Curated OER
Simple Machines: The Wede & Lever
Students describe how wedge and lever makes work easier. For 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.
Curated OER
Super Gelatin
Students investigate the refraction properties of gelatin to calculate its index of refraction. They discover that as the light travels through the gelatin, its speed and wavelength also change. Students find th indes of refraction of an...
Curated OER
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...
Curated OER
Waves, Sound, and Light
Ninth graders explain waves in terms of energy transfer and describe their basic types and characteristics. They solve mathematical problems involving wavelength and frequency. Students conduct experiments in reflection and refraction.
Curated OER
Reading the Waves
Students view video segments which reveal the parts of sound and what factors control sound. The viewing and post-viewing activities serve to reinforce the video segments using worksheets and hands-out experiments.
Curated OER
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...
Curated OER
How Do The Colors of Light Mix?
Students investigate the mixing of light. They form a hypotheses to reason why color changes occur and they write conclusions and ask new questions arising from the investigation. Students identify the primary and complementary colors of...
Curated OER
Galaxy Mapping
Learners 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.
Curated OER
Wind and The Airline
Fifth graders attempt to solve a problem related to an airline accident. The accident appears to be weather related. They analyze and research the effects of wind and turbulence in order to prevent future accidents.
Curated OER
Red Shift, Blue Shift
Middle schoolers demonstrate how stellar spectra measures a star's motion relative to Earth along the line of sight.
Curated OER
Sound Waves; vocabulary review
In this science learning exercise, students locate 28 words in a word search. The focus of the word search is vocabulary connected to the study of sound waves.
Curated OER
E3 Project Instructional Plan: Light
Eleventh graders investigate the nature of light. In this physics lesson, 11th graders determine how light intensity varies with the distance of the light source.
