This is an activity during Solar Week, a twice-yearly event in March and October during which classrooms are able to interact with scientists studying the Sun. Outside of Solar Week, information, activities, and resources are archived and available... (View More)

In this lesson students investigate the effects of black carbon on arctic warming and are introduced to a mechanism of arctic warming that is not directly dependent on greenhouse gases in the atmosphere: black carbon deposition on Arctic snow and... (View More)

In this activity, student teams will create a controlled experiment by building ecosystems in two 2-liter bottles. Teams determine the control conditions of both bottles, identify a test variable, and run the experiment for several weeks to... (View More)

In this lab activity, student teams hypothesize which source has a greater becomes CO² concentration: their breath, auto exhaust, or air in the classroom. They test gas samples from each of these sources, plot data, and hypothesize about the... (View More)

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 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)

In this activity about magnetic fields and their relation to the Sun, learners will simulate sunspots by using iron filings to show magnetic fields around a bar or cow magnet, and draw the magnetic field surrounding two dipole magnets, both in... (View More)

This is a lesson about the shape of objects in space. Learners will observe the surface of rotating potatoes to help them understand how astronomers use variations in reflective brightness to determine the shape of asteroids.

In this laboratory activity, students observe what happens when a fluid of one density is placed in a fluid of a different density. The fluids are salt water and fresh water, cold water and warm water. They generalize their results to describe what... (View More)
