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.
It's About Time
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...

Tools to Study Tornadoes and Galaxies
Take your class on an intergalactic journey as they explore the galaxy and various meteorological events taking place in our atmosphere each day. Learners investigate electromagnetic waves and the Doppler Effect before gathering radar...

The Speed of Galaxy Q2125-431
In this speed of a galaxy learning exercise, students use a given equation for the speed of an object and they use the spectral lines for Hydrogen Alpha and Beta from the Seyfert galaxy to answer 6 questions. They determine the observed...

Galaxies
Tenth graders explore the structure and content of galaxies. Through discussion, lab, and hands-on activities, they discover the general structure of the three types of galaxies as well as the effect they have on the structure and...

Galaxies and the Universe
In this galaxies worksheet, students review 12 terms associated with the Milky Way and galaxies in general. Students fill in the blank of 12 statements.

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.

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...

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...

Learning from Light: The Big Bang
Students explore what astronomers are able to examine our galaxy and universe by examining light. They explore in this sub-unit the formation of the universe, commonly called "The Big Bang," and it follows studying from the Light: The...

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...

Simple Machines: The Wede & Lever
Students describe how wedge and lever makes work easier. In this physics lesson, students analyze experimental data by creating a graph to see the trends. They calculate the work done and mechanical advantage of these simple machines.

Chemical and Physical Changes
Eighth graders investigate different gas behaviors. In this chemistry lesson, 8th graders describe how changing volume and temperature affect gas particles motion. They collect data and make a generalization about these variables'...
