Prototyping
Brainstorming
Social Media Marketing
Iterating
2
What is biomimicry?
The study of plant growth
The study of bicycles
A type of bird migration
Studying and imitating nature to solve human problems
3
Is this a first or third angle projection?
First angle
Third angle
4
What is the role of the dependent variable in an experiment?
It is the variable that the scientist predicts
It is observed and measured as it responds to changes in the experiment
It remains constant throughout the experiment
It is manipulated by the scientist
5
What does criteria mean?
The software used for design
The specific color scheme of the project
The team members involved
The requirements for the design
6
What is the main purpose of Wind Tunnels in engineering
To test the project's resistance against hurricanes and storms
To observe how air flows around objects
To simulate tornado conditions
To generate wind power for the project
7
What is the main purpose of a technical drawing?
Creating abstract artwork
Communicating design and engineering ideas through illustrations
Designing logos for companies
Practicing freehand sketching
8
What is the independent variable in a scientific experiment?
The variable that the scientist controls and manipulates
The variable that changes in response to the experiment
The variable that depends on other factors
The variable that remains constant throughout the experiment
9
What is the approximate r-value of this scatterplot?
0.5
0.8
-0.8
1
10
What is the primary purpose of Drag and Airfoils in engineering?
To control the temperature of the project
To drag the project to completion
To create resistance against the wind
To enhance the visual appeal of the project
11
What are constraints?
The project timeline
Creative ideas for the project
The final product
The limits on the project
12
What is the correlation of a graph?
The order in which data is collected
The number of variables in an experiment
The process of mixing different data sets
measure of the strength and direction of a relationship between 2 variables
13
What is the relationship between lift and camber?
They are unrelated concepts
Lift is the weight of the project and Camber is its shape
They both refer to the same aerodynamic phenomenon
Camber is the force pulling down, while Lift is the force pushing up
14
What is heat?
A measure of the object's color
The total energy of an object
The transfer of energy between objects due to a temperature difference
The weight of an object
15
How would you describe Turbulent Flow?
The temperature of a liquid
Predictable and calm flow, like a slow river
Chaotic and jumbled flow, like a waterfall
The color of a liquid
16
What does each point on a scatterplot represent?
The number of pages in a book
A data value from a pair of variables
The temperature of the room
A piece of candy
17
What is the approximate r-value?
12
-1
-0.3
0.5
18
What happens during thermal equilibrium?
Temperature constantly increases
There is no net flow of heat between objects
Heat is actively transferred between objects
Objects have different temperatures
