What is Engineering?CONCEPTS

• Science is the study of the natural world, while technology is the study of how humans develop new products to meet needs and wants.

• Teams of people can accomplish more than one individual working alone.

Introduction to Engineering

• Scientists investigate

• Engineers create

• Technologies = products and processes created by an engineer and often used by a scientist

• Knowledge of science and math is necessary for the creation of new technologies


• Technological change is illustrated through inventions, innovations, and the evolution of technological artifacts, processes, and systems.

• Technology can have both positive and negative consequences – social, cultural, economical, political, and environmental consequences.


• Engineers, designers, and engineering technologists are needed in high demand for the development of future technology to meet societal needs and wants.

• An engineering notebook is used to record original ideas or designs.

• A portfolio is an organized collection of best works.

What is Engineering?Key Terms

• Agriculture

The raising of crops and animals for food, feed, fiber, fuel, or other useful products.

• Artifact

A human-made object.• Biotechnology

All technology connected with plant and animal life.


• CommunicationThe transmission of information through a common system of symbols, signs, behavior, speech, writing, or signals

• ConstructionThe act or process of building, erecting, or constructing buildings, roads, or other

structures• Energy

The ability to do work; one of the basic resources used by a technological system


• EngineeringUsing technological and scientific

knowledge to solve practical problems• Environment

The surroundings in which a person, animal, or plant lives

• ErgonomicsThe study of workplace equipment design

or how to arrange and design devices, machines, or workspace so that people and things interact safely and most efficiently


• IndustrialOf, relating to, or resulting from industry

• InventionA new product, system, or process that

has never existed before, created by study and experimentation

• InnovationAn improvement of an existing

technological product, system, or method of doing something


• Manufacturing

The process of making a raw material into a finished product; especially in large quantities

• Math

The science of patterns and order and the study of measurement, properties, and the relationships of quantities using numbers and symbols


• Nanotechnology

The science and technology of building devices, such as electronic circuits, from single atoms and molecules

• Process

Human activities used to create, invent, design, transform, produce, control, maintain, and use products or systems; a sequence of actions that combines resources to produce an output


• Science

The study of our natural world through observation, identification, description, experimental investigation, and theoretical explanations

• System

A group of interacting, interrelated, or interdependent elements/parts that function together as a whole to accomplish a goal


• Technology

The way people use resources to meet their wants and needs

• Transportation

The process by which passengers or goods are moved or delivered from one place to another

STEMWorking togetherto solve problemsbased on societalneeds and wants

How are each of them needed to

Create a Product?Example Science Technology Engineering Math

Pencil Discovery of graphite and the fact that rubber (an eraser) will remove graphite

Creating a writing device that doesn’t use ink

Designing a device with a graphite insert, an exterior holder, and an attached eraser

What is the optimal length, diameter, or shape for the device?

PHYSICAL NEEDS:

• Basic shelter

• Basic clothing

Engineering

Engineering uses scientific, technological, and mathematical knowledge to solve practical problems.

Engineers Do Many Things

• Invent – Develop a new product, system, or process that has never existed before

• Innovate – Improve an existing technological product, system, or method

Create

Build

Conceive

Design

Evaluate

AnalyzeOrchestrate

Invent

Improve

• An electrical engineer may design a GPS system for your vehicle.

• A pharmaceutical/chemical engineer may find a cure for disease.

• A computer engineer may build a computer the size of your watch.

• A mechanical engineer may create a robot to discover water on a planet.

• An agricultural engineer may evaluate the effects of global warming on food production.

Engineers Work to Solve Many Kinds of Problems

Engineers make our lives better

Discussion Questions

• What product or system would make your life better?

• Would this be considered an invention or an innovation?

• What types of engineers might work on this project?
