In this activity, students will interpret and analyze the information presented on the Evidence for Hidden Mass graph. They will observe trends in the graphs, and use it to determine if there is evidence for hidden mass. This is Activity 6b in the...

In this activity, students use rulers to measure distances between hypothetical galaxies and then use these distances to calculate the velocities of the galaxies. This activity is part of the "Cosmic Questions" educator's guide that was developed to... (View More) support the Cosmic Questions exhibit. This activity can be in conjunction with, or independently of, the exhibit. (View Less)

In this activity, students work in groups to create a presentation that illustrates the meaning of the statement "To make an apple pie from scratch you must first invent the universe." Students pick an element that can be found in apple pie and... (View More) trace its evolutionary history back to the birth of the universe itself. They also share their vision of the environment in which that element may find itself 5 or so billion years from now after the Earth is long gone. Presentations are intended to demonstrate student understanding of the origins and life cycle of matter, so this activity is appropriate as a conclusion to a unit. This activity is part of the "What is Your Cosmic Connection to the Elements" information and activity booklet. The booklet includes teacher notes, grading guide and student handouts. (View Less)

In this activity, students use a piano keyboard to model spectral lines as musical chords. It is designed to aid student understanding of spectral analysis, what the patterns mean, how elements are involved, and how this relates to stars.... (View More) Traditionally, spectral images are two dimensional, and related to text. This auditory activity allows students to "hear" differences in patterns of various elements (e.g., nickel or helium). This activity is part of the "What is Your Cosmic Connection to the Elements" information and activity booklet. The booklet includes photos, teachers notes and instructions, and a link to a color image pdf of visible light spectra that can be printed and used to do the activity. This activity requires a piano keyboard, color printout or construction paper and/or toothpicks (to mark spectral lines of elements). (View Less)

Traditionally, spectral images are two dimensional, and related to text. This kinesthetic activity has groups of students position themselves along a printed spectrum to make spectral patterns and model various elements. Includes photos, teachers... (View More) notes and instructions, related resources (e.g., color pdf of a visible light spectra image that can be projected onto a white board or wall to do the activity), and alternative suggestions.
