What is the first step in the traditional engineering design process?
Define the problem
What are the two types of variables
What is independent and dependent
Define Criteria
What is required
a model of a product
prototype
Lab work can be started immediately as you walk through the door.
False, wait for teacher instructions
This type of engineering involves the design of launch facilities, transit systems, and bridges:
civil and construction engineering
How do we test a hypothesis?
With an experiment
dependent variable
The dependent variable is what is being measured in the experiment.
A testable prediction is a...
hypothesis
A student is adding small drops of acid to a solution. They are leaning in closely to count how many drops of acid they are adding. The acid splashes and gets in their eyes. What was wrong?
Not wearing goggles
This step in the design process allows you to see if this will work or not.
What is test the prototype?
This variable changes because the independent was manipulated...
the dependent
independent variable
This is the variable in the experiment the scientist changes.
a series of steps followed to solve problems
scientific method
What is the correct way to check the odor of a substance? Be prepared to demonstrate.
Wave/Waft the fumes toward your nose
Which part of the process is when you consider the constraints and limitations?
Identifying the problem (Step 1)
If...then...because. This is used during this step.
What is formulating a hypothesis?
Define constraint
a limitation or restriction
If a hypothesis is tested and succeeds over and over, it is now a...
