Geography & Science: Did China Slow the Earth? Three Gorges Dam
By Geography and Math Made Easy
This geography and science lesson is intriguing and engaging! The construction of the Three Gorges Dam in China, the largest hydropower project in the world — that took 18 years to build and over 40,000 workers,—has sparked numerous controversies and debates regarding its impact on the environment. One of the most intriguing claims is that the immense weight of the dam's reservoir has caused the rotation of the Earth to slow down. Some scientists argue that the shift in mass could potentially affect the Earth's rotation, while other scientists neglect the belief. The Earth's rotation is influenced by a multitude of factors, including natural processes such as earthquakes and the melting of polar ice caps, making it unlikely that the Three Gorges Dam alone could significantly slow down the planet. Students will work together to complete the Doodle Notes that go along with the PowerPoint presentation. Students will hypothesis whether the Three Gorges Dam has slowed the earth. Note: This lesson supports the idea that the dam has slowed the earth's rotation and provides the scientific backing for it. Please feel free to modify this lesson to support one or the other side. ☑ For secondary — middle school and high school students ☑Check out the preview to see what is included.
