In the presentation by Sara Lacy at the Energy Summit I
really liked the subtle distinction Sara described associated with the energy
story of a person (Jim) rolling a ball. We
might assume that if learners understand that, Jim has energy, the ball gets
energy, and Jim caused the ball then it would be obvious to them that Jim gave
the ball some of his energy. Sara suggested that this last point is not an obvious leap for 3rd grade learners. When a marble strikes a
stationary marble, it is may be clear that the motion energy of the first marble
decreases. When a person rolls a ball it
is not nearly as clear that the energy of the person decreases in the
process. As we develop energy learning progressions for young
learners it will be necessary to really listen to them so that we can understand
some of the unanticipated places where they will experience cognitive
challenges.
