1 1 Lesson Plan Title: Wind Turbine Design Challenge Teacher Name: Hwa Tsu Subject: IB Physics SL Grade Level: 11 Problem statement, Standards, Data and Technology Asking questions and defining problems Establish driving question for the lesson plan or define problem students will be solving. Attach any documents used to establish the driving question or define the problem. School: North Central High School Can students design and build the most energy efficient wind turbine? (see project document at the end) Incorporating Next Generation Science Standards, Common Core, or State Standards State the standards that will be covered during this lesson plan. Include all standards which may apply (NGSS, Common Core, or State Standards). NGSS HS-PS3-1: Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are know. NGSS HS-PS3-3: Design, build, refine a device that works within given constraints to convert one form of energy into another form of energy.

2 Obtaining and evaluating information How will students be obtaining and/or collecting the information? STEM Energy Lesson Plan Elements Inclusion To accomplish this task, students will need to: Research and identify the factors which influence wind turbine efficiency. Build and test their wind turbine design. Use the wind generator equation to calculate the maximum theoretical power output for the turbine. Measure the actual power output for their turbine to calculate turbine efficiency. Post efficiency data on a Canvas discussion board and reflect on their design. Create a Sankey diagram to model possible energy losses in their system. 2 Analyzing and interpreting data How will students be analyzing and interpreting the collected data? Students will collect data on the following: wind speed, diameter of their turbine blades, and the measured power output of their wind turbine. Students will use this data to calculate the maximum theoretic power output using the wind generator equation (Power = ½ ρav 3 ). Students will calculate and post on Canvas their turbine efficiency using their actual power output and their theoretical maximum output. Using their turbine efficiency, students will create a Sankey diagram explaining possible sources of energy loss in their turbine. Use of technology and software Indicate the type of technology and software students will be using in order to implement this lesson plan. Prior to starting their wind turbine design and build, students will watch the following videos: Wind Turbine Introduction ( Wind Generator Equation ( Sankey Diagrams ( Students will use a digital anemometer to measure the wind speed at their turbine, a ruler to measure wind blade diameter, a multimeter to measure and calculate the power output (product of voltage and current) from the wind turbine. Students will post efficiency data and reflections on their design on a Canvas discussion board.

3 Collaboration, critical thinking and communication Collaboration Indicate how students will be collaborating during the implementation of the lesson plan Students will work in pairs to collaborate on a design for their wind turbines. Students will also collaborate in pairs for the construction, calculation, and analysis of their design and data. Students will collaborate with their colleagues by posting efficiency data and reflections on an online Canvas discussion board. 3 Critical Thinking How will the students evaluate the question or defined problem to reach an objective conclusion? How will the students being using the learned content and collected data to be able to critically think about the established question and/or problem on this lesson plan? Communication How will the students communicate their findings and conclusion regarding the established question and/or problem? References Students will research wind turbine designs. Students must construct their wind turbines to maximize output efficiency as determined by the maximum theoretical efficiency. Students will reflect on their designs and evaluate potential sources of energy loss from their designs. Efficiencies of the different turbine designs will be posted on a Canvas discussion board. Students will be asked to reflect on their turbine designs and provide feedback for their peers on the Canvas discussion board.

4 Teacher s References Include all references used to develop and implement this lesson plan. STEM Energy Lesson Plan Elements Inclusion Student s References Include all references students will need to complete this lesson plan. Students must cite any sources they used in their wind turbine design. Assessment Plan Assessment Plan How will the students be assessed during and/or at the end of the lesson plan? Include resources that will be used to assess the students for the lesson plan. Students must submit their final calculated efficiency for their design and a reflection on the design process. Specific reflection questions might include: What were the strength and weaknesses of their blade design? What specific improvements would the students do on their next blade and why do they choose those improvements? What would the students do differently if they could redo the activity? The students also need to show their Sankey diagram.

7 7 Wind Turbine Design Challenge One souce of renewable energy is to harness the kinetic energy of air particles in wind to spin a turbine and generate electricity. If you were to design a wind turbine, what factors do you need to take into consideration? Specifically with the design of the wind turbine, what factors might influence how efficient your wind turbine is? To help us better understand wind as an energy resource, your task is as follows: 1. You should research and identify the factors which influence wind turbine efficiency. 2. You must to build and test their wind turbine design. 3. You should to use the wind generator equation to calculate the maximum theoretical power output for the turbine. 4. You will experimentally measure the actual power output for their turbine to calculate turbine efficiency. 5. You will post efficiency data on a Canvas discussion board and reflect on their design. 6. You will create a Sankey diagram to model possible energy losses in their system.
