We can’t solve problems by using the same kind of thinking we used when we created them.

-Albert Einstein

WHY IS STEM EDUCATION

IMPORTANT?

WHAT IS TECHNOLOGY?

Technology

1. What is the technology?

2. What does it do? What problem does it solve?

3. How else could you use it?

4. What material is it made of?

5. What other materials could it be made of?

TECHNOLOGY CAN BE………….

An Object

A Process: part of a system or steps (directions, recipe card)

A System: do something with it

TECHNOLOGY CAN BE……….

Any human made thing used to solve a problem or fulfill a desire

What do you think an engineer is or what is engineering?

What do you think of when you hear the word engineering?

WHAT IS ENGINEERING?

Engineering is not usually considered a science. Science is about discovering the natural. Engineering is creating the artificial.

Engineers apply the principles of science and mathematics to develop solutions to problems.

WHAT IS ENGINEERING?

Some examples:

Playground, building, fence, bike, helmet, cell phone, cooler, pop can, pop, water bottles, apples, sunglasses, football, chair, sandals, watch, clothes

MAKE A LIST OF ITEMS THAT HAVE BEEN ENGINEERED IN THIS PICTURE

The four main types of engineering are:ChemicalCivilElectricalMechanical

Other branches of engineering include aerospace, biomedical, environmental, and manufacturing.

THERE ARE MANY TYPES OF ENGINEERING

Chemical engineers discover and manufacture: Plastics Paints Fuels Fibers Medicines Fertilizers Paper

Chemical engineers also play an important role in protecting the environment by inventing cleaner technologies.

CHEMICAL ENGINEERS

Civil engineers oversee the construction of the buildings and other structures that make up our world:

HighwaysSkyscrapersRailwaysBridgesWater reservoirs

Civil engineers are known to say it’s architects who put designs on paper, but engineers who actually get things built.

CIVIL ENGINEERS

This is the largest field of engineering

Encompasses the macro (huge power grids that light up cities) as well as the micro (devices smaller than a millimeter that tell a car’s airbags when to inflate)

Electrical engineers develop components for The most fun things in our lives

MP3 players, digital cameras, or roller coasters

As well as the most essentialmedical tests or communications systems

ELECTRICAL ENGINEERS

Mechanical engineers work in nearly every area of technology

If an object or system has a moving part, it has benefited from the influence of a mechanical engineer. Mechanical engineers often have to work with all other

branches of engineering.

Mechanical Engineers might develop: A bike lock An aircraft carrier A child’s toy A hybrid car engine A wheelchair A sailboat

MECHANICAL ENGINEERS

Ask: What’s the problem? What have others done? What are the constraints?

Imagine: What could be some solutions? Brainstorm ideas.

Choose the best one.

Plan: Draw a diagram. Make a list of materials you’ll need.

Create: Follow your plan and create it. Test it out!

Improve: Make your design even better. Test it out!

THE ENGINEERING DESIGN PROCESS

The ChallengeConstruct a boat that:

A. Will floatB. Will hold a large

number of pennies—the more, the better

How do we know that air exists?Can you see it, hear it, touch it, taste it, and smell it?

SCIENCE AND LITERACY

The Challenge: Prove that air exists Directions:

Work with a team. Assign jobs: marshmallow filler, air pumper, counter Add 1 cup of mini marshmallows to your clean bottle. Observe and draw your bottle in the observe section on your

paper. Place fizz saver on the bottle. Carefully pump bottle full of air. (try 35 pumps) Record what you did in the “do” section on your paper. What happened as air fills the bottle? Record your

observations in the happen section of your paper. Draw bottle again. Release the pressure by unscrewing the cap, but don’t take your

eyes off the marshmallows. Discuss results.

CONDUCT AN EXPERIMENT

SCIENCE: READING NON FICTION TEXT

Chemist

Flavorist/Flavorologis

t

1. Remove the wrapper from the first candy bar. Save the wrapper.

2. With a partner, examine the candy bar using sensory details.

3. Create a list ofSmellsTextureTastesWhat substances might be in the candy

4. Repeat with the second candy bar.5. Compare your notes with the candy bar labels.

THINK LIKE A FLAVOROLOGIST

Reading Non-fiction text: Text Dependent Questions1. Read the article: Cool Jobs: People with a taste

for chemistry2. Reread the 5 th paragraph. What does Dana

Sanza spend time doing most of her day at work? Locate evidence from the text to support your answer.

3. What do food companies often ask flavorologists to do? Locate evidence from the text to support your answer.

4. Why would companies what flavor chemists to recreate a synthetic flavor when they could just use real natural flavors? Locate proof from the article to support your answer?
