This is a lesson about visual spectra. Learners will explore different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or... (View More)

Learners will build an open spectrograph to calculate the angle the light is transmitted through a holographic diffraction grating. After finding the desired angles, the students will design their own spectrograph using the information learned. The... (View More)

Students are introduced to the periodic table and the concept of atomic elements. The group discusses how all material in the Universe is composed of elements and that the atom is the smallest particle that still has the physical and chemical... (View More)

In this problem-based learning activity, learners investigate impact of sulfur dioxide on the environment. Sulfur dioxide comes from both human activities and natural sources. Burning coal and other fossil fuels is the largest source of sulfur... (View More)

In this problem set, learners will answer a series of questions about the complex molecule, Propanal. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to Earth Science and Climate Change.

Audience: Elementary school, Middle school
Materials Cost: Free

In this activity, students devise ways to demonstrate that energy can change from one form to another in accord with the law of conservation of energy. Small appliances, toys, marbles, vinegar and baking soda, simple electrical supplies available... (View More)

Audience: High school
Materials Cost: $1 - $5 per group of students

This is a video to accompany the Stanford Solar Center's Build Your Own Spectroscope activity. It serves as an introduction to several aspects of the Sun, including information about solar activity, effects of solar activity on Earth and other... (View More)

Students use a calorimeter made of common materials to demonstrate that energy can be measured and converted from one form to another. Hydrocarbons, such as paraffin, contain stored chemical energy; food contains stored chemical energy. The activity... (View More)

These two hands-on labs are about the role of temperature and salinity in governing the density of seawater, a major factor controlling the ocean's vertical movements and layered circulation. In the first activity students work in groups to... (View More)

In this activity, students will use a simulator of an orbiting X-ray observatory to observe a supernova remnant, the expanding gas from an exploded star. They will take X-ray spectral data, analyze them, and answer questions based on that data. This... (View More)
