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.

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...

The Doppler Effect Lab
In this Doppler effect worksheet, middle schoolers read information about the Doppler effect. Students answer questions as it relates to the pitch and wavelengths of a demonstration simulates what happens with the Doppler Effect.

Doppler Effect Worksheet
In this Doppler Effect worksheet, students answer questions about the movement of stars and the reason we see differences in the color of the stars resulting in a red shift or a blue shift.

Determining Red-Shift in a Receding Star
Students 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.

Singin' the Black and Blues
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...

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...

Red Shift, Blue Shift
Middle schoolers demonstrate how stellar spectra measures a star's motion relative to Earth along the line of sight.

Modeling the Big Bang Theory
Young astronomers learn about the Big Bang Theory and redshift through a hands-on activity in the last installment of a three-part series. Participants draw dots on balloons and then inflate them to model how galaxies moved farther apart...

Galaxy Mapping
Young scholars research the constellations and discuss their findings. Then they construct their own maps of the galaxy using paper, black paint, aluminum foil, etc. They make a 3-D map of their chosen constellation.
