What is a manipulated variable? What responds to it?
It is a parameter that is purposely changed. The responding variable is the variable that respond to it.
200
What is mass? What is weight?
Measure of amount of matter and object contains. Weight is the force of gravity on an object.
200
What is reproductibility and accuracy? Why are they important?
Accuracy refers to how close a measurement is to a true or actual value. Reproductibility refers to how close a group of measurements are to each other.
200
What is the line of best fit?
It is a smooth line that reflects the general pattern of a graph.
200
If you drilled a hole from one end of the earth to the other, about how long would it take you to reach the other side?
42 min and 12 sec
300
What is Scientific Theory and Scientific Laws?
A scientific theory is a well tested explanation for a wide range of observations or experimental results.
A scientific law i a statement that scientist expect to happen every time under a specific set of conditions.
300
What is the equation for volume and density?
Volume equals length times width time height. Density is mass over volume.
300
What do you need for the part two section of the quiz?
Knowledge, Graph paper, ruler and pencil.
300
What is a linear graph?
It is a line graph in which data points yield a straight line.

The mouth, saliva produces opiorphin, stronger than morphine.
400
What is it called when only one variable is changed at a time in a experiment.

400
What is the submerging method?
To measure an amount of water in a container, submerge a solid object, measure liquid, then subtract the liquid with the object with amount of original liquid.
400
What is volume?
Volume is the amount of space an object takes up.
400
What type of data doe a line graph display?
Line graphs are used to display data to show how one variable (responding variable) changes in response to another variable (manipulated variable).
400
Who was the president of the United States during the Civil War?
Abraham Lincoln.
500
Why must a hypothesis be testable?
It must be testable or your whole experiment would not be correct. The purpose of a hypothesis in an experiment is to be tested, so if it is not testable, then no information can be given.
500
What are the standard measurements for weight, mass, volume, density, time, and temperature?
Weight = Newtons or pound
Mass = Grams
Volume = Meter Squared
Density = Mass over volume
Time = Seconds
Temperature = Celsius or Kelvin
500
What are Qualitative and Quantitative observations?
Qualitative observations are descriptions that don't involve numbers. Quantitative observations are measurements which involve numbers.
500
What is data?
Facts, figures, and other evidence gathered through observation.
