Ch. 1 Sec 3+4 Flashcards
(40 cards)
In an emergency situation, how do you get the teacher’s attention?
Call out
In a normal situation, how do you get the teacher’s attention?
Raise your hand
How many people are allowed up from the table at a time
one
how many fire extinguishers are in the laboratory classroom
two
where do you put used chemicals at the end of an experiment?
chemical waste
where are the first aid kits located in our classroom?
on eyewash sink
When should you wear safety goggles (4 TIMES)?
When working with: •Flames •Glassware •Chemicals •Clean Up/Using Machinery/ Substance that can get in your eyes
Our class is usually divided into four segments.
When is each segment and what occurs in each segment?
ONE:
First few minutes= Bell/Read AR/ Lab preparations
TWO:
Second few minutes= Mrs. Nemitz makes announcements
THREE:
Third part= Working
FOUR:
Fourth part= Clean up
What should you do if you catch fire?
- Stop, drop, & roll.
- Fire Blanket
What’s technology?
MCMS
- Makes life easier
- Changes natural world
- Meets needs
- Solves problems
List the steps of the technology design process in order.
IRDBTC
1) Identify a need
2) Research a problem
3) Design a solution
4) Build a prototype
5) Troubleshooting and redesigning
6) Communicating the solution
Identifying the cause of any problems in a design is an example of
troubleshooting
An example of troubleshooting and redesigning used by early engineers when building the early computer mouse was
Steel ball changed to/was replaced with rubber because steel was noisy and dirt got in it.
After engineers identify the need they must
research the problem
A working model used to test a design is called a
Prototype
The first step in the technology design process is to
identify a need
After a design has been tested successfully, what should engineers to to share information about the product?
Communicate the solution
What stage of the technology design process involves coming up with ideas or different ways to solve a problem?
Design a solution
In designing a toy car, considering how big the final product will be is an example of a
constraint
Once the causes of a problem or trouble with a product are discovered the next step is to
redesign
What types of things are involved in the DESIGN A SOLUTION STAGE?
BCTR
- Brainstorming
- Constraints
- Trade offs
- Risks&Benifits
Inputs,processes, outputs, feedback, and a goal are all involved in
technological system
The result or product of a process is called an
output
In deciding whether to use a technology, people must analyze
risks and benefits
