Engineering Design Proccess
100
Experiment, Observation, hypothesis, Variables, data
Things that make up scientific investigatons
100
Anything that takes up space
What matter is
100
measurents. Water displacement= put object in water, and water level rises= volume! Formula: L x W x H.
how volume can be determined
100
Technology- the application of science for practical purposes.
What technology is
200
Define problem w/ an educated answer that must be testable. Identify variables. Organize /collect data.
Scientific methods
200
Amount of matter in an object.
What Mass is
200
the amount of mass in a object
What density is
200
Series of steps that lead to new production. Thinking creatively, thinking methodically, using math and models, using tech variety, science
What skills are needed for engineering design
300
Field investigations, Lab investigations, life science
how scientific methods r used
300
Weight is the measurement of gravitational force. Mass is amount of matter in an object
How mass differs from weight
300
Consists of mass units divided by volume unit.
How density is determined
300
Sometimes can be, sometimes cannot. Ex: Zipper vs MP3 player
If all tech is complicated
400
Well documented, controlled variables, repeated, repeated by others, peer review, and good eveidence
Characteristics of good scientific investigations
400
Weight= spring scale Mass= triple beam scale
how mass and weight are measured
400
1: Identify a need for this technology 2: Brainstorm/ research and have enough info 3: Prototype made, tested, revised limit options for changes
How the engineering process works
500
trustworthy info, best scientific journals, academically good .
The way to evaluate the quality of scientific info
500
volume.
How the amount of space occupied by matter is measured
