Middle School STEM Science Lab/Activity Planner Name of Lab/Activity: Blood Typing Web Activity Grade: 7 California Science Standard(s): (please copy and paste standards taught during this lesson) 2b: Students know sexual reproduction produces offspring that inherit half their genes from each parent. 2d: Students know the two copies (or alleles) of the gene may or may not be identical, and one may be dominant in determining the phenotype while the other is recessive. Learning Objective/Goal: The student will be able to describe how an offspring can have a different phenotype than its parents. The student will be able to explain how alleles can be codominant. Language Objective/Goal: (based on California Common Core Standards) Integrate quantitative or technical information expressed in words in a text with a version of that information that is expressed visually. Write informative/explanatory texts, including the narration of historical events, scientific procedures/experiments, or technical processes. Materials & Resources: Laptop with internet access Student copies of readings and formative assessment Procedure: 1st Class Period Part 1: Introduction to “codominance” with Punnett Square Practice Teaching Notes: (include timing) 2 Teaching Periods 1st Class Period Part 1: Introduction to “codominance” with Punnett Square Practice (30 min) Anticipatory Set: Basic Punnett Square Practice. Tie in: Punnett Square, parents can have different phenotype than offspring (carrier situation) Main Point: Codominance -> both Active Partic: Practice Punnett Squares that illustrate codominance Tie In: Blood Types are an example of codominance Part 2: In class, Blood Typing tutorial 1 Project how to access tutorial Model, lead completing the tutorial Introduce homework reading. Part 2: In class, Blood Typing tutorial 1 (25 min) -either on latops or printed Part 3: Homework, Blood Typing tutorials 2 & 3 Provide students with labeling packet Part 3: Homework, Blood Typing tutorials 2 & 3 This project has been made possible in part by a grant from the Texas Instruments Community Fund, an advised fund of Silicon Valley Community Foundation. 1 If students do not have internet access at home, provide those students with a hard copy of the tutorials 2nd Class Period Part 4: In class, Blood Typing Web Activity (55 min) 2nd Class Period Part 4: In class, Blood Typing Web Activity Math Connection: Punnett Squares (Probabilty and ratios) Teaching Notes: Technology Extension of Learning: Web-based activity using individual computers/laptops with internet access Teaching Notes: Check ahead of time that the laptops can play the game.

Quiz: Write about their experience of being able to select the correct blood type to be transfused to a patient. Accurately identify which blood type to be transfused into patients with identified blood types. Teaching Notes: Strategies for EL and Special Needs Students: Vocabulary: Graphic organizers, homework – labeling, use of Codominance, blood type, antigens, images, modeling, and charts of compatible blood antibody types Alignment in science unit: (Brief description of lessons taught prior to & after this lab/activity) Unit: Genetics Prior knowledge/lessons: Punnett Squares, genotype, phenotype, dominant, recessive, alleles, traits, codominant textbook reading Post knowledge/lessons: What is and isn’t inheritable? – Crazy Adaptations Lab Brief description of lessons taught after this lab/activity: Crazy Adaptations: Lab in which students will identify possible genotypes and phenotypes of an imaginery creature, and identify if a trait is an inheritable adaptation.
