Experiment 1: Classification of Common Objects
Questions
1. Did you find that the items grouped together as you worked down the flow chart had similar characteristics in terms of their appearance? What about function?

2. Do you feel that the questions asked were appropriate? What questions would you have asked? What objects would be grouped together with your system?

3. Pick 10 household items (e.g. spoon, book, paper clip, etc.) and design a taxonomic classification system to categorize them, similar to the one in Figure 2.

4. Can you devise a different classification system for the objects used in this experiment that would distinguish each in as many, or fewer steps?
