2. Introduction Let me introduce myself. Where I grew up
Where I went to school
Where I work now
What my company does
Why I became an engineer/technician
What I love about my job
Today I would like to talk to you about engineering

3. Today we will learn about engineering
Is anyone in the room an engineer?
Does anyone in the room have the skills and talents to be an engineer?
Lets find out! Raise your hand if you…
Is anyone in the room an engineer? No
Does anyone in the room have the skills and talents to be an engineer? No
How do you know? Rattle off a few fun questions and ask for a show of hands for those that do the things mentioned.
You may already be an engineer and not know it
If you sort your Skittles or M & M’s by color before you eat them, you just might be an engineer or have engineering talents You have a habit of destroying things in order to see how they work.
At Christmas, it goes without saying that you will be the one to find the burnt-out bulb in the string.
You have ever saved the power cord from a broken appliance. You have ever taken the back off your TV just to see what's inside.
You rearrange the dishwasher to maximize the packing factor.
If you have ever ripped open your family’s old television (or car, engine, microwave, or doorbell) just to see how it works.
If you look at a computer, a cell phone, a skyscraper, and think: “Why was it made this way? or How could it be made better?”
If you like to figure things out—a computer game, a brain teaser, the universal remote control.
 If you think about inventing things like a better toothbrush, a robot that cleans your room, a bicycle built for three.
If you love to get your hands on a good problem—the tricky, impossible-seeming kind.

7. Decide how many cups you need for your customers
Like an INDUSTRIAL ENGINEER!
Industrial engineering is a branch of engineering concerned with the development, improvement, implementation and evaluation of integrated systems of people, money, knowledge, information, equipment, energy, material and process. It also deals with designing new prototypes to help save money and make the prototype better. Industrial engineering draws upon the principles and methods of engineering analysis and synthesis, as well as mathematical, physical and social sciences together with the principles and methods of engineering analysis and design to specify, predict and evaluate the results to be obtained from such systems. In lean manufacturing systems, Industrial engineers work to eliminate wastes of time, money, materials, energy, and other resources.

Must be at least 10 inch high
Must stand for at least 30 seconds
Materials
Spaghetti noodles
Mini-Marshmallows
Big-Marshmallows
Ruler
Paper for drafting plan
Newspaper (for desk coverage)

17. Building Marshmallow Towers: Round 1

Do you think that if you had another try at this you could use your learnings and make a better tower?

20. Design Considerations
Tallest tower
Strongest tower
Strongest and Tallest

21. Lets take a few minutes and try to get some ideas from other structures…. Can they improve our Marshmallow Towers?

22. Great Pyramid of Giza Built 2560 BC
Tallest man-made structure for over 3,800 years
Oldest structure in the world? Maltese Temples 3600 BC. Not quite as tall.
The Great Pyramid of Giza (also called the Pyramid of Khufu and the Pyramid of Cheops) is the oldest and largest of the three pyramids in the Giza Necropolis bordering what is now El Giza, Egypt, and in a historical irony is the oldest of the Seven Wonders of the Ancient World and the only one that survives substantially intact. It is believed the pyramid was built as a tomb for fourth dynasty Egyptian Pharaoh Khufu (Cheops in Greek) and constructed over a 20 year period concluding around 2551 BC. The Great Pyramid was the tallest man-made structure in the world for over 3,800 years. Originally the Great Pyramid was covered by casing stones that formed a smooth outer surface, but what is seen today is mainly only the underlying core structure, with a few of the original casing stones that once covered the structure simply representing the four compass points around the base. There have been varying scientific and alternative theories regarding the Great Pyramid's construction techniques. Most accepted construction theories are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place.
There are three known chambers inside the Great Pyramid. The lowest chamber is cut into the bedrock upon which the pyramid was built and was unfinished. The so-called[1] Queen's Chamber and King's Chamber are higher up within the pyramid structure. The Great Pyramid of Giza is the main part of a complex setting of buildings that included two mortuary temples in honor of Khufu (one close to the pyramid and one near the Nile), three smaller pyramids for Khufu's wives, an even smaller "satellite" pyramid, a raised causeway connecting the two temples, and small mastaba tombs surrounding the pyramid for nobles.

How high did building your marshmallow tower go? Measure it with your ruler to find out high you built or put your structure to the test by putting the pre-selected mass test units on top of it to see if it will support them.
What shapes did you make with your marsh-mallows and spaghetti to create a sturdy tower?
What could you do to build a higher/stronger marshmallow tower? What would happen if you used different sized marshmallows? How about if you built a wider base or narrower base?
Be sure to predict what you think is going to happen. Then test your question.
Are marshmallows good building materials?
What other materials can you use to build a tower?
Try building a tower using clay and straws or toothpicks and peas.
