Science+8

There is going to be a final exam for Science 8 and YOU get to decide what questions will be on this exam to show how much you have learned throughout the year. Your mission, if you wish to take it, is to demonstrate major ideas that you have learned in the Science 8 course through an online collage. You may use Youtube videos, key terms or questions, pictures, diagrams, animations, website links, tables, etc.

What to do?
 * 1) Once you have reached this section of the Wiki, the Science 8 section, you can add any evidence of what you have learned by simply clicking on the **EDIT** link.
 * 2) The **"Editor"** bar will appear at the top of the window.
 * 3) Using various resources (ie. textbook, binder, the Web), add some form of **evidence** that you have learned something in Science 8. See the 2 examples I have included below.
 * Be sure to press **ENTER** to add your artifact on a new space. In other words, avoid erasing title headings or any other students' artifacts.
 * You may add as many **artifacts** as you want.
 * 1) After you have added your artifact, you must also include either of the following:
 * A **statement** about your artifact that demonstrates "What have you learned?"
 * A **question** that relates to your artifact that other students might be able to answer.
 * 1) Please leave your name below your work. Use only your first name and last initial (ex. Mike D.). DO NOT USE YOUR FULL NAME.
 * 2) And of course, press **"Save"** in the Editor bar.

Optics
amanda D <3

In optics, a **prism** is a transparent optical element with flat, polished surfaces that refract light. The exact angles between the surfaces depend on the application. The traditional geometrical shape is that of a triangular prism with a triangular base and rectangular sides, and in colloquial use "prism" usually refers to this type. Some types of optical prism are not in fact in the shape of geometric prisms. Prisms are typically made out of glass, but can be made from any material that is transparent to the wavelengths for which they are designed. A prism can be used to break light up into its constituent spectral colors (the colors of the rainbow). Prisms can also be used to reflect light.
