You teach engineering to preschoolers?

Feeling upbeat and energized from teacher training...I presented my workshop on "Engineering with Recyclables" to an appreciative, engaged group of preschool teachers. We were kindred spirits about providing children open-ended, exploratory experiences - opportunities to work on something that had no pre-ordained solution. Just looking, just thinking, just seeing, just exploring. It doesn't get more affordable than recyclables and discards!
