Operation Build a Bridge and Get Over It–7th Grade

Operation Build a Bridge and Get Over It

Hello Class!
We have received several images from around the world showing bridge failure. Check out the photos here:  CLICK HERE .  There’s one in Madagascar, an island nation off Africa, another in Suriname, a republic in South America, one in Mississippi after a hurricane, and a collapsed metal bridge in Nebraska. While each bridge collapsed (engineers say “failed”) for different reasons, the main cause always comes down to one thing. Share with your partners what you think may be the general cause for structural failure.  The main culprit is that the bridges are no longer able to support the weight placed on them.The city of Powder Springs requests that our team conduct a special mission to redesign and construct a bridge that will resist collapsing. We will use our understanding of the steps of the engineering design process to achieve the mission goals. The operation name is “Build a Bridge and Get over It.”

Your mission, which you must accept, is to design and construct a bridge for Powder Springs that will have a high strength-to-weight ratio. As always should any member of your IMF force be caught, the secretary will disavow any knowledge of your actions. This tape will self-destruct in five seconds. Good luck class.

Vocabulary/Definitions

compression: The squeezing or pushing (force) on a material, which tends to make it shorter.

dead load: The weight of a structure by itself when fully constructed.

ratio: A comparison of the size of one number to the size of another number.

shear: The sliding of material that causes layers to move in opposite directions.

tension: The stretching or pulling (force) on a material, which tends to make it longer.

truss: A structural frame based on the rigidity of the triangle shape and composed of straight members. Functions as a beam to support structures such as bridges and roofs.

STEM ACTIVITY

S/SCIENCE:  Research several engineers that construct bridges

T/Technology:  Design your bridge using “Bridge Building Design” program

E/Engineer:  Construct (build) your bridge using toothpicks

M/Math:  Calculate the strength-to-weight ratio of their final designs.

WHY ENGINEERING…….

Why Engineering in Middle School?

 

Engineering is a natural program for the integration of science, technology, engineering and mathematics, while sparking creativity among middle school students! In an ever growing and extremely competitive economy, the demand for well trained and knowledgeable engineers from many disciplines is at an all time high.  To meet these demands, it’s never to early to start thinking about a future in the fields of math and science.

 

 

The Pre-Engineering Technology class is designed to assist students in becoming responsible learners while they learn to work cooperatively with others. Modules are student directed, giving students control of their own learning experience. Through a combination of hands-on activities and multimedia curriculum, students explore the areas of math, science, technology, and language arts.  Every student’s unique learning style is accommodated and all students learn while having fun.

Food For Thought

Food for Thought……

  1. No matter what mistakes you make, they do not define you. Use what you learn from that and make a better choice the next time.
  2. Use your voice, even if you are soft-spoken or extremely loud. No matter how young you are, you have an opinion.  It does matter.
  3. Always offer compassion and friendship. It will cost you nothing, but you will gain everything.
  4. When you are old enough to vote…do so! If the polls are open, be there. You can’t make a change while sitting on your couch.
  5. Strive to be your own hero. Be someone you can be proud of 10 or even 20 years from now.
  6. Don’t ever be a puppet. You have the choice to be your own man or woman every day.  Make that choice.
  7. Find your passion. Use that to fuel the fire that is growing in each of you.
  8. Always forgive. It will give you freedom from resentment and bitterness.
  9. Embrace your weirdness. It is what makes you uniquely you.
  10. .Smile and extend a hand to those in need. You never know when you will be facing an obstacle that requires someone’s assistance.
