Data collection sheets are used by students to record visual and tactile observations. These data sheets provide a structured mechanism by which children organize their observations. Betty stresses the importance of accurately applying the skill of communication. Mechanisms for making representative drawings are an important part of the activity.

Attention is called to a group of children who discover a creative way to measure their shells.
Other students also adopt their idea. The teacher stresses importance of communicating using correct metric units. An additional feature of instruction is the way Betty used a creative classroom management technique to redirect student behavior during science activities. Children are introduced to the skill of classification. Using their recorded data, they are asked to develop binary classification systems.
