Learners will compare known elemental spectra with spectra of Titan and Saturn’s rings from a spectrometer aboard the NASA Cassini spacecraft. They identify the elements visible in the planetary and lunar spectra. The activity is part of Project... (View More)

Learners will use a spectrograph to gather data about light sources. Using the data they’ve collected, students are able to make comparisons between different light sources and make conjectures about the composition of a mystery light source. The... (View More)

Learners will interpret spectral graphs to determine the atmospheric composition of Earth, Venus, and Mars, and then mathematically compare the amount of the greenhouse gas, CO2, on these planets. Students will brainstorm what things, along with... (View More)

This is an activity about detecting elements by using light. Learners will develop and apply methods to identify and interpret patterns to the identification of fingerprints. They look at fingerprints of their classmates, snowflakes, and finally... (View More)

Learners will look at various light sources (including glow sticks and Christmas lights) and make conjectures about their composition. The activity is part of Project Spectra, a science and engineering program for middle-high school students,... (View More)

Learners will build and decorate their own spectrographs using simple materials and holographic diffraction gratings. After building the spectrographs, they observe the spectra of different light sources. Requires advance preparation to spray-paint... (View More)

Activities in this lesson promote a fundamental understanding of relationships between graphed data. Sample graphs allow students to become familiar with interpreting data and to recognize relationships between variables. Additional microsets of... (View More)
