After working with Jules this morning, we created our own dichotomous keys. First, we did one as a group to categorize four objects; an apple, a banana, a clementine, and a pack of Sour Patch Kids. We were only allowed to classify things based on observable physical characteristics. For example, color, shape, or size, as opposed to "delicious," or other subjective terms.
After a discussion, everyone was tasked to make a key of all the kids in our class.
