The measure of how much mass is in a given volume of something is _____?
Density
(how tightly packed the molecules are)
What is a focus question?
The question that a scientist wants to find an answer to. Must be specific and can be tested and measured.
Quantitative data is _____?

What is a hypothesis?
An educated guess as to what the answer to the focus question is
Qualitative data is _____?
Observations
(Could include the color of leaves, appearance of leaves drooping or not, etc.)
Which is more reliable: a small sample size or a large sample size?

What is Life Science?
The study of all living things (also called biology)
The amount of space an object takes up is called _____?
Volume
What is a controlled experiment?
An experiment in which scientists carefully control and change JUST ONE THING while keeping everything else the same.
What is the Independent Variable?
The variable that the scientist manipulates or changes.
What are these called, which scientists use to present what they have learned?
1. _____: What you know; answers the focus question
2. _____: How you know it; data collected
3. _____: Why it makes sense; how the evidence supports the claim
1. Claim
2. Evidence
3. Reasoning
The investigation and exploration of natural events and of the new information that results from those investigations is called _____?
Science
Anything that has mass and takes up space is called _____? (Can be solid, liquid, or gas)
Matter
What is the last step of the scientific method?
A summary of all of the information gained from testing the hypothesis. We must analyze all data from the experiment to form a conclusion.
What is the Dependent Variable?
What is measured, or expected to change due to the manipulated variable.
What makes something sink or float?
If something has less density than water it will float. If it has more density than water it will sink.
What is the Scientific Method?
A process used to answer a question or solve a problem
A kind of matter with the same properties is called _____?
Substance
What are the steps of the scientific method in order?
1. Develop a FOCUS QUESTION
2. Do background RESEARCH
3. form a HYPOTHESIS
4. Perform an EXPERIMENT
5. Make a CONCLUSION
What are controls/controlled variable?
Factors that are kept the same to keep the experiment fair.
What is the equation used to find density?
D = M/V
