Evidence of Evolution: Embryology Activity

Get this embryology activity at a discount in our Evidence of Evolution Activity Bundle!

Challenging but fun!

In this activity, students will:

• Follow step-by-step instructions to try to match 3 different embryological stages of 6 different species (18 total cards)
• Answer follow-up analysis questions

Students clearly see that the early stages of embryonic development are very similar. This activity is engaging because it often leads students to hypothesize that a turtle embryo is a rabbit, a human embryo is a fish, etc.

This leads to high engagement and true comprehension!

• NGSS MS-LS4-1: Analyze and interpret data for patterns in the fossil record that document the existence, diversity, extinction, and change of life forms throughout the history of life on Earth under the assumption that natural laws operate today as in the past.
• NGSS MS-LS4-2: Apply scientific ideas to construct an explanation for the anatomical similarities and differences among modern organisms and between modern and fossil organisms to infer evolutionary relationships.
• NGSS MS-LS4-3: Analyze displays of pictorial data to compare patterns of similarities in the embryological development across multiple species to identify relationships not evident in the fully formed anatomy.
