Ch. 1 Sec 3+4 Flashcards
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
A person trained to use both technological and scientific knowledge to solve practical problems is called an
engineer
Today we can share information quickly around the world because of technology so we are living in the
information age
what are some of the effects that technology has on society
- made life easier
* can share information quickly around the world
true or false: student drawers and yellow cabinet are for lab papers and experiments
true
true or false:lab aprons are required to be worn at all times
false
True or false: minor accidents should not be reported
false
Hot objects can be handled with
care
The penalty for not knowing or not following the 25 safety rules is
writing them out
The most important part of your grade comes from
daily activities
In this class you will learn
science facts, how a scientist thinks, and how a scientist experiments
