What is the first step of the engineering design process?
Identify needs
OR

What is technology?
Give an example.
Anything that helps us in our everyday life
In a system where solar cells are used to collect energy from the sun and change it into electricity for us to use in our houses, identify the input and output.
Input: Sun
Output: Electricity
Why do we build prototypes
So we can test and improve our design
What is a prototype?
A model of our design that we build and test
What is a tool?
A device that helps us do a job
Name a risk of having computer games as a form of technology
less exercise
What does feedback tell us about a system
Whether or not the system is successful
After we build and test a prototype, what do we do?
Evaluate the design. Look for ways to improve it.
What is engineering?
Using science and math to find solutions and create designs
Name some tools that would help us find out how quickly a model airplane can fly
measuring tape, meterstick
clock, timer
Is technology only electronics?
NO!
What is a designed system?
Tools, parts, and processes working together
