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 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)

This is an activity about size and scale. Learners will create and walk through a distance scale model of the size of the Solar System. This activity requires a straight line distance of approximately 295 meters (300 yards).

Audience: Elementary school

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)

Students are introduced to the scientific tool of spectroscopy. They each build a simple spectroscope to examine the light from different light sources, particularly the Sun (Warning: Do not look directly at the Sun) and artificial lights (e.g.,... (View More)

Students are introduced to the basic properties, behavior and detection of black holes through a brief discussion of common conceptions and misconceptions of these exciting objects. They "act out" a way black holes might be detected through their... (View More)

This lesson uses a simple discrepant event to demonstrate the underlying cause for early miscalculation of the size of the Milky Way galaxy. By standardizing the Cepheid period-luminosity relationship without recognizing there were two types of... (View More)

Materials Cost: $1 - $5 per group of students

In this lesson, students consider observations and inferences to determine the support for each of two theories on the origin of the universe: Steady State and Big Bang. Working with partners, students draw from a set of Evidence cards (master is... (View More)

In this lesson, students will investigate the Doppler Effect and discover how the same principle can be used to identify a possible tornado in storm clouds and investigate the rotation of distant galaxies. Students should be familiar with the... (View More)
