STEM AgendaWeek 314/8 – 4/12

Agenda 4/8Learning 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

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 15th (Monday)

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

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.

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
