Using chroma key is a great way to transport your students across time and space. What is chroma key?
When you use chroma key, you combine two images (or videos) together by removing a specific color (or making it transparent) from the top image.
When you use chroma key, the top image includes a main character in front of a single color. You may have heard of 'blue screen" or "green screen" because of the common use of these hues.
Even if you aren't familiar with the techniques, you probably have some idea how it works already. Think about a weather reporter. They stand in front of a map that you know isn't really there. That is because the map, or background changes, and they are really standing in front of a green screen.
Using the idea of chroma key, students can become:
- explorers in a different time or place
- protagonists in their own story
- tour guides at historical sites
- part of personalize greetings
- comic book heroes
