Introduction to Physical Science Flashcards
A way of learning about the world around us
Science
Using one or more of your senses to gather information
observing
making a forecast of what will happen
predicting
a possible explanation for a set of observations
hypothesis
a factor that can change an experiment
variable
a variable that is purposely changed to test a set of observations
control variable
help you stay safe when doing science activities in the lab
good preparation
how people change the world around them to solve practical problems
technology
a person who is trained to use both technological and scientific knowledge to solve problems
Engineer
a factor that limits or restrict a design
constraint
facts,figures, and other evidence gathered through observation
data
a well tested explanation for a wide range of observations
theory
a statement that describes what scientist expect to happen every time during certain conditions
law
the process in which members freely suggest any creative solutions that come to mind
brainstorm
the process of analyzing a design problem and finding a way to fix it
trouble shooting
involve numbers or measurement
Quantitative Observation
study of matter, energy and the changes they undergo
physical science
full size working model
prototype
has had a large impact on society
Throughout history technology
variable being changed
independent variable
the variable expected to be changed because it depends on the independent variable
dependent variable
hypothesis must be….
testable by observation or experiment
