Students explore the evidence for dark matter using the measurements made by the ROSAT X-ray satellite for a small group of galaxies. Prerequisite knowledge: students should be familiar with the Law of Universal Gravitation and able to work with the... (View More) formulas for kinetic and potential energy and the Law of Conservation of Energy. This lesson is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1993 Cosmic Times Poster. (View Less)

Students predict the next discoveries that will shape our understanding of the nature of the expanding universe as they write the 100th anniversary edition of Cosmic Times. This lesson is part of the Cosmic Times teachers guide and is intended to be... (View More) used in conjunction with the 2006 Cosmic Times Poster. (View Less)

The goal of this lesson is for two groups of students to exchange information (e.g., through poster presentations, Podcasts, debates, or PowerPoint presentations) about how two different theories explain a natural phenomenon: Newton's Law of... (View More) Gravitation and Einstein's General Theory of Relativity. The lesson will also illustrate how the scientific process allows a new, more complete theory to take the place of an older theory that does not produce accurate results for a new discovery. Students will need to have either studied both Newton's Law of Gravitation and Einstein's Theory of Relativity or be given the time and resources to look up this information. This lesson is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1919 Cosmic Times Poster. (View Less)

The activity introduces students to aspects of the atmosphere, biosphere, hydrosphere, and litho/geosphere and how they are interrelated. It is designed to promote an interest in authentic investigations of Earth using images acquired by astronauts... (View More) as the hook. Separate student and teacher guides are available.

In this activity, learners replicate the scientific processes of observing, forming an explanation, revising and communicating about a model of a comet. Learners construct a model of features of a comet using an assortment of common craft supplies.... (View More) This activity relates to several NASA comet missions such as Deep Impact, Stardust, Stardust-NExT, and EPOXI and can be used to emulate a process that scientists and engineers follow on all missions.

This is an activity about the motion of the Sun, Earth and Moon, specifically rotation and revolution. After identifying what they already know about the Sun, Earth and Moon, learners will observe and manipulate a styrofoam ball model of the Sun,... (View More) Earth, and Moon system. This activity requires a location with an open space approximately ten feet by ten feet in area, and is Activity 9 of a larger resource entitled Eye on the Sky. (View Less)

In this problem set, learners will analyze an image of carbon dioxide emissions in the continental US in a given year to answer a series of questions. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to Earth Science... (View More) and Climate Change. (View Less)

In this problem set, learners will use an image of satellite-acquired ocean color data to answer a series of questions about the concentration of phytoplankton in certain areas. Answer key is provided. this is part of Earth Math: A Brief... (View More) Mathematical Guide to Earth Science and Climate Change. (View Less)

This is an activity about the size and scale of the Sun, Earth and Moon. Learners will collectively paint and label a model of the Sun and determine the comparative sizes of these three bodies. Learners can then complete a worksheet to further... (View More) explore the mathematical concepts of less than, greater than, and equal to. This activity will require various materials of specific measurements to ensure accuracy. This is Activity 3 of a larger resource entitled Eye on the Sky. (View Less)

In this problem set, learners will use a map of satellite data on Earth's surface magnetism and determine coordinates and distances for variations in magnetism. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to Earth... (View More) Science and Climate Change. (View Less)
