In grades K-2, students are at an age when they start to look closely at living things around them. They can comprehend that while individuals may be of the same kind (i.e., kittens from the same litter), they possess differences. This article uses the learning cycle to engage students in making observations and measurements about plants and animals in order to help them understand “there is variation among individuals of one kind in a population” (AAAS, 1993, p. 107). This article promotes National Science Education Standards A and C, and Iowa Teaching Standards 1, 2, 3, 4, 5, and 6.
