In this activity, students are reminded that the Universe is made up of elements and that the heavier elements are created inside of a star, as they learned in the "Elements and You" activity. They are introduced to the life cycle of a star and to... (View More) the way in which a star's mass affects its process of fusion and eventual death. Students discuss the physical concept of equilibrium as a balancing of forces and observe an experiment to demonstrate what happens to a soda can when the interior and exterior forces are not in equilibrium. An analogy is made between this experiment and core collapse in stars, to show the importance of maintaining equilibrium in stars. Finally, students participate in an activity which demonstrates how mass is ejected from a collapsed star in a supernova explosion, thereby dispersing heavier elements throughout the Universe. This activity is part of a series that has been designed specifically for use with Girl Scouts, but the activities can be used in other settings. Most of the materials are inexpensive or easily found. It is recommended that a leader with astronomy knowledge lead the activities, or at least be available to answer questions, whenever possible.

This manual provides simple demonstrations to show how lenses and mirrors are used to create telescopes. It was created for use by the Night Sky Network of astronomy clubs.
This activity includes twelve monthly star charts to identify the stars that are visible in the night sky and that are known to have planets around them. The star maps can be used to find constellations and identify stars with extrasolar planets.... (View More) (Northern Hemisphere only, naked eye) (View Less)
This manual provides an overview of how telescopes have changed our understanding of the universe and contains simple demonstrations to use at star parties to get across basic ideas of optics. This manual will also help explain why the images that... (View More) folks see at the eyepiece of a telescope at an outreach star party is so different from images published in magazines. The manual was produced to accompany an outreach toolkit developed for the NASA Night Sky Network. The toolkit is no longer being manufactured, but the activities are available through the manual, which can be freely downloaded. (View Less)
This is an activity about measuring angular size and understanding the solar and lunar proportions that result in solar eclipses. Learners will use triangles and proportions to create a shoebox eclipse simulator. They will then apply what they learn... (View More) about angular size to predict the diameter and distance of one object that can be eclipsed by another. They will also complete three journal assignments to record observations and conceptual understanding. This activity derives from those demonstrated in the NASA CONNECT television series episode, titled Path of Totality. (View Less)
In this activity, students experiment to test the hypothesis that Mars was once hotter. The activity requires some advance preparation by the teacher: the day before the activity, need to place a plastic bottle filled with water in the freezer.... (View More) Materials needed include plastic bottle of water and thermometer. It is a companion piece to a CD about the exploration of Mars that uses song and drama to tell the story of Spirit and Opportunity, NASA's Mars Exploration Rovers, and their mission to search for signs of ancient water.
