#### Scale of the Universe 2: A Website for Earth-Space Science

Summary : The universe up close and from afar!

The Scale of the Universe 2 provides users with a tool for viewing their environment close up and also from a distance. To begin, users must load the website and pick their language. Next, the website loads a screen with instructions on it. After reviewing the instructions, users can click the “Start” button to begin their journey. The website will then open a new page, and users can begin viewing their environment up close or from a distance by moving the slide button on the bottom. As the button is moved to the left, the environment is magnified. As the button is moved to the right, the view moves to a distance. The scale is on the bottom right of the screen, and 10 is the human’s perspective of the universe. As the slide button is adjusted, users can view the exponent above the 10 increase or decrease.

### Instructional Ideas

1. Teachers can allow students class time to use this website. While using it, teachers can have students record 3-5 general ideas they learned from the experience. Students can post their ideas to a class website, or teachers can use them to begin a class conversation. To do so, teachers can ask: (1) What did you notice as you magnified the environment?, (2) What did you learn when you viewed the environment from a distance?, (3) If you could live at any “size” based on this scale, what size would it be?
2. Teachers can have students use this website to compare the size of two or more objects and have them arrange those objects from biggest to smallest. For example, teachers can have students compare the size of an ant, the largest bacteria, and a dust mite. Students would have to put them in order. The purpose would be to demonstrate to students how small objects are as compared to one another.
3. After becoming familiar with the functionality of this website, teachers can have students place additional objects on the scale, such as a one-cell animal, a quasar, and one of the great pyramids. To explain where they rank, students can list the object they placed along with the scale size. (The scale size is the number on the bottom right of the screen.)
