This was an excellent lesson plan! It was well organized and clearly laid out. It also has all the resources that a teacher would require to use the lesson. The creator has stated exactly what needs to be done before an during the lesson. The creator has also listed possible extensions for the lesson as well as homework and an assessment. I like how this assignment is interactive. It is a great way for students to be introduced to evolution! My middle school students will love how a story goes along with the assignment. I also like that the assignment is inquiry-based. So the students have to use their clues to decide where the whales go along the geological timeline.
