Branches of Science
The study of matter and energy.
Physical Science
Using one or more of your senses to gather information.
Observation
What branch of engineering designs solutions such as pollution control?
Environmental
Limitations put on the design of a solution.
Constraint
Thomas Edison invented the light bulb.
False - a team of scientists did and he was the one who marketed it
The study of bacteria, plants, animals and humans.
Life Science
The factor measured or observed in an experiment.
Dependent variable
An important part of engineering that helps engineers identify cause and effect relationships.
Patterns
The confidence that can be placed on the truth and accuracy of scientific fndings.
Credibility
The human stomach can dissolve razor blades.
True - experiments have shown that razor blades can dissolve in the stomach within two hours
The study of our galaxy and universe.
Astronomy
What will happen next in a sequence of events in an experiment is called making a ___________.
Prediction
These show engineers how chainging one part of a system might affect the other parts.
Models
A model that is used to test a design.
Prototype
Giraffes are 30 times more likely to get hit by lightning than people.
True -This is 30 times the equivalent fatality rate for humans.
The study of the weather, climate and air quality.
Meterology
What is the last step in the scientific process?
Communicate results.
A series of steps used to find solutions to specific problems
Engineering Design Process
A process of comparing the predicted benefits and costs of a solution.
cost-benefit analysis
Octopuses have tentacles.
False - They have eight limbs, but they're arms (for most species). Technically, when talking about cephalopods (octopuses, squids etc), scientists define tentacles as limbs with suckers at their end. Octopus arms have suckers down most of their length.
The study of the processes and properties of the ocean.
Oceanography
The factor that is changed by the scientist to observe how it affects the dependent variable.
Independent variable.
Before engineers work on a problem, they conduct_______ to see information on a similar problem.
Research
Requirements or specifications for a solution to be successful.
Criteria
You can actually die laughing.
True - And a number of people have, typically due to intense laughter causing a heart attack or suffocation. Comedy shows should come with a warning.
