Uncle Norm has decided to make a teeter totter in his back yard. It's not a pretty sight - there is no teetering, and most definitely no tottering. How can he balance it better? An architect is just the right person to help. He teaches the Rads about gravity, the fulcrum and counterweights. Will Uncle Norm's teeter totter actually work? The Gist: This episode is about another measurable property of objects – weight - and how you can measure and compare this property using specific tools and units (such as scales, which demonstrate the concepts of greater than, less than, and equal to). The concept of “balance” through equivalence is introduced.
