What system of measurement do we use in science class?
The Metric System

What is the first step of the scientific method?
Ask a question.
100
What is a conclusion?
An answer to your question, or what you have learned during the experiment.

What is the difference between a qualitative and quantitative observation?
A qualitative observation is a description that you make using ONLY your 5 sense, and a quantitative observation is a description that includes a number or an exact measurement.

Who was our Scientist of the Month for September?
Galileo.
200
What units do we measure mass in?
Grams
200
How many steps are there in the scientific method?
Six.
200
What is a quantitative observation?
A description that involves numbers of an exact measurement.
200
What is the difference between an observation and an inference?
An observation is a description that you make using your 5 senses and an inference is how you try to explain your observations.
200
What does our Measurement Oath state?
That we will promise to always write our numbers with decimal points in science class in preparation for the 8th grade state exam.
300
What is the tool that we use to measure volume?
A graduated cylinder.
300
What step is after Collect/Interpret Data?
Communicate.
300
What is an independent variable?
The variable/factor that the scientist changes to test the hypothesis.
300
What is the difference between mass and volume?
Mass is the amount of matter in an object and volume is the amount of space that an object takes up.
300
Time is always the ______________ variable.
The independent variable.
400
What are the 2 types of measurement systems?
The metric system and the conventional system.
400
What are the three steps that you must complete before you begin an experiment?
1) Ask a question. 2) Make a hypothesis. 3) Design an experiment.
400
What is a dependent variable?
The variable/factor that changes depending on the independent variable.
400
What axes do the independent and dependent variable go on in a line graph?
The independent variable goes on the x-axis and the dependent variable goes on the y-axis.
400
Name the steps for creating a line graph.
1) Make a title. 2) Label the axes. 3) Scale. 4) Plot your points. 5) Connect the points with a straight line.
500
How do we measure mass using a triple beam balance?
1) Place an object on the pan of the triple beam balance. 2) Move the riders- the large one first, the medium one second, and the small one last-- until the indicator is aligned with the Zero Mark. 3) Add the numbers of the large, medium and small rider together.
500
What is the third step of the scientific method?
Design an experiment.
500
Define inquiry.
Inquiry- the process of asking questions and finding answers to those questions.
500
What is the difference between a controlled variable and a constant?
Nothing! They are the same thing!
500
Why is it important that all scientists use the metric system?
So that the science can be translated throughout different countries.
