Mass describes the amount of matter in objects.
What is Mass?
100
D=m/v
What is the formula for density?
100
They are something that can change in a experiment
What are variables?
100
It is the application of science for practical purposes.
What is technology?
200
Select a need address.
What is the first step in the engineering process?
200
You can use spring scales or weights.
What can you use to measure mass?
200
m=v times D

What is a example of simple technology?
400
Test and evaluate.
What is the fifth step in the engineering design process?
400
The weight can change depending on where you are, unlike the mass, which is always the same.
How is mass different from weight?
400
It is a testable possible explanation.
What is a hypothesis?
400
It can only have one independent variable.
What is a controlled experiment?
400
It is the act of giving up a advantage for getting a better one.
What is a trade-off?
500
You are done!!
What is the last step in the engineering design process?
500
Yes, mass does have matter in it.
Does matter have mass in it?
500
Material to study that is trust worthy to use, and you can trust that it is not false.
What is trust worthy information?
500
Independent and dependent.
What are all of the variables?
500
It is a process of knowing what to do and to get a good object made.
