Sounds like fun…

to make your own smart phone speaker!

That’s what we did today in Full STEAM Ahead. Using just a paper towel tube, two paper cups, and some paper towels (and some pretty paper), we made speakers for our phones–or for someone else’s for those who don’t yet have their own phone.

We learned about sound waves and played a “What’s that sound” game, too.

Here are some photos.
