Biology Curriculum Guide GPISD Theme Evidence of Evolution Number of Days 4 days Overview Student knows evolutionary theory is a scientific explanation for the unity and diversity of life. Prior Knowledge 6.12.B Misconceptions Key Vocabulary recognize that the presence of a nucleus determines whether a cell is prokaryotic or eukaryotic Difference in evolution and the theory of evolution Students mistakenly think that heterotrophs came from autotrophs. Students think that if it is on the Internet it is a valid source; information needs to come from a reputable science organization (i.e. Institute for Creation Research DOES NOT meet criteria for scientific explanation specified in the TEKS 7G statement) homology (homologous/homologies), biogeography, fossil record, molecular, developmental, anatomical, phylogenetic tree, cladogram, common ancestor Student Expectations (Science and ELPS) 7A TSW analyze and evaluate how evidence of common ancestry among groups is provided by the fossil record, biogeography, and homologies, including anatomical, molecular, and developmental 7B TSW analyze and evaluate scientific explanations concerning any data of sudden appearance, stasis, and sequential nature of groups in the fossil record 7G TSW analyze and evaluate scientific explanations concerning the complexity of the cell. Updated 12/12/2012 2012-13 Teaching Targets Students need to analyze all the different types of evidence presented in the 5E Lesson: Evidence of Evolution o Fossil record sedimentary rock layers - PH Biology textbook p. 382, 417-420 o Biogeography geographic isolation - natural or migration p. 383 o Homologies anatomical (i.e. similar bone structure) p.384 molecular (i.e. similar genetic strands) p. 454 developmental/embryological (i.e. chick embryo) p.385 o Students need to create and analyze phylogentic trees p. 453 Students need to be able to identify the common ancestors and the most/least related species on a phylogenetic tree. Students need to summarize the significance of all the different pieces of evidence supporting evolution including their geologic timeline, molecular homologies, and developmental homologies. Students need to research 7B using teacher-approved resources and a teacher-made rubric for their project, essay, or research paper. o Students need to complete a research essay that gives valid explanations concerning the controversies surrounding the data found in the fossil record; stasis = no change Students evaluate the following hypotheses: o Endosymbiotic hypothesis analyze and evaluate the hypothesis in reference to the 1 Biology Curriculum Guide GPISD o Origin of Life hypothesis/theory mitochondria TSW analyze and evaluate the evidence regarding formation of simple organic molecules and their organization into long complex molecules having information such as the DNA molecule for self-replicating life. 9D English Language Proficiency Standards (ELPS) use strategic learning techniques such as concept mapping, drawing, memorizing, comparing, contrasting, and reviewing to acquire basic and grade-level vocabulary; 1C Required Theme Activities 2012-13 Focus Points Students will create an Evolution Lapbook and add Evolution Lapbook application activities to target vocabulary of the unit on both natural selection and evidence of change. - NEW Focus Points Word Wall: Evidence of Evolution English Word Wall: Evidence of Evolution Spanish 5E Lesson: Evidence for Evolution (TEA) Top 10-12 key vocabulary terms to place on your classroom word wall for students to view and use. Students will focus on the different types of evidence presented in the 5E Lesson: Evidence of Evolution o Cell Phone Evolution (in 5E) o Engage o o Dating the Fossil Record Activity (in 5E) Fossil Record Notes Booklet o Fossil record o Biogeography USGS_Fossil Evidence_puzzle legend USGS_Fossil Evidence_puzzle pieces USGS_Fossil Evidence_worldtoday USGS_Fossil Evidence o Biogeography o Structural and developmental homologies embryo (developmental) bridge natural selection to evidence of change and fossil record sedimentary rock layers geographic isolation (natural or migration) similar bone structure (anatomical), chick o Structural and Embryological Homologies Notes Booklet o Molecular Evidence (in 5E) o Molecular homologies - similar genetic strands and amino acid sequences o Creating and Analyzing a Cladogram (in 5E) o Students will create and analyze a cladogram. Updated 12/12/2012 2 Biology Curriculum Guide GPISD Supporting Resources Reading to Learn Focus Points Life Before Oxygen Student reading passage to help address TEK 7G. NEW Graphing Lab - Molecular Evidence Activity 2012-13 NEW Creating Cladograms Students will (1)sequence information using items which overlap specific sets; (2) relate sequencing to the Law of Superposition; and (3) show how fossils can be used to give relative dates to rock layers. Molecular homologies - similar genetic strands and amino acid sequences Students will create and analyze phylogentic trees. Online Resources Fossil Evidence Students will examine five transitional species that fill so-called gaps in the fossil record. (7B) Understanding Evolution University of Berkeley website A Brief History of Life Students will watch an animation which describes the major events and species on the planet from the Precambrian Era to present The Emergence of Life on Earth by Iris Fry The Oparin-Haldane hypothesis is discussed as well as the Miller-Urey experiment Assessment Formative Assessment - Molecular Evidence of Evolution Updated 12/12/2012 Avoiding common pitfalls Focus Points Students analyze the amino acid sequences of various primates to determine relatedness. 3
