Mass, Weight or Both
It is measuring the amount of matter in an object
mass
measurements that change based on how much is in the sample you are testing
extensive
Describe the matter in a subject with LOW DENSITY
The matter is spread out far apart
What is the first step AFTER observing a natural phenomena?
Ask a question
Mark wants to know if a new fertilizer will make his plant grow faster. He buys a pea plant and a green bean and gives one the fertilizer and the other no fertilizer. He measures them on day 1 and day 20 then analyzes the data. What did he do wrong?
He used 2 plants, too many variables were changed.
It will not change, even if it is on a different planet
mass
measurements that will not change despite the sample size that is being tested
intensive
Describe the matter in an object with HIGH DENSITY
What is the FINAL step in the scientific method
Conclusion (analyze the data to determine what science is now learned/proven)
Why is the color of silver INTENSIVE
It will not change regardless of the sample size
It is a measurement of how much gravity is acting on an object
weight
Density of a material
Intensive (no matter how large or small the sample size, density will ALWAYS be the same for each specific material- ie. water is always 1g/mL)
When volume DECREASES but mass STAYS THE SAME what will happen to density
It will increase - the matter is getting closer together
Which step of the procedure is completing the test and finding results
What is mass per unit volume called?
Density
If you place an object on a planet with less gravity, this will decrease
weight
Mass of a material
Extensive- more volume will mean a higher mass measurement
volume also depends on the sample size- a bigger sample size will have a greater volume.
When volume STAYS the same, but mass INCREASES what will happen to density
Density will increase because there is more matter being squeezed into the same space, so it gets tighter
What should be done BEFORE writing a hypothesis
Research- a hypothesis should be an educated guess, so research is needed to make it educated
Which of these can never change for an object-
mass, volume, weight, density
density- all substances have a specific density
If you measure more volume, this will increase
both
Intensive- an object is either magnetic or it isn't. It does not matter how much of the subject is being tested.
Mass= 5 g
prism has the sides 4mL x 5mL x 3mL
what is the density?
.083 g/mL
Which variable is changed by the scientist?
Independent variable
Dependent variable is what you measure or the RESULTS
The gravitational strength at the poles is greater than the gravitational strength at the equator. What will happen to an object when it moves from the poles to the equator?
The WEIGHT will get lighter even though the mass stays the same
