Absorption of light in water

Water absorbs light. Red light is swallowed first, then other parts of the light spectrum. From about one kilometer, no more light penetrates into the depths. Authors: ZDF/Terra X/Hanna Kotarba/renderbaron Translation and dubbing: alugha Click here to see more videos: https://alugha.com/TerraX

Light Sources

Explore natural and human made light sources in the environment in this live-action video produced by WGBH. The video can help children observe and identify light sources and describe objects that are visible in the light’s path. Support materials include: Background Reading, Teaching Tips, and Dis

Communicating with Light

Observe a group of children using light to communicate over a distance in this live-action video produced by WGBH. Use the video to observe strategies for using light to communicate across a distance as well as to design a light signal code to help you communicate to solve a problem from different l

How is wind created?

When air is in motion, wind is created. Temperature differences are responsible for this. When air warms up, it rises and colder air flows in. This is the cool wind that we feel. There is almost always wind on the coasts. Author: ZDF/Pur+/Autorenkombinat/Tobias Schönke/Carina Schulz/Jochen Schmidt

How does a wind turbine work?

Wind turbines use the energy of the wind and convert it into electricity. In doing so, they use the physical principle of buoyancy. Author: ZDF/Pur+/Autorenkombinat/Tobias Schönke/Rita Gerhardus-Faust/Jochen Schmidt Translation and dubbing: alugha Click here to see more videos: https://alugha.com

Dangerous winds at Cape Horn

Patagonia is notorious for its extreme winds. At the tip of South America, very cold air masses from Antarctica collide with warmer air from the north. Heavy storms rage at the southern end of the continent 300 days a year. Author: ZDF/Terra X/R.Marel/S.Hillmann/C.Gerisch/A.Kindler/SpiegelTV/Maximi

Energy-Efficient Lighting

This video highlights the importance of energy-efficient lighting. Energy efficient lighting is necessary to reduce electricity consumption and to lower greenhouse emissions. Every household, business and institution can contribute by replacing fixtures with energy efficient bulbs to save electricit
