Tech Design Process 1-5
What is technology?
A way of changing the natural world to meet human needs or solve problems.
6. What is typically the first step in the technology design process?
Identifying the need/defining the problem.
11. After brainstorming, engineers may refine their ideas by making ______________or constructing _______________.
sketches, models
16. What do all systems have in common?
They are made of parts that work together.
21. True or false? Technology has been part of human history only in recent years.
False!
2. How are the goals of science and technology different?
Science studies the natural world to understand how it functions. Technology modifies the natural world to meet human needs/solve problems.
7. True or False? The best design is one that meets people's needs and has the fewest negative characteristics.
True!
12. What is a prototype?
A working model used to test a design.
17. Circle the letter of each part of a technological system.
a. inputs
c. processes
d. a goal
22. What did tools invented during the Stone Age enable people to do?
spears, axes, and spades enabled people to grow crops and hunt so they could stay in one place.
3. Someone who is trained to use technological and scientific knowledge to solve practical problems is called an:
engineer
8. Meaning of brainstorming:
a process in which group members freely suggest any creative solutions that come to mind
13. Is the following sentence true or false? A prototype can be a computer-generated virtual model.

18. What is the result or product of a technological system called?
output
23. True or false?
false
4. Circle the letter of each step in the technology design process.
a. researching the problem
b. building a prototype
d. communicating the solution
9. Define constraint
any factor that limits or restricts a design
14. Why might engineers redesign a product after working on the prototype?
To address (fix) any problems with the design.
