1. Biology B Standard 3 Week 1 Ms. Darlak

2. Warm-up 03/18 Make a list of possible evidence that would prove that evolution is taking place. In other words what would you look for to prove evolution took place or can take place.

3. Agenda 03/18 Introduction to 3B Theory of Evolution Origins: How Life Began

4. 3B THEORY OF EVOLUTION History of Life Evidence of Evolution Theory of Evolution Patterns of Evolution

5. Standard 3B: Theory of Evolution Explain how multiple lines of scientific evidence support biological evolution and the history of events on Earth. Proficiency LevelsDescription Exceeds25%  Students will be able to analyze cladograms to determine if homologous, analogous and vestigial structures are a result of divergent or convergent evolution and if this process was the result of punctuated equilibrium or gradualism.  Students will be able to use the half-life formula (Absolute Dating) to determine the age of rocks and/or fossils. Meets75%  Students will identify and describe the following pieces of evidence in support of the Theory of Evolution: fossils, natural selection, common descent, biogeography, comparative anatomy, embryology, and molecular similarities (DNA).  Students will be able to analyze a diagram using the law of superposition to determine the “relative age” of fossils and rock layers.  Students will be able to identify the adaptation that made each evolutionary leap possible: invertebrate to vertebrate, fish to amphibian, amphibian to reptile, dinosaur to birds, reptile to mammal, and primate to human. DevelopingRefer to the vocabulary and “I Can Statements”

6. Birth of the Earth & Life

9. Warm-up 03/19 What was the earth thought to be like in the beginning? What was the atmosphere like? How do we know how old the earth is?

10. Agenda 03/19 Origins: How Life Began Evolution of Life Overview Progression of Life Clips

11. Origins: How Life Began What where the major changes that lead to prokaryotes and then eukaryotes? Which energy source is more efficient, with oxygen or without oxygen? Why was/is Oxygen so important to life? What is Ozone and why is it important?

13. Agenda 03/20 – 03/21 State Testing in Lab If you finish Testing can start research on Evidence of Evolution Poster on p.6

14. Evolution Evidence Poster p.6 DUE Tuesday April 2 nd Minimum of four different pieces of evidence you think supports evolution. Each piece of evidence needs an example. Neat and easy to read. Should be larger than a regular sheet of paper. See examples.

15. Warm-up 03/21 Origins: How Life Began mentioned several different experimental finds that help to put together the story of how life became possible on earth. How many can you remember?

16. Origins: How Life Began Evidence Mentioned Discovery of extremophile bacteria living today Rock formations in Greenland 3.5 billion years old with carbon Amino acids can be constructed in “early-like” environment created in a lab with building elements and electrical current. Discovery of amino acids in meteorites. Experimental results show that the amino acids not only could have survived but also may have fused into peptides with impact. Discovery of life deep in Earth's crust and oceans. Bacteria living deep below Earth's surface can obtain energy from methane, ethane, and propane gases (anaerobic) Bacteria that emerged following the Great Bombardment likely developed the ability to photosynthesize. Stromatolites—both modern and fossil cyanobacteria- created an oxygen-rich environment in which complex life could form.
