Determining Red-Shift in a Receding Star

Young scientists observe the spectra of elements and compare that to the Doppler effect. Hook scholars from the beginning all the way to the extension activities in this 5E-format lesson. 

Stars exist from a few million years to over 10 billion years, depending on their mass. Scholars perform a play acting as stars to learn about their different life cycles. They develop an understanding of many of the fundamental concepts...

The Red Shift concept can be one of the most confusing in physics. Learners may find it helpful to start with learning more about the Doppler Effect before introducing this video.

First, Sal defines consistent and inconsistent equations. He then evaluates a system of linear equations to determine if they are consistent or not. This resource isobviousr and would be a wonderful video to show before a test or at an...

Star light, start bright! What do the brightness and color of stars tell us about the stars we see at night? Learners explore the life of stars with an information-packed video. Topics include the relationship between mass and...

Learn about gamma rays and red shift, what they are, what they mean, and how scientists use them to measure distances between objects in space. This clip explains how important red shifted gamma rays are to science and how illusive they...

Let the class stars shine. Using four given linear equations, scholars create a graph of a star. The pupils use the interactive to graph the linear systems and determine the points of intersection. Through the activity, classmates...

Seven real-life math problems require the solving of simultaneous pairs of linear equations. Although a similar approach is taken for most of the problems, the topic of sports stadium concessions should keep the interest level high. As a...

The history of our understanding of the center of the universe is explored through this film. The ideas of Aristotle, Copernicus, Bruno, Descartes, and Herschel are included, as well as the new discoveries that have helped the theories...

Aspiring astronomers study stars. They compare stars and explain the relationship between radius, mass, and diameter. By creating a star simulation, they discover how a binary star system's orbit can cause changes in the observed...
