ASSIGNMENT 

As we discuss the realizations, Engineers and Scientists may have not considered the impacts and  Downstream affects of critical decisions, consider the actions which have led to the extreme pollution across the world, answer the following questions.  

Post your answers in the comment section to below questions. 

In your observations of the videos identify obstacles which would hold back or hinder the collection process of the ocean clean up and the interceptors 

Take a stance on whether these types of collection devices are serving the symptom or the cause in the fight against pollution and environmental inequality for some across the world? 

Work Power & Gears

POE PRE-ASSESSMENT

Principles Of Engineering I

Introduction 

1) Create a folder in your Google Drive name it "Engineering"
2) Once you create your folder follow this link Brain Teaser and make a copy in your folder. 
3) Answer the following question at the bottom of the GD on the new document. 

Please complete this initial engineering pre assessment.  Follow this link, make a copy, and put it into you Principles of Engineering folder.

Please complete this online pre assessment.


DESIGN & PROBLEM SOLVING, DEVELOPING SOLUTIONS, ANALYZING RESULTS

Biomimicry

How Mother Nature Has Influenced

Engineering

ways engineers have been inspired by design..

The Innovators Using Nature's Design Principles to Create Green Tech

Examples of Biomimicry design 

                                            Using Mother Natures Genius in Architecture 

 

Biomemetric materials 

    

Key Questions to consider before you begin your design.

1. Do shapes influence design?

2. Do Animals/environment  influence engineering /design?  

3. Does animals adaptation influence design concepts?

4. Think about what type of things could improve peoples lives

Application steps.

1) Think about answers to the questions above on your own

2) Find animal influences or something specific in mother nature

that influences you to INVENT or INNOVATE the design of a product

          

     FTWE (feathers, teeth, wings, eyes) 

Design your product...Concept must come directly from the above...Color changing chameleon.  Octopus rope...Does not have to work but has to have the conception of how something specific can be applied for a new product.

Used clay, straws, glue guns...very simple stuff 3 class periods to design/build/present 

Standards to be addressed

PBGR 1: The Nature of Technology

Students will identify and demonstrate the interrelationships between technologies and other fields, working to become technologically literate and adaptable in all situations.

PBGR 2:Technology and Society

Students will develop an understanding of the role technology played in

society throughout history as well as the influence/effect technology currently

plays culturally, socially and environmentally and how technologies can continually

evolve to benefit society.

PR. 4 Engineering Class

 

       PRINCIPLES OF ENGINEERING I 

Good Afternoon.  Today 10-6-21 you will continue working on the crane problem.  You should have all completed the below for the crane problem to date:

1) Problem statement

2) Research ideas saved to google doc with problem statement

3) Sketch ideas created, discussed among team members

4) Best solution selected

5) Collect materials and begin redesign build

NOTES for class:

All materials needed will be on the front table next to my desk.  I think most groups have supplies to begin the project.  Remember the supplies follow the guidelines as attempt #1.

If you complete the crane and are ready to test, go to the cantilever page on the blog and complete "Crane strain #2"  

         

           BEFROE WEIGHT TEST IS PERFORMED 

YOU MUST WEIGH YOUR CRAINE

MAKE THE PREDICTION BEFORE YOU TEST IT

COLOR RED WHERE YOU EXPECT FAILURE

TAKE A PICTURE BEFORE YOU TEST

TAKE A VIDEO OR SEVERAL PICTURES AS YOU TEST
