TECHNOLOGYTECHNOLOGY

TECHNOLOGY IS THE USE OF SCIENCE TO SOLVE PROBLEMS OR MAKE PEOPLE’S LIVES EASIER.

ENGINEERINGENGINEERING

ENGINEERING IS THE DESIGNING AND DEVELOPING OF A NEW TECHNOLOGY.

AN ENGINEER IS SOMEONE WHO DOES THIS.

There are steps to the Engineering Design Process, just like there are steps to the scientific method.

Problem Problem IdentificationIdentification

THE FIRST STEP IS TO IDENTIFY A PROBLEM THAT TECHNOLOGY MIGHT HELP OR SOLVE.

SOLUTION SOLUTION DESIGNDESIGN

THE ENGINEER PROPOSES A DESIGN THAT COULD SOLVE THE PROBLEM.

THE DESIGN SHOULD1.MEET A HUMAN NEED2.USE SCIENTIFIC PRINCIPLES3.BE SUITABLE FOR USE BY MORE THAN ONE PERSON

SOLUTION DESIGNSOLUTION DESIGN

FIGURE OUT HOW THE TECHNOLOGY WILL WORK.

EXPLAIN THE TECHNOLOGY, USE DRAWINGS OR MODELS.

IDENTIFY MATERIALS, ESTIMATE COSTS AND DEVELOPMENT TIME.LIST POTENTIAL BENEFITS AND

RISKS

IMPLEMENTATION AND IMPLEMENTATION AND TESTINGTESTING

WHEN A DESIGN IS ACCEPTED A PROTOTYPE IS MADE. A PROTOTYPE IS A WORKING MODEL OF THE NEW TECHNOLOGY.

The prototype is tested to see how it performs in real world conditions.

EvaluationEvaluation

Does the design work?

How can its success be measured?

Does it solve the problem?

Have risks been minimized?

Can it be improved?

RISKS AND BENEFITSRISKS AND BENEFITS

BENEFITS ARE WAYS THE NEW TECHNOLOGY MEETS PEOPLE’S NEEDS.

RISKS ARE HOW THE NEW TECHNOLOGY MIGHT HARM PEOPLE.

WEIGHING THE HARM AGAINST THE BENEFITS IS CALLED THE RISK-BENEFIT ANALYSIS.

What is bioengineering????What is bioengineering????

Bioengineering is the development of new technology in the fields of biology and medicine.

ADAPTIVE BIOENGINEERINGADAPTIVE BIOENGINEERING

CHANGING OR ADAPTING A DEVICE TO BE USED BY A PERSON WITH A DISABILITY.

LIKE A VOICE-ACTIVATED COMPUTER

ASSISTIVE BIOENGINEERINGASSISTIVE BIOENGINEERING

DESIGNING TECHNOLOGY TO HELP OR ASSIST A PERSON WITH A DISABILITY IN THEIR DAILY LIFE.

LIKE A HEARING AID

BIOENGINEERING IN AGRICULTUREBIOENGINEERING IN AGRICULTURE

BIOENGINEERS ADD OR CHANGE GENES IN FOOD CROPS. THESE GENETICALLY MODIFIED CROPS MIGHT BE CHANGED TO NEED LESS WATER OR STAY FRESH LONGER.

An ExampleAn Example

Problem: Much of the world’s

people do not have access to clean water. People have to walk for miles every day to carry water home. Usually this is the job of the women.

Solution:The Hippo Roller
