100
The reason why you perform an experiment.
What is the purpose?
100
This is collected during an experiment.
What is data?
100
A summary of results from an experiment.
What is a conclusion?
100
The uncertainty for the following values: 13s, 14s, 15s
What is 1s?

The purpose of the following experiment: “A student wants to perform an experiment to determine if larger magnets are stronger than smaller magnets. To measure the strength of each magnet, he holds the magnet and determines how many small paper clips he can hang from it before the last one falls off. He repeats his measurement four times for each magnet and records his data.”
What is to determine if larger magnets are stronger than smaller magnets?
200
A prediction of what will happen that includes an explanation; not just a guess.
What is a hypothesis?
200
You organize data using this table.
What is a data table?
200
The data collected during an experiment is used as this during a conclusion.
What is evidence?
200
The best value for the following set of values: 20 min, 21 min
What is 20.5 min?
200
The independent variable in the following experiment: “A student wants to perform an experiment to determine if larger magnets are stronger than smaller magnets. To measure the strength of each magnet, he holds the magnet and determines how many small paper clips he can hang from it before the last one falls off. He repeats his measurement four times for each magnet and records his data.”
What is size of the magnet.
300
The variable that is deliberately changed.
What is an independent variable?
300
This is used to support a claim.
What is evidence?
300
What an experiment must be for a conclusion to be valid.
What is a fair test?
300
The uncertainty for the following set of values: 9 paper clips, 7 paper clips, 6 paper clips, 10 paper clips
What is 2 paper clips?
300
The dependent variable in the following experiment: “A student wants to perform an experiment to determine if larger magnets are stronger than smaller magnets. To measure the strength of each magnet, he holds the magnet and determines how many small paper clips he can hang from it before the last one falls off. He repeats his measurement four times for each magnet and records his data.”
What is strength off magnet? (number of paper clips)
400
The variable that is measured.
What is a dependent variable?
400
The average of the measurements you made. (add all the values from each trial and divided by the number of trials)
What is best value?
400
A good conclusion includes this much data.
What is all?
400
The best value for the following set of data: 16.1s, 17.2s, 16.5s, 17.0s
What is 16.7s?

Carlos wrote the following conclusion and reason about the results from an experiment in which three magnets (small, medium, and large) were used to pull paper clip. This experiment was a fair test: The following conclusion ______ (is/is not) valid: Conclusion: We conclude that there is no relationship between magnet size and strength. Reason: Our medium-sized magnet and our largest magnet both pulled the paper clip from the same distance away.
What is "is not?"
500
The format (way) that scientist report their ideas, procedures, results, and conclusion.
What is a lab report?
500
The range of a set of measurements. (the largest value minus the smallest value divided by two)
What is uncertainty?
500
The very last component of a lab report.
What is a conclusion?
500
The best value for the following set of values: 27mm, 29mm, 25 mm
What is 27mm?
500
What you show between an independent and dependent variable in a conclusion.
What is relationship?
