Test, Observe, Revise: Engineering with a Preschooler

The slow-motion video option on my phone has captured my preschooler's attention lately, so we are using it to improve our marble track engineering.  When we record a run in slow-motion and review it, he can more easily see where problems occurred in our design and come up with potential solutions. He also really likes … Continue reading Test, Observe, Revise: Engineering with a Preschooler

Boundless Energy: Awesome Preschool Science Activity

This week, our marble set has been working overtime.  We engineered a wall of pipes and tracks to run our marbles down, and we've been using it to explore how potential and kinetic energy work.  We began with a short track at the base of the wall and tested  marbles to see if they had … Continue reading Boundless Energy: Awesome Preschool Science Activity
