This is a lesson about using light to identify the composition of an object. 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... (View More)

This is a lesson about elemental spectra. 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... (View More)

This is a lesson about emission spectra. 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... (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)

This is an activity about the period of the Sun’s rotation. Learners will select images of the Sun from the SOHO spacecraft image archive. Next, they will calculate an image scale for the selected solar images. Then, they will use it to help... (View More)

In this hands-on activity, students analyze the data on Mystery Object Cards, observe that astronomical objects have many observable properties, and discover that these properties allow scientists to categorize astronomical objects into different... (View More)

This activity is intended as a review of the concepts presented in the previous activities as well as an assessment of student understanding of the activities. Learners use the review information from the activities as they answer question and then... (View More)

In this activity, learners classify selected objects from the Hubble Deep Field based on their color and shape. They then compare their classification with a chart made by astronomers. This is activity two of four in the Hubble Deep Field Lesson... (View More)

In this activity, the problems and difficulties of determining the distances between Earth and objects in space is addressed. Learners attempt to arrange five objects from the Hubble Deep Field according to their distances from Earth. After making... (View More)

This is an activity about observing. Learners will look for particular stars, their colors and brightnesses, as well as important constellations in the nighttime sky. They also will compare the relative brightness of the sky near towns to gauge the... (View More)
