Seventh grade Lesson Evidence for Evolution

evidence of evolution activity answer key

Essential concepts: Evolution, fossil record, molecular homologies, homologous structures, embryology, vestigial structures, primates. To close day 2 of this lesson, I distribute the , and have students complete this individually. As it is playing, I have students that were recorders the day before get their computers, and distribute the evidence charts to today's recorders. This is one of the things I really like about using this website, as it provides clear explanations that the students can follow, and allows them to make connections between the different lines of evidence observed. How does this structure provide evidence for evolution? As much as possible, allow students to determine, state, and research their own clarifying questions. Only certain birds can feed on these flowers, and the flowers can be pollinated only by certain species of birds.

The recorder will then write their agreed upon answer on the evidence chart. The picture shows examples of the different beak types Darwin observed on the finches of the Galapagos Islands. The results of this interim assessment let me know how much support the students might still need during the next lesson. I then tell the students that today we will begin to explore the evidence we have for evolution, and play Stated Clearly's movie,. Convergent evolution has selected for the particular traits that allow both these species to be best suited for their environments. I quickly realized that my two day activity was one that students were extremely interested in pursuing more substantively and that they wanted time to create representations of their learning that required more collaborative time.

This can also relate to anatomical homology. This year, most students took 1. How have sharks and dolphins been affected by convergent evolution? Embryology is the branch of biology that deals with the formation, early growth, and development of living organisms. As students come in for the second day, I play the Symphony of Science's video. When I started it, my intention was to give students a brief opportunity to investigate a science concept on their own that I felt was one they could grasp without a large amount of teacher support or prior knowledge. Evidence of Evolution Worksheets The evidence of evolution worksheet set is a series of diagrams and short activities to illustrate each of the major types of discoveries that support evolutionary theory.

It also helps us understand how far back in time each species has been around. I was very proud to see them attend to these guidelines even without specific instructions to do so. How does having a common embryology serve as evidence for evolution? Homologous structures develop in the embryo just like any other structure, therefore organisms that develop in a similar way are more likely to have homologous structures. I tell students that they will be working with their elbow partner, and instruct students to the right to gather their computers. I do this to allow students the opportunity to continue their exploration at home on their own as many of them choose to do.

This activity is one I have been working with for a few years now. Sharks are fish, and dolphins are mammals. This relationship indicates these species have undergone coevolution. Just in case there was a group who was really committed to specific high level graphics on their posters, I extended their poster deadline on an individual basis. Once the music stops, I tell students that they will continue the previous day's work, and that it must be finished by the ten minute bell.

How did these finches arrive in the Galapagos Islands? Point out the expert group area locations around the room, one evidence type for each corner of the room:fossil record, comparative anatomy, comparative embryology, and molecular biochemical evidence. The next pieces of evidence comparesembryos of different stages of chicken, human, fish, turtle, salamander, and rabbit. I have outlined my typical plan for each day, but keep in mind that every class is different and you may need to adjust a bit each day. The goal is for each student to be ready with their individual research in order to dig in deeper with their expert group tomorrow before moving back to their lab groups and presenting their findings. As the class session comes to an end, ask students to return to their desks and leave their lab table areas tidy. This four day iteration seems to work best.

The functions of the structures are different as a result of the environments in which the organisms live. The fact that they look similar is a coincidence due to living in the same type of habitat. See this typical for an idea of what students will write about their topic area. Ask students to check in together briefly to determine homework expectations for that evening. I also felt the end of the final school grading session was a great time to shift away from the lecture framework because at that point, even a 15 minute teacher centered session was getting to be challenging for students ready for summer break and a bit bored by the routine of their school day. Tell students that this week, they will be doing an activity to learn more about the four main types of evidence for evolution: the fossil record, comparative anatomy, comparative embryology, and molecular biochemical evidence.

Fossils are crucial evidence for evolution because they show how different species have changed over time. I find it useful to collect the evidence charts, even though they are unfinished, just in case the partner that takes it home is absent the next day. In fact, to the untrained eye, it would be virtually impossible to distinguish between them. For example, birds are all closely related species, however, many birds have differing features. As seen in the picture below, all have the pattern of one bone, two bones, lotsa blobs, and digits.
