lesson 1
the systematic study of natural events and conditions
what is science
a well supported explanation about the natural world
what is a scientific theory
an organized procedure to study something
experiment
a human heart is this kind of model
physical
the use of tools, machines, materials and processes to meet human needs
technology
observations, measurements, and other types of data scientists gather
what is empirical evidence
a representation of something in the natural world
a model
a testable idea or explanation
hypothesis
they are curious, creative and enjoy solving problems
a scientist
application of science and mathematics to solve real-life problems
engineering
true or false empirical evidence includes personal beliefs
false
a basic principle of nature that ALWAYS occurs
a law
a factor that can change in an experiment
variable
the three branches of science include, Earth and space, physical and ____________
life
first step in engineering process
identify a need
1 of 2 ways scientists are creative
come up with experiments or designing new experiments
an example of a model
maps, computer program, math equation or anything too big or small to study
the missing step:
define a problem, form a hypothesis, plan investigation, identify variables, interpret data, conclusion
collect data
data is collected and put into this
table
a test model of the product
protype
natural sciences include life, earth and _________
physical
an example of a good source
government or a college website
an investigation needs to be confirmed by
what is replication
the vertical axis is typically the value of this variable
dependent
the creative process in which many potential solutions are considered
brainstorming
