Episode 805: The Bluebird of Zappiness

To embarrass Hacker, Ledge sets out to find the key to cure Motherboard, and Hacker is forced to team up with the kids and use ‘shadow math’ in Groundhoggia to unravel clues to stop him.

For Real segment: Harry and Harley find a wad of cash on the sidewalk and use some photos they took, plus shadow math, to figure out the rightful owner and return the money.

Learning Goals

When your child knows the height of an object, she can use the length of its shadow to figure out the height of something else – even if it is too tall to measure directly.

Topics: Pre-Algebra, Measurement, Measuring Shadows to Find Height
