Enlightening Explorations, Part III
Sixth graders continue their examination of light. In groups, they make rainbows and examine the spectrum of visible light. They travel between various stations recording their observations about the behaviors of light. To end the...
Curated OER
Constructing a Spectroscope
Students construct a simple spectroscope. They observe the emission spectrum produce by a source of light.
Curated OER
Jupiter's Moons
Students predict which of Jupiter's moons will be the "brightest" in infrared wavelengths. Using provided information, they rank the moos from brightes to faintest in infrared.
Curated OER
Jell-O Optics
Students observe an activity with Jell-O to learn about optics. In this investigative lesson students fill out a handout on the activity that helps them to investigate the index of refraction and the speed of light.
Sunlight Cal-Tech
Chromatography of Plant Pigments
Through a hands-on activity, an acetone-spinach solution is pre-made and learners use this solution to separate the pigments found in spinach using chromatography. The comprehensive resource includes an analysis and conclusion questions.

Modeling Drug Assimilation in the Human Body
Students investigate the accumulation of drugs in the body. In this algebra lesson, students collect data on drug retention and assimilation. They use their data to predict the behavior and effects of drugs.
Curated OER
Stellar Fingerprints: the Spectra of Stars
Students explain how an element can be identified using emission spectra. They relate the emission spectrum of hydrogen to its absorption spectrum and identify hydrogen absorption lines in the spectrum of stars.
Curated OER
Chandra X-Ray Observatory
Students tour Chandra's top galactic X-ray images. For this Chandra X-Ray Observatory lesson, students play games and complete puzzles based on the Chandra Mission and X-Ray Astronomy. Students listen to pod casts, question an...
