predicting
a possible explanation for a set of observations
hypothesis

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

theory
