Reflection about Unit Conversion "Fun" Movie
To make unit conversion "fun" our group made a video about a "Measurement man" who taught scientists designers architects and engineers how to measure with the same unit so that they would agree with each other and be able to display their work in units that they could all comprehend.
We were definitely reminded of measurements while facing the challenge of trying to make it fun. Finally, we came to the conclusion that we could make a short film in which a superhero would save the day by using measurements and the correct units.
