What are the 6 steps of the scientific method?
Problem,
Research/observation,
Hypothesis,
Experiment ,
Results/Analysis,
Conclusion
How does a scientist classify things?
By grouping together items in a certain way.
Why do scientists use the International System of Units?
Allows them to compare data and communicate with each other about their results.
Why is weight NOT CONSTANT?
Your weight on the moon is different because of gravity. Because of gravity
What is the equation to solve for Density?
Mass/Volume
How are observations made?
You make observations by using your 5 senses.
What do scientists need to do in order to evaluate?
To compare observations and data to reach a conclusion.
Define Length? Mass? Matter?
Length is the distance from one point to another.
Mass is a measure of the amount of matter in an object.
Matter is the material that makes up all solids, liquids, and gases.
Define Volume?
Volume is the amount of space an object or substance takes up.
What is the density of a block of Aluminum that weighs 48g and has a volume of 6 cubic centimeters?
8 c/g
What are the 4 types of observations and how do they differ?
Qualitative, Quantitative, Subjective, Objective.
Qualitative deals with qualities characteristics,
Quantitative deals with amounts or numbers,
Subjective based on the public opinion
Objective, based on the facts
What is the basic SI unit for length? How do you abbreviate this measurement?
meter(m)
What is the equation used to solve for Volume?
Multiply LxWxH
What is the SI Unit used for Temperature?
Kelvin(K)
What is an inference?
A conclusion that is reached by evidence, reasoning and observations
What is the basic SI Unit for measuring mass? How do you abbreviate this measurement?
Kilogram(kg)
Solve the following problem for Volume: The rectangular solid below has a length of 3m, width of 4 m and height of 6 m. What is its volume?
72 cubic meters
What is the SI Unit for time?
Second(s)
What is a prediction? Can you give an example of a prediction?
A prediction is a claim based on what will happen in the future based on past experience.
One example is I predict it is going to rain tomorrow.
What is weight and what tool do you use to measure it?
Weight is the force of gravity acting on an object. You use a scale to measure weight.
Define Density?
Density is a measure of how much mass is contained in a given volume.
How many seconds are in a week?
604,800
