Reading in the Dark

We know the speed of light, but can we measure the speed of dark? During the lesson, scholars perform gedanken, or thought experiments related to the speed of sound and the speed of light. 

Explore the behavior of light with different materials. Collaborative groups determine whether certain materials absorb, reflect, diffract, or transmit light waves. They then measure the angle of incidence and angle of reflection.

How does the color of the sky change from blue to reds and oranges to black? An illuminating lesson explains how light travels through different mediums using the sun's light as an example. By examining diagrams and illustrations, pupils...

An illuminating activity demonstrates how interference of light waves creates a pattern. Using Plexiglas™ and construction paper, participants see rainbows appear as they twist or press against the plastic plates. After the activity, you...

Let Einstein's work shine the way. Pupils read about Einstein's iconic equation, E=mc^2, using a remote learning resource and see how ideas from other scientists such as Kepner, Curie, Galilei, and Newton led to its discovery. They...

Students examine the relationship between solar activity and the Earth's geomagnetic field in producing the phenomena known as aurora borealis (Northern Lights) by reading and discussing "Earth, Wind and Fireworks." students graph data...

How can nocturnal animals see at night? Bigger eyes? More photoreceptors? Use this video to discover the amazing ways animals have adapted in order to see at night.

Turn misconceptions into learning opportunities. A video PD lesson from the Good Thinking series reviews common misconceptions pupils develop when learning about photosynthesis. A professional development guide offers a format for...

Just how big is the galaxy? Learners read information about the size of the Milky Way galaxy to better comprehend its size. Pupils develop an understanding of the number of stars in the galaxy by finding just how big a billion is and...

Carve out some time to learn about space-time. Young scientists use a remote learning resource to read up on the relationship between space and time. They consider the idea of relativity, see how objects with a large mass can bend space...
