Today we applied the critical thinking element "assumptions" to two videos and some real life scenarios. Bobby worked through an activity that accompanied this work, following discussion. He identified assumptions in a few minute scene of Dynamo in Miami as he amazed the passers-by with his impossible body positions. Bobby also identified his own assumptions and probable assumptions of those watching Elon Musk explain the dangers of global warming. Bobby has an assignment that requires alertness to assumptions he makes and those made by others -- and the reactions, responses, and results.
