Reviewer Comments:

This activity, intended for middle school students and based on California Common Core Standards, asks students to classify items (part A) and organisms (part B) based on their characteristic features, ultimately representing this information visually. One thing that could be made clearer is that once items are organized “such that one group is a subgroup of the other group and both groups are subgroups of a larger group” – where do the outliers go? For example, once you are narrowed down to “pets,” where are the zebras? For this activity, teachers may want to either consider using a branching tree to classify the groups, or make the goal of the nested Venn diagram extremely clear (for example: “get ‘chickens’ to be alone in the center circle.” With a little tweaking or additional details, this is a nice introductory activity to classifying organisms.
