Welcome to STEM Workshop

Welcome to STEM Workshop

• Day 2, Elementary Educators

2
Reflect Share

• What stood out in your mind from yesterdays
  workshop?

3
Goals

• Participate in design and redesign activities.
• Compare types of engineering design, redesign
  and reverse engineering.
• Reflect on current classroom activities and how
  they can be altered to elicit more opportunities
  for design and redesign.
• Familiarization with the Engineering Standards

The Wee Adams Family

• The Wee Adams family always seems to have a
  problem with the monsters of Monster Lake when
  they are trying to take gold from one side to the
  other. The monsters always steal some of their
  gold. The Wee Adams family is fed up and needs
  your help. Can you help the Wee Adams family get
  from one side of the lake to the other without
  having to walk in the water and risk losing their
  gold?

5
The Wee Brown Family

• The Wee Brown family just received word that a
  sick cousin must have an operation right away. He
  keeps getting bigger and bigger. The doctors say
  that he needs 12 bars of gold to cover the cost
  of the operation. The Wee Brown family will have
  to send the gold from their safe, but it will
  take hours or maybe days for them to unload 12
  bars from their safe. They may also have to take
  breaks to regain strength while unloading. Can
  you help them find an easier and faster way to
  put their gold into the car and drive to the
  hospital before their poor cousin explodes.

Engineering Activities

• Design
• Redesign
• Reverse Engineering

8
Design

• a type of engineering in which something is
  created to solve a problem or meet the needs of
  an individual or group. For example, the Wee
  Family activities were an example of designwe
  created simple machines from scratch to solve a
  problem for this group of people.

9
Redesign

• an existing product is taken and is altered so
  that it performs better.

10
Reverse Engineering

• an existing product is taken apart to determine
  how it works.

11
Brainstorm
12
What would your students say?

• How do humans use the wind?

13
Wind Energy

• Wind energy is the use of the wind as an energy
  source. A wind energy system transforms the
  kinetic (moving) energy of the wind into
  mechanical or electrical energy that can be
  harnessed for practical use.

14
Mechanical Energy

• Wind energy can be harnessed by sails for
  transportation (sailboats) and other purposes
  such as grinding grain and pumping water.

15
Electrical Energy

• Harnessing the wind for electricity generation is
  the most widespread use of wind energy today.
  Wind turbines, activated by the wind, generate
  electricity for homes, businesses, and for sale
  to utilities.

16
Wind Turbine Redesign

• The Whirly-Wind Company is evaluating their
  current wind turbine design, they are looking for
  designs that will generate more energy than their
  current model.
• In looking at their design, what might you alter
  to make the turbine more efficient?

17
Your Task

• The Whirly-Wind company has asked teams of
  engineers to use what they know about the current
  design to create a new turbine. As you work they
  ask each engineer to do the following
• Keep detailed notes about each design.
• Record the energy output for each design.
• Be ready by given time to unveil your final
  product.
• You may use any of the materials given to you for
  your design.

18
Presentation of Turbines

• Have a team representative bring the turbine to
  the front of the room.
• When your team is asked send the demonstration
  team up to hook your turbine to the multimeter.
• Good luck!

19
Closure Personal Journal

• Please take time to reflect on how ideas you have
  to implement elements of engineering and the
  standards into your classroom and teaching this
  school year.
