Students are asked to use a long strip of paper to construct a time line divided into two parts. The first line should show the history of technological aids used by people to observe outer space. Start with visual observation and move on to Galileo's telescope, modern observatories, space-based observatories and other important types of hardware. The second (parallel) line should show the discoveries made as better and different types of technological equipment were put to use. Take a few minutes to show and explain your dual timeline to an adult.

You are a NASA official who has been asked to prepare a prioritized list of unmanned projects as not all projects can be funded. Your list should include such things as space-based and land-based optical, X-ray, IR, UV and gamma ray instruments. Students are asked to be prepared to defend their prioritized list and budget requests before a committee of fellow students and/or adults.

Students are asked to explain the current scientific explanation for the origin of the universe.

*Evidence, Models and Explanation

Students are asked to demonstrate how to set up, align, and use a refracting telescope, a Newtonian reflecting telescope and a star finder.

*Form and Function

*Unifying Concept (NSES) represented in this activity. Unifying concepts cross curricular areas and provide students with productive and insightful ways of thinking about and integrating basic ideas that explain the natural and designed world.
