SINGING WINE GLASS/DANCING FORK/AMAZING FORK
Scientific Principles:
- Sound Waves: a wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air
1.) What was the point of this activity?
Sound waves create vibrations and can be heard as long as it travels through a pathway
2.) Explain how you would introduce this to your class.
Playing a video of an opera singer breaking a glass with his/her voice
3.) Where do you see a student having difficulty with this?
Not understanding why tracing the rim of the wine glass makes a noise
4.) What changes or extensions could you do to this activity?
Asking the students to go home and see what sounds they can make with things that they find around their house
LIGHT BOX ACTIVITY SHEET
Scientific Principles:
- Reflection: The change in direction of a wave, such as a light or sound wave, away from a boundary the wave encounters. Reflected waves remain in their original medium rather than entering the medium they encounter
1.) What was the point of this activity?
Based on the tilt of the mirrors, you’ll get different light rays and they’ll go in different directions.
2.) Explain how you would introduce this to your class?
Bring mirrors into the classroom and ask students how they are able to see their reflection.
3.) Where do you see a student having difficulty with this?
Not understanding why the different mirrors are producing different rays when they are technically the same material.
4.) What changes or extensions could you do to this activity?
Show how a flashlight reflects glass or a mirror.
