We began our science unit about sound almost as soon as we returned! I was so excited to be teaching this new unit that I didn't even take any pictures this week! Our supervisory union's science coach was here to co-teach and Ms. Konowitz and I taught the unit together.
Our unit began with a video of a glass breaking! A man was making his voice very loud and the glass broke! He starts to hoot and holler right after the glass breaks so I hit "pause"!
I asked the children to see if they could explain why that happened. Lots of interesting and thoughtful (but wrong) answers. They explained that his voice put so much air into the glass that it broke-like a balloon. They explained that his voice was pushing on the glass and that broke it. They explained that it was just so loud and loud noises break glasses. We explained that we'd be performing some investigations over the next few days and after learning more, they WOULD be able to explain why the glass broke. It was a great way to start the unit!
Then they used various items to make sound and learn that sound makes vibrations. We then provided them with things that vibrate to determine if they also make sound. They tried tuning forks...
...and drums and cymbals...
...they had lots of time to experiment, but also they spent time collecting data so they could make scientific claims. It was a fun unit and hopefully if you ask your child about it, they can tell you all about sound and vibrations!
