100
Anything that changes in an experiment.
What is a VARIABLE?
100
I grew two apple trees over the summer. One tree received fertilizer and the other one did not. The tree that was fertilized, grew more apples. The amount of fertilizer represents this kind of variable.
What is a the INDEPENDENT VARIABLE?
100
This last step in the scientific method answers the original question.
What is a CONCLUSION?
100
True or False: If your hypothesis was not supported, then the experiment was a failure.
What is FALSE?
100
The name of the tool used to measure the length of an object is called this.
What is a metric ruler or meterstick?
200
The variable that you change and make different in order to test it.
What is a INDEPENDENT VARIABLE?
200
The amount of money a child receives depends on how many lawns have been mowed during the summer. Name one of the constant variables for this scenario.
What is THE CHILD or THE LAWNMOWER?
200
An educated guess or prediction for what might happen in an experiment is called this.
What is a HYPOTHESIS?
200
Identify the mistake made: Gary decides he wants to test which boils faster regular Coke or Diet Coke. He takes two pots one made of aluminum, another made from cast iron. He measures out 50 mL of regular coke and 100 mL of diet coke. He places both on the stove and turns both to medium heat. He waits until the first one boils and turns off the stove.
What is TOO MANY VARIABLES? (Gary needs to keep the pots the same and keep the amount of liquid the same)
200
When you conduct an experiment a good practice is to repeat your experiment at least three different times in which you collect the data each time, and then average the data collected. What are these "three different times" called in the experiment?
What are TRIALS?
300
The variable that you observe or measure during an experiment.
What is a DEPENDENT VARIABLE?
300
The amount of homework a student has at night depends on how much he/she completed during study hall. This is the DEPENDENT variable in this scenario.
What is AMOUNT OF HOMEWORK HAS AT NIGHT?
300
The step in the scientific method process where you make graphs, look for patterns, and think about what happened.
What is the ANALYSIS?
300
An object masses 20.0 g using the metric balance. This is what type of observation?
What is a QUANTITATIVE OBSERVATION?
300
"The plant is pretty" is a valid observation. True or False?
What is FALSE. This is an opinion.
400
Something that stays the same to keep an experiment fair.
What is a CONSTANT (CONSTANT VARIABLE, CONTROL VARIABLE)?
400
A pendulum is swung with a short string and then swung with a long string. The number of swings back and forth is counted. This is the Independent Variable in this scenario.
What is LENGTH OF THE PENDULUM STRING.
400
Information, numbers, and observations you collect in an experiment is called this.
What is DATA?
400
The color of the liquid in an experiment changed from peachy yellow to lime green. What kind of observation is this?
What is a QUALITATIVE OBSERVATION?
400
If you’re looking at a picture of a child playing in sand, which would be the observation… the child is smiling or the child is at the beach?
What is "THE CHILD IS SMILING"? You don't know for sure that the child is at the beach.
500
The number of variables that you can change in a fair experiment.
What is one?
500
Bounty towels are found to absorb more water than Brawny paper towels. The "amount of water absorbed" is this kind of variable in this scenario.
What is the DEPENDENT VARIABLE.
500
The list of steps to perform the experiment is called this.
What is the PROCEDURE?
500
You see a boy sleeping in class while the teacher is reviewing a math problem on the board. The teacher ignores the sleeping boy. You think the boy must be sick or something. You think that the boy will soon go to the office and call home. What type of statement is "the boy must be sick or something?"
What is an INFERENCE?
500
"Where does the Universe end?" is a "good" scientific question for using the Scientific Method. True or False.
What is FALSE? This question is not testable.
