This nine weeks, we are studying Balance and Motion. Yesterday (and today for some), we concentrated on what makes things balance. I opened the lesson by brainstorming a list of things that balanced. We spoke of Counterweights and how humans use their arms to help them counterweight their bodies. I then showed them this clip of how gymnist balance:
The class then got to make a mobile to take home and share. On the mobile, there should be 3 vocabulary words written:
Balance: when an object stays in position on its own without being held there.
Stable: it's steady - it's not falling over.
Mobile: is a system of balanced beams and objects.
Next, I poked their curiosity as we tried to figure out how rollercoasters balance and use counterweights. I have to admit, I'm a little partial to The Texas Cyclone that used to be at Astroworld!
Questions to ponder over dinner:
What do you have to do to get a mobile to balance?
What kinds of things could you use besides pictures to make a mobile?
