This week, as part of our science study of waves, we had a special guest speaker come in and show us some really cool information about sound waves. Mr. Keenan made a visual representation of sound waves using computer imaging (because we can't see real sound waves). He also put some packing peanuts on a speaker to demonstrate the powerful vibrations from the sound waves that made the peanuts dance to Justin Timberlake's "Can't Stop the Feeling"!
Mr. Keenan then passed out tuning forks to house tables so we could explore making sounds and seeing the effects of the vibrations in a dish of water. If you held the tuning fork to the edge of the metal water dish, it made an interesting buzzing sound as the metal vibrated. Kids couldn't wait to get their hands on the materials to experiment themselves. We are really looking forward to another visit from Mr. Keenan next week!
