One of These Things is Not Like the Other

Learners use a Microviewer to examine common objects at 60-100X magnification. After viewing these things, learners categorize them according to their properties. They create a game board to challenge other learners to identify which item doesn't fit with the others according to their properties. With minor modifications, this activity is appropriate for young learners as well.
