This is an activity that compares the magnetic field of the Earth to the complex magnetic field of the Sun. Using images of the Earth and Sun that have magnets attached in appropriate orientations, learners will use a handheld magnetic field... (View More)

In this hands-on activity, students learn about the different realms of the Universe and explore their sizes and relative scales. They will be guided through a process that uncovers the immense sizes of the Sun, Solar System, Solar Neighborhood,... (View More)

Keywords: NSTA2013

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 math-science integrated unit about spectrographs. Learners will find and calculate the angle that light is transmitted through a holographic diffraction grating using trigonometry. After finding this angle, the students will build their... (View More)

Audience: High school

This is a lesson about determining planetary composition. Learners will use a reflectometer to determine which minerals are present (from a set of knowns) in a sample of Mars soil simulant. Requires the use of ALTA II spectrometers (which may be... (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)

This is an lesson about spectrographs. 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.... (View More)

This is an activity about observing and mapping sunspots by direct solar observation. Learners will use a small telescope, binoculars, or a Sunspotter to create a projected image of the Sun and trace the position of any observed sunspots on a piece... (View More)

This is an activity about photosynthesis. Learners will use the basic principle of photosynthesis and investigate how light intensity diminishes as a function of distance from the light source. Questions help them connect these two ideas to... (View More)

This is an activity about critical observation skills. Learners will receive an egg to record its features from various vantage points, illustrating their size, shape, and location. They will then try to identify and recognize the surface features... (View More)
