Science Learning Community: Science and Engineering Lesson Plans Design Inspired By Nature Ellen Goodman, Marci Jahnke July 18, 2014 INFORMATION ABOUT THE LESSON Grade Level and Subject Area 9-12 Biology Time Frame Introduction: Biomimicry (10 min.) Part I: Reverse Engineering (45 min.) Part II: Product Design (45 min.) Part III: Product Presentation (60-75 min.) Objectives: Upon completion of this unit, students will be able to: • Explain how biomimicry can be used to enhance engineering design. • Describe the process to reverse engineer an object. • Explain how brainstorming in a team can lead to more creative ideas. Next Generation Science Standards HS-LS4-6 Create or revise a simulation to test a solution to mitigate adverse impacts of human activity on biodiversity. HS-ETS1-2 Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering. Standards for Technological Literacy STL8 Students will develop an understanding of the attributes of design STL9 Students will develop an understanding of engineering design STL11 Students will develop the abilities to apply the design process Common Core State Standards in Mathematics MP.2 Reason abstractly and quantitatively. Common Core State Standards in English and Language Arts SL.11-12.4 Present claims and findings, emphasizing salient points in a focused, coherent manner with relevant evidence, sound valid reasoning, and well-chosen details; use appropriate eye contact, adequate volume, and clear pronunciation Funded by an Elementary and Secondary Education Act Title IIb Wisconsin Improving Teacher Quality Grant in Partnership with the University of Wisconsin-Stout Page 1 Science Learning Community: Science and Engineering Lesson Plans Prior Learning Students will have learned that organisms have diverse adaptations for their survival in various situations. Students will also have observed in their daily life that some human-engineered products mimic adaptations organisms have. Errors or misconceptions students may have include that similar structures may be used for similar or different functions. Materials Each team needs: • • • • • • 1-2 flowers (lilies, sunflowers, or snapdragons) Tools to reverse engineer the flower (i.e., toothpicks, tweezers, cutting object) 1 magnifying glass 1 sheet of blank paper Markers or colored pencils 1 copy of the Exploring Biomimicry Worksheet LESSON IMPLEMENTATION Objective: Upon completion of this lesson, students will be able to: • Explain how biomimicry can be used to enhance engineering design. • Describe the process to reverse engineer an object. • Explain how brainstorming in a team can lead to more creative ideas. Pre-Assessment Students will use the Think-Pair-Share strategy to brainstorm what they think Biomimicry is and identify products that currently exist that were inspired by nature, discuss with a partner, then share with the class. Procedures Time Instructional Strategies/Learning Tasks Purpose 10 min. 1. Introduction – Discussion of Biomimicry (see website for content to discuss in Introduction/Motivation and Background sections) The Introduction will help students understand what Biomimicry is; 45 min. 45 min. 2. Part I – Reverse Engineering: Students will carefully take apart a flower and sketch its components. Complete the “Exploring Biomimicry worksheet.” The teacher will follow up this with a group discussion of students’ observations. 3. Part II – Product Design: Students will choose their own natural artifact (organism adaptation) and design a product inspired by that artifact. a. Have each group brainstorm a potential product for about 10 min. b. Require students to develop a design which helps solve an environmental, health, or medical problem Part I will help students see that all organisms have structures that can be used for other purposes and to model the reverse engineering process required for Part II; Part II will enable students to use the Engineering Design Process to build a new Funded by an Elementary and Secondary Education Act Title IIb Wisconsin Improving Teacher Quality Grant in Partnership with the University of Wisconsin-Stout Page 2 Science Learning Community: Science and Engineering Lesson Plans product; 60-75 min. 4. Part III – Product Presentation: Students will present their product to their peers (who will act as a patent review board) to obtain approval for their design. Part III will enable students to communicate their results in a real-world situation. Formative Assessment 1. Collect and Evaluate Think-Pair-Share. 2. Have students incorporate the “Exploring Biomimicry worksheet” into their Science Notebook. Collect and evaluate the notebook. 3. Utilize a rubric for scoring the presentation. Closure Students will present their product to their peers, who will act as a patent review board, to obtain approval for their design. Summative Assessment The teacher should incorporate questions related to the Engineering Design Process into his/her unit test. Reference Cooper, L., Zarske, M., & Yowell, J. (2009).
