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 a lesson about detecting atmospheres of planets. Learners will explore stellar occultation events (by interpreting light curves) to determine if an imaginary dwarf planet "Snorkzat" has an atmosphere. The activity is part of Project Spectra,... (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)

Learners will explore spacecraft radio communications concepts, including the speed of light and the time-delay for signals sent to and from spacecraft. Learners measure the time it takes for a radio signal to travel to a spacecraft using the speed... (View More)

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

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 wavelength. Students learn that a diffraction... (View More)

This is a problem-based learning activity in which students assume the roles of musicians planning a world tour. Students analyze precipitation data from tour cities to predict the best time of year to perform in these areas. Step-by-step... (View More)

Learners will create their own models of lunar orbiters out of edible or non-edible materials. They determine what tools would be necessary to help us better understand the Moon and plan for a future lunar outpost. Then they incorporate these... (View More)
