How are science and technology related?
They may lead to advances in each other.
What happens when the data in an investigation do not support the original hypothesis?
The hypothesis needs to be redone.
No
An experiment in which only one variable, the manipulated variable, is changed at a time is called a(n)

unit
How does Earth science overlap with life science?
Earth science studies systems that may include the living.
Why are scientific models important?
They help visualize things that are very small or large.
