Experiment, Observation, hypothesis, Variables, Data
Parts that make up scientific investigations
100
Anything that takes up space
(sound doesnt, but air does)
What matter is
100
-L X W X H
- water displacement= water level rises- volume
How volume can be determined
100
Application of science for practical purposes
What is technology
200
1. define problem
2. Form hypothesis with a educated testable answer'
3. Investigate/Experiment
4. Identify Variable
5. Collect/Organize data
6. Analyze and draw conclusions
Scientific Methods
200
The amount of matter in a object. Objects of same sizes can have different masses
What mass is
200
the amount of mass in an object
WHat density is
200
Zippers vs. MP3
-microprossesors
yes, and no
If all tech is complicated
300
Field Investigations; life science
How scientific methods are used
300
Weight is the measurement of gravatational force, while mass is the amount of matter in something
How mass differs from weight
300
Consistes of mass unit divided by volume unit
Formula= mass divided by volume= density
How density is determined
300
thinking creatively, thinking methodically, using math and models, using a variety of tech, and science
The skills needed for engineering design
400
-well documented
- controlled variables
- repeated
- replicated by onthers
- peer review
- good evidence
Things that make up good scientific investigations
400
Weight= spring scale
Mass= triple beam scale
how mass and weight are measured.
400
1: Identify a need for tech w/ enough info
2: Brainstorm/research
3: Prototype made, tested, revised
How the engineering proccess works
500
trustworthy info; best science journals, academically good, etc.
how to evaluate the quality of scientific info.
500
Volume= amount of space taken up by an object
How the amount of space occupied by matter measured
