My group and I were not confused about the start of the project, but then we had trouble deciding which was first in chronological order. One thing we struggled with was when we got to the Cambrian explosion to the Permian extinction. When we had the limestone card, we thought it would either be after the cambrian explosion or before. The most confusing era was the humans, we had trouble deciding where their paths were, when the ice age happened, and hardest of all, were the evolutions, like apes to hominids, hominids to humans. I learned the paths of the humans. We solved our problems by talking about which would make more sense. For example the dinosaurs wouldn’t have come before the Cambrian explosion because the animals were still in the water.
