Today we had a special presentation by Dr. Flaten from the University of Minnesota. His daughters went to Brimhall and he lives in the neighborhood.
He came and shared information with us about the physics of sound. Here are some things we want to remember:
- Sound is invisible.
- Sound is represented in waves.
- Sound has a pitch - high or low.
- Sound causes vibrations.
Ask your child about the cool tools he had to measure sound and the very last thing he showed us.
