If scientists replicate an experiment and do not get the same results...
they should just go with the first person's results.
the data collection is working correctly.
the data collection must not be accurate or precise.

5
A tool that can help you interpret data is a
hypothesis
graph
theory
variable
6
Why might a scientific idea change?
Scientific ideas never change
It might change from a theory to a law
New evidence leads to the modification of an idea
Other scientists change their opinion
7
The first step in a scientific investigation is to
organize your data
draw conclusions from data
define the problem for investigation
design the experiment
