Science Club with the "Flipped Classroom"

Due to the COVID-19 pandemic, we are doing Science Club remotely via Zoom on Friday afternoons.

Using the "flipped classroom" approach, children and their families are doing several science experiments at home prior to the class meeting. I love that families are able to hang out and do these activities together! Then we gather in the Zoom room and discuss the results of their experiments and I share some demonstrations and questions. It was fun and very successful!

Building upon our activities last week in Science Club, we are doing an exploration of Sound.

Friday, March 20

Prior to Meeting

• #1 - "Determining the Different Sources of Sound," page 41
  from Physics is Fun! by Roberto Trostli
  
• #2 - "Mystery Sounds," page 42
• #3 - "Grouping Sounds into Categories," page 42
• #19 - "The Propogation of Sound through Solids," page 51
• #22 - "Underwater Sounds," page 52
• Design Challenge - DIY Phone Speakers

  some possibilities: a glass, a ceramic mug, a styrofoam cup, a bowl, a paper towel tube, etc.

  Find something curved or tubular and place a cell phone (which is playing music) inside of it. What happens? What material or design works the best?
