1. STEM Agenda Week 31 4/8 – 4/12

2. Agenda 4/8 Learning Target: Brainstorm and research wind turbine ideas. Agenda: Turn in Safety Pledge!!! Review Wind Turbines Project (DUE 4/19) Begin Design Process Steps Define the Problem Brainstorm Research Finish All Safety tests on YOUR OWN time

3. The Problem Design and build two different model wind turbines to find which can generate the most energy. You will prove the energy generated by lifting weights and measuring the energy output. Constraints: Plastic or Balsa Wood? Turbine blades can be no longer than the radius of the box fans. Why? Complete and ready to submit to Kidwind Project website on April 15 th (Monday)

4. Problem, Brainstorm, and Research Problem: Design and create two model wind turbines that can generate the most energy. What are some things to consider? Materials Angle of blade Number of blades Shape of blades Wind speed of box fans Gear ratio High or low torque generator Document problem, brainstorming, and research in engineering notebook

5. HOMEWORK 4/8 Get your safety pledge signed! Finish any/all safety tests online Either print out and turn in or email me a screen shot of the test showing your name and score.

6. Agenda 4/8 (Period 5) Target: Research wind turbine ideas and begin designing blades. Agenda: Design Process for Wind Turbines 1.Define the Problem 2.Brainstorm 3.Research 4.Develop Ideas 5.Get signed off! Begin designing wind turbines?

7. Agenda 4/9 Target: Research wind turbine ideas and begin designing blades. Agenda: Design Process for Wind Turbines 1.Define the Problem 2.Brainstorm 3.Research 4.Develop Ideas 5.Get signed off! Begin designing wind turbines? TURN IN SAFETY PLEDGE

8. Develop Ideas (How to Document) You need two documented in your engineering notebook that addresses things to be considered from brainstorming and research. Draw a picture of the two designs you will try Shape dimensions Describe the designs how many blades why you have chosen this design

9. Agenda 4/9 Learning Target: Design wind turbine model blades. Agenda: Begin creating wind turbine blades Test on various wind towers & nacelles Modify your design to make your blades more efficient TURN IN SAFETY PLEDGE

10. Build Your Turbine Models See all gear ratio and motor combinations for the nacelle All design process steps 1-4 in notebook Mrs. Davis will check and sign off all team members Select and outline rotor blades on chosen material (balsa or plastic)
