Students will explore the need for renewable energy and identify wind as a source of renewable energy. As a class students, will 3D design and print a community that uses electricity generated from a 3D printed wind turbine to power the community’s lights.
The complete kit containing materials for this lesson plan can be purchased from Polar 3D or you can use your own classroom materials.

Single Lesson Plan
The Windy City
Step 1. Why Do Cities Need Energy?
Brainstorm: Why do cities need energy? Have students create a list of all the things that a city needs power for. Then ask your students, where does all that energy come from?
Paper, pencils, whiteboard
|Step 2. Read Energy Island By Allan Drummond||Read the book Energy Island by Allan Drummond. This story is about a real island in Denmark that switched almost completely to wind power! Follow the book with a discussion about what renewable energy is and why it is important to use renewable energy – have students brainstorm ideas and write them on the board.||Book: Energy Island by Allan Drummond White board|
|Step 3. Exploring Energy With Learning Stations||Explore how wind can make electricity. Set up 3 different stations for students to explore wind energy and electricity. Station 1: Hand held motor. Students spin the handle and the light blub lights up. Hook one motor up to the multimeter and have students read the voltage that comes out. What happens when they turn the crank slow or fast? What happens when they reverse the way they turn the crank? Station 2: Wind lift. The wind lift will need to be assembled by the teacher before class. Here is a video with instructions on how to construct the wind lift. Use a fan to make the wind mill turn and lift the bucket. Have some metal washers on hand to use as weight to lift. What is the most weight the wind mill can lift? How does the speed of the wind affect how much weight can be lifted? You will need a small fan for this station. You can also have cardboard, plastic, and scissors available at this station for students to create their own windlift blades. Do they think they can create better blades? Station 3: Wind turbine Before class teachers should 3D print and construct one wind turbine. At the station students will use a fan to spin the wind turbine and see if it can light up the light bulb. Try different speed settings on the fan, what changes do you see in the light? You will need a powerful fan for this station. Here you can also have paper available for students to draw what they think would be the best design for the wind turbine blade. This drawing can be used later if you decide to have students 3D design and print their own turbine blades to test.||1. Hand held motor (In Tinkering with Turbines box) 2.

|Step 4. Sketch Your City||As a class, design a city that will be powered by the wind. Have students brainstorm what buildings are found in a city? House, stores, fire department, library etc. Assign each student a building in the city and ask them to draw their building design on graph paper. Remind students that the building will have to accommodate the string of lights. They should consider where the light will go in their building and how the strand of lights will enter and exit the building.||Pencils, graph paper|
|Step 5. Design Your 3D City||Students will now render their 2D drawing into 3D. Students will use the Makers Empire 3D Blocker or Shaper module to design their buildings in 3D using the 2D drawing as a guide. Remind students to consider the size of their building and the size of the opening for the lights to enter and exit.||Makers Empire 3D|
|Step 6. 3D Print Your City||Have the students vote for the best design for each building type. This will cut down on printing time and allow students to recognize the strengths of their classmates. If you would like to have something to print out for each student, a good option is to have students 3D design the blades they think would be best for the wind turbine. These blades can be printed and then tested to see which is the best by using the multimeter to see which blades create the most energy.||3D printer|
|Step 7. Assemble The City And Light The Lights||Assemble the city and power the lights with wind! See the wind turbine assembly video for how to connect the lights to the turbine.||Place to construct the city, string of lights, alligator clips, wire cutters|
|Step 8. Reflection||Have students consider why wind energy is important? What made the best wind turbine blade? Also, ask students where in their state would be the best place for a wind turbine? Does their state use wind turbines? Where are they located and why?||Computer for research, pencils|
