A) scientific method
any factor, trait, or condition that can exist in differing amounts or types
Variables
What is the 1st step of the scientific method?
Make an Observation
The information (evidence) gathered from observations and experimentation is called
Data
Horseplay is totally allowed during labs
FALSE
What does CER stand for?
Claim
Evidence
Reasoning
What is a hypothesis?
An educated guess or prediction of what you think the outcome will be
What 2 words should always be in your hypothesis statement?
If, Then
Scientists are the only individuals who use the scientific method True or False
False - WE ALL USE IT
How do you properly and safely smell chemicals/lab materials?
Wafting
unchanged, used as the comparison in an experiment - the "standard"
Control
statement that answers the question/ statement of your understanding of the results
Claim
Gathering information by using your senses
Observation
A graph that shows data over time
line graph
Before starting a lab you should:
a - just start messing with materials until it works
b- wait for instructions
c- read directions and listen to teacher instructions
d- get all your snacks ready to eat for the day
B and C
Data, details, and facts that support your claim
Evidence
graph for comparing data collected by counting
bar graph
the variable you manipulate, control, or vary in an experimental study to explore its effects
A. | Dependent |
B. | Independent |
C. | Control |
D. | Uncontrolled |
B- Independent
Making sense of the data, looking for patterns, finding trends, making a graph ect.

A) the types of plants
B) the amount of salt in the water
the amount of salt in the water
What are the steps to the scientific method?
Observation

Conclude
what changes as a result of the independent variable manipulation in experiments (what we measure)
dependent variable.
