Hominids - bipedal, Lucy, Homo sapiens. Discover How.I then tell the students that today we will begin to explore the evidence we have for evolution, and play Stated Clearly's movie, What is the Evidence for Evolution. I stop the movie atwrite " comparative anatomy " on the board, redisplay the evolution of videogame consoles, and ask students to help me identify examples of comparative anatomy between the consoles.

I repeat this process at:. Without a heavy cognitive load, they are using images to find patterns in data CCC Patternsand are using models to represent and understand phenomena SP2. I tell students that they will be working with their elbow partner, and instruct students to the right to gather their computers. Students on the left will be the day's recorders, so they must gather the the Evidence Chart. I explain that as they move through the four "stories", they must discuss what the evidence they are being provided means.

The recorder will then write their agreed upon answer on the evidence chart. I tell the students that they will have the rest of the class period to begin their exploration, but that they will continue the work on the site the next day. Note to teachers: Although the students could complete the modules independently, I find that having one "device" student and one "recorder" tends to foster better discussions as they proceed through the activity.

This gives the students a better opportunity to collaborate with a peer to find the best explanation SP7and engage in scientific discussions SP8. 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.

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. 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. While the students are working, I am circulating the room, ensuring that the recorders are accurately recording the conversation.

I am also interviewing partnerships asking them to explain what they are recording, giving me an opportunity to see how well students can communicate their findings SP8.

In the first part of this video, you can see snippets of the conversation I have with the students. In the second part, I asked the students what they see as benefits and challenges of working with a partner on this type of activity, which prompted a later conversation about strategies to help each other stay on task. 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.

To close day 2 of this lesson, I distribute the assessmentand have students complete this individually. This is not a summative assessment since we will continue to focus on the fossil record. The results of this interim assessment let me know how much support the students might still need during the next lesson.

We'll Help Your Grades Soar. Radiometric dating: technique that uses the natural decay rate of unstable isotopes found in materials in order to calculate the age of the material.

Extinction Events. Grade Level: 6 — 8 grades Introduction In this lesson students make connections between fossils and modern day organisms. Scientists compare the anatomy, embryos, and DNA of living things to understand how they evolved. Show your work for partial credit. Tell students that the scientists in the book investigate things they cannot observe directly, so they rely on other kinds of evidence to make inferences. Comparative Anatomy Fossils provide evidence of evolution.

For this fossils worksheet, students review how fossils form, how fossil age is determined, and what fossils reveal to us. As you do so, answer the following questions on a separate piece of notebook paper in complete sentences. An evolutionary pathway is represented below. Early evolutionary scientists like Buffon and Lamarck used comparative anatomy to determine relationships between species.

This is a great resource for the paperless classroom and can be used as stations, class work, or in many other ways. Radioisotope dating indicates that the Earth is 4.

The foramen magnum the large opening where the spinal cord exits out of the cranium from the brain is located further forward on the underside of the cranium than in apes or any other primate except humans.

Watch this video on evolution and natural selection. I play the movie untiland tell the students that today we will be paying close attention to the fossil record as evidence for evolution. Rapid evolution in a world emptied of ecological incumbents is expected if interspecific interactions are assumed to affect speciation rates 4, 12, 37, but multiple factors might set the pattern and pace of evolution, including the extent and duration of ecological collapse.

He relied heavily on fossils, but they provide no direct evidence of ancestry and are only really helpful given some prior understanding of genetics, which was not yet an existing science. Piece of Evidence Explanation of that piece of evidence you may make a bulleted list and.

Even distantly related species, like humans and sponges, can trace their shared ancestry back to a common ancestor.Fossils provide a window into the past. The earliest life.
