1. Have students write a short, fiction story that utilizes or explains physics concepts as part of the story. I was also thinking that they could take a science fiction movie or story and address the physics of the movie (real vs. fiction.).
2. Write a song, poem, or rap about a physics concept as a great study aid.
3. Write/create/blog/wiki/poster/presentation applying physics to music, art, etc. One example would be the physics of light and color related to art, or the physics of sound related to their favorite instrument.
4. Create/write/blog/wiki/presentation about how a scientific discovery or new technology has changed the world and history.
I also realized that these types of projects can integrate 21st century skills and technology skills and will definitely be more interesting than a lecture. Students will learn alot and have fun.
