Stellar Fingerprints and Doppler Red Shifts
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 plan.

The Doppler Effect
In 1842, Christian Doppler proposed a theory relating the change of wavelengths based on motion. Young scholars observe the Doppler Effect on a small scale in a ball, on a larger scale from a car, and on the largest scale studying the...

20th-Century Astronomy
Learners examine and explain how the distance to nearby stars can be measured by the parallax method, discuss the role of women in the history of American astronomy, form their own opinions of the importance of Harlow Shapley and Edwin...
Curated OER
Light and Elements
Here is a full-fledged investigation of light waves, the electromagnetic spectrum, and element spectra. Physicists research a scientist that contributed to our understanding of the behavior of light. They take notes on your lecture, and...

Here It Comes, There It Goes!
Students use an ordinary toy to reveal the Doppler effect. The connection is also made to moving cars, and to the shifting of the lines in the absorption or emission spectrum when the distance between a star and Earth is increasing or...

Determining Red-Shift in a Receding Star
Young scholars practice manipulating algebra formulas with more than one variable. They examine the topics of velocity, wavelength and frequency. They determine the amount of red-shift in a receding star.

Galaxies and the Universe
In this galaxies learning exercise, high schoolers review 12 terms associated with the Milky Way and galaxies in general. Students fill in the blank of 12 statements.
Curated OER
Red Shift, Blue Shift
Young scholars demonstrate how stellar spectra measures a star's motion relative to Earth along the line of sight.
