Ucar: Blue Skies and Red Sunsets

Students observe the sky and weather to gather data. They conduct experiments to answer questions about the sky and weather phenomena. They measure, analyze and present data. They create sky windows by gluing sky colored paint chips...

What does a beautiful sunset have to do with the atmosphere? An inquiry-based lesson has learners make observations about the visibility and color of the sky during different time periods. They then relate their observations to...

Is the ocean blue at all depths? Nope! Explore the science behind the light spectrum in deep, dark waters. The lesson recommends watching The Blue Planet: Open Ocean—The Deep, but it's not integral, or you can substitute another clip....

Now that your science class has experimented with pH indicator and identified acids and bases, they attempt to get the cabbage juice indicator back to its original color. This is done through neutralization of the acids and bases that...

Use a container full of water as a prism and show that as light is bent, the individual colors from different wavelengths become visible. This explains why the sky appears to be blue midday, and why as the sun nears the horizon, it looks...

A hands-on simulation perfect for an economics lesson, young learners investigate the availability of different sources of natural energy (coal, natural gas, oil, solar, and nuclear) and how this availability affects their cost....

Students monitor the weather, clouds, and sky. In this weather lesson plan, students create a sky and cloud window to focus their sky observations. They write observations in a notebook and include the date, time, cloud cover, types of...

An experiment where light is shone through a bottle of water, and then milk added, to see how this affects the path the light takes (with links to articles on reflection and refraction that explain what is happening).

Learn about colors of light by exploring how prisms work. Discover the different colors of the spectrum and how the visible light is what we see.

Students are introduced to the differences between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them. They make predictions that can be answered through scientific...
