the universe and the scale of the large. [Cosmology and Astronomy playlist: Lesson 57 of 85]
This 9-minute video lesson considers seismic waves and how they are related to the composition of the Earth. It covers both S-waves and P-waves. [Cosmology and Astronomy playlist: Lesson 51 of 85]
This 10-minute video lesson covers the structure of the Earth: The crust, mantle, and core. [Cosmology and Astronomy playlist: Lesson 44 of 85]
This 6-minute video lesson looks at the Mohorovicic Seismic Discontinuity: the boundary between crust and mantle (or Moho). [Cosmology and Astronomy playlist: Lesson 54 of 85]
This 4-minute video lesson explains why S-Waves only travel in solids. [Cosmology and Astronomy playlist: Lesson 52 of 85]
What are air currents? Air currents are like rivers of wind caused by areas of high and low pressure.The air above the land is warmer and less dense, so it rises. The air over the water is cooler and heavier. The cool air rushes in toward the low-pressure zone over the land, forming a lovely sea breeze. But what about Jet Streams? In this episode of Crash Course Kids, Sabrina chats with us about all things relating to Air Currents.
In the deepest, darkest parts of the oceans are ecosystems with more diversity than a tropical rainforest. Taking us on a voyage into the ocean -- from the deepest trenches to the remains of the Titanic -- marine biologist David Gallo explores the wonder and beauty of marine life. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 8-minute video. Educators may use the platform to easily "Flip" or create their own lesson for use with their students of any age or level.
Let's continue the exploration of the Water Cycle by drinking some dinosaur pee. Yep! Well, it's a little less gross that it sounds. It turns out that all of the water on Earth is just constantly recycled in what we call a closed system. No water comes in and no water goes out. So that means that, at some point, it's possible the water we're drinking was once dinosaur pee... or tears...
This map shows the distribution of the top 12 items picked up on Canadian shorelines across the country in 2017. A shoreline is anything that is connected to water: which includes coastlines, lake shores, river shores, inland communities, and storm drains. Marine debris is coming from all across the country. Do you use any of these items? What actions can you take to reduce the impact? Find out more.
Student teams commit to a final decision on the location they recommend for safe underground cavern shelter for the citizens of Alabraska. They prepare and deliver final presentations to defend their final decisions to the class.
The official Earth Day website showcases a variety of information surrounding this impactful day. The information includes Projects, Challenges, Videos to provide background information about the our world today and challenges and projects that your classrooms can participate in to make a difference in our world now and for the future. In addition, the website has downloadable ToolKits for your classrooms.
