True or False
Random
100
The procedure scientists use to help them explain why things happen is called...?
The Scientific Method
100
These are what you do NOT change in the experiment.
Constant (variables)
100
True or False? Always repeat your experiment.
True…to rule out any errors!
100
“The juice is sour” is qualitative or quantitative?
Qualitative (use your senses)
200
This is what you’re trying to find out. It’s always written in the form of a question.
The Problem
200
What is the difference between qualitative observations and quantitative observations?
Qualitative= qualities (use senses)
Quantitative= quantities (use #s)
200
True or False? Inferences can be “off the wall.” (crazy)
False…they must make sense based on your observations.
200
If you throw different airplanes with the same force but they travel different distances, what is the dependent variable?
The distance they travel (depends on what was changed on the plane)
300
What are the 2 different types of observations known as?
Qualitative and Quantitative
300
These are what you DO change in the experiment.
Independent variables
300
True or False? “The plant is long” would be considered a quantitative observation.
False…There are no numbers present. You can see it is long by using your sight.
300
If you’re looking at a picture of a child playing in sand, which would be the observation… the child is at the beach or the child is happy to be at the beach?
The child is at the beach is the observation.
400
This is a conclusion that is made after making observations.
Inference
400
Analyze data and summarize findings during this stage of the scientific method.
Conclusion
400
True or False? Variables in an experiment always change.
False…controlled (constants) always remain the same from trial to trial in an experiment.
400
What are examples of human errors in scientific experiments?
Miscounting or inaccurate measurements.
500
This is an educated prediction about what will happen in your experiment.
Hypothesis
500
These change in response to the independent variable.
Ex. If more water is added, the height of the plant will change.
Dependent Variable
500
True or False? There are 10 steps in the scientific method that we’re learning.
False
500
What conclusion can you make from the data shown?
Virginia has a higher population rate than Maryland or West Virginia for every year shown.
In 1974, Virginia and Maryland had a population rate over four million.
West Virginia's population decreased then increased.
