changing technology?? •Society benefits when engineers

apply scientific discoveries to better the designs that are created.

How many of you want to engineers or designers, or teachers??

Write down what you want to be!!

Sum It Up!!• Is this process infinite or finite?• Ask: question..• Imagine: come up with solutions• Plan: create model• Critique: what’s good / bad• Improve: how can I make it better?

Let Do Another Example Together

• Ask: HOW TO GET BEST LOUD, clear, wireless, headphones

• Imagine: -jess phones, wireless phones

• Plan: Make my model• Critique: test them • Improve: fix the problems

Which Step??… A farmer came up with a new invention, a machine that could

identify the different types of corn. After building and trying to sell his invention, the farmer found that very few people want to buy his

machine. What step of the design process did the farmer NOT follow?

Which Step??Roger and James were

creating a new device. After spending countless hours

researching and brainstorming, they came up with their best solution. What should Roger and James do

next?

George Lucas had a “Eureka!” moment. He had a brilliant idea to design and make light

sabers like in Star Wars. What should George do

after building his prototype light saber?

Mini Project.. •You are going to Create your Own

Today’s Objectives•SWBAT identify and apply the

tools needed to test the design features of a prototype.

Objective:•SPI0807.T/E.1: Identify the tools and procedures needed to test the design features of a prototype.

Don’t Forget about our Competition

• What were some of the inventions??

The Engineering Design Process

•The engineering design process involves an ongoing series of events that incorporate:• Design constraints• Model building- build a prototype• Test• Evaluate• Modify and Re-Test

Steps of the Engineering Process

Procedures for Planning Your Prototype

•Always research and brainstorm before you design your prototype. Take into consideration things that you have seen work in the past for similar prototypes.

•Think about possible design constraints• Money• Time• Space• Availability of parts

Procedures for Evaluating Your Prototype

•Make sure you thoroughly examine your prototype after you test it to ensure that it meets your criteria and expectations• Does the design work as planned?• Does the design effectively solve the

original problem?• How can the design be improved?

Tools to Test for Strength• Spring scale-

measures force• Ex: weight is a

measurement of the force of gravity

• Weights of varying masses

• Pressure/force

Tools to Test for Length•Ruler•Meter stick•Tape measure

Tool to Test for Time•Stopwatch

Tools to Test for Volume•Graduated cylinder•Beaker

Tools to Test a Prototype for Hardness

•Hammer

Paper Airplane Design Lab• In groups of two,

we will complete the paper airplane engineering design lab.

Chickasaw Challenge• Complete the half slip of paper for

the Chickasaw Challenge..

• Remember that classes who are quiet and working get the group points..

Rapid Review.. Mini quiz• Telephone..

• What are the 5 steps for this invention using the engineering design process

A closer Look at the Design Process.. What does it mean to be an

engineer?

Lab: Part 1•10 Minutes..

•Create two designs that you want to fly

•Complete Procedure questions: 1, 2, & 3

Test Your Plane.. • 1 Person Flies at a time.. • You are not allowed to step across

that line when you are finished…• You need to measure the distance.• Complete data chart

What are the Behavior Expectations when

outside?

Question• Answer questions: what do you

need to improve on your design?? Why did you choose to change this.

• Improve Plane Design!! (7 minutes)

• I need a paper from EVERYONE for lab credit..

Exit Ticket• Pretend that you are creating a

jumpsuit that is designed to keep people warn in cold weather.. • Tell me what you would do at each

step of the 5 design process. • Example: Ask:

Chickasaw Challenge: Thurs.

• 1. What is the first thing that should be done when you are trying to engineer a product?

• 2. What should I do to my prototype after I create it?

• 3. Does the engineering design process ever end? Why or why not?

Today’s Objectives•SWBAT recognize and differentiate

between assistive and adaptive bioengineered products.

•SWBAT identify and describe intended benefits of technology.

•SWBAT identify and describe unintended consequences of technology.

Technology•Technology refers to the product or

processes that are designed to serve our needs

•There are two major types:AssistiveAdaptive

Bioengineered Products•Bioengineered products are

created from the use of technology (they are not natural but rather man made) to alter or improve living things

Assistive Bioengineered Products

•Assistive– technology that helps!!! Helps living organisms but does not change them permanently

•These products assist people, but they are not permanent

•Assistive products are created specifically for disabled people

•Examples: wheelchair, hearing aid, eyeglasses, prosthetic limbs, and antibiotics

Adaptive Bioengineered Products

• Adaptive– things that are adapted or changed to help people but are permanent

• Adaptive- you change something that already exists and make it more accessible to those with disabilities

• Examples: cochlear implant, artificial organs, biofuels

REMEMBER!!!!!!!!Biofuels•Biofuels are adaptive bioengineered products• These are fuels made from living things• They can be made from sugar cane, corn

(ethanol), olives (olive oil)• They are often burned in cars or factories

as a way to reduce dependence on fossil fuels

• Biofuels increase food prices because farmland that used to be used to harvest foods is now used for biofeuls

Think, Pair, Share• What do you think is the major

difference between the two.. • I can think of two : )…. See if you can

beat me!

Stand up..• Take a step forward if it is assistive. • Take a step backward if it is

adaptive

Study Guide for the whole unit..

• Take 10 minutes and complete the study guide as a group..

• When you finished I am going to call on a group to answer a question.. If you get it right you try to shoot a basket for a point..

• Team with the most points win..

Intended Benefit of Technology

•Intended benefits of technology are the desired outcomes of products

•Examples: cell phones help us communicate, the internet allows us access to information faster and more effectively, wheel chairs allow disable to maneuver easier

Unintended Consequences of Technology

•Unintended consequences of technology are uses or results that engineers do not purposefully intend in the design of their products

•These are usually negative

•Examples: wireless internet increases our cable bill, a surgery utensil gives you a scar, the production of biofuels increase the cost of corn to be used for eating

Intended or Unintended?•Cell phone towers detract from the

beauty of the landscape

Intended or Unintended?•Pollution from automobiles

Intended or Unintended?•Cell phones allow us to

communicate quicker and easier

•What are some the intended benefits of biofuels?

•What are some unintended consequences of biofuels?

•What are some the intended benefits of computers?

•What are some unintended consequences of computers?
