DESCRIPTION
WHAT IS TECHNOLOGY? Technology
Citation preview
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?

What was one thing that surprised you about STEM? Or was a new idea relating to STEM?
How will you take what you’ve learned today and apply it to your classroom?
