Jake is testing how light affects plant growth. He grows six plants in identical pots, with the same amount of water and fertilizer. Jake grows two of the plants without turning on any lights, two that get the lamp turned on for 6 hours a day, and two that get the lamp turned on for 12 hours a day. Which part of Jake's experiment is the control group?
He is growing plants in identical pots.
He is using the same amount of water
He is growing 2 plants in the dark
He is using the same amount of fertilizer
He turns the lamp on for 6 hours for two plants.
You are managing a large feed lot. A pharmaceutical company wants you to try a new antibiotic to treat shipping fever in newly arrived cattle. The company claims that it is more effective at a lower cost than your current antibiotic you are using. You will measure the temperature of the cattle to see whether or not it works. WHAT IS THE DEPENDENT VARIABLE (DV)?
Type of cow
Antibiotic
No Antibiotic
Temperature of Cattle
Mrs. Barton wanted to see how different types of music affected students' pulse rates. She played different types of music: heavy metal, rap, R&B, alternative, pop, country, and classical music. Identify the independent variable.
A game company gives a group of 20 students a brain-training app and says it improves memory. After two weeks of playing the game, all 20 students do well on a memory test. Why can't we trust the results of this test?
The scientist clearly changed more than 1 independent variable.
The scientist clearly changed more than 1 dependent variable.
The scientist doesn't have an experimental group to show improvement.
The scientist doesn't have a control group (students that didn't use the app) to compare with.
A Japanese company gives 50 people a new skin lotion to test in January. In April, they measured the dryness of their skin after using the lotion. The company then mae the claim: “Their skin looked better after 3 months because of the lotion!”
The scientist clearly changed more than 1 independent variable.
The scientist clearly changed more than 1 dependent variable.
The scientist doesn't have an experimental group to show improvement.
The scientist doesn't have a control group (people that didn't use the lotion) to compare with.
Casey tests whether studying in the morning is better than studying at night, as shown in the image. For his Unit 1 math test, he studies in the morning. He gets a B+. For his Unit 2 math test, he studies at night. He gets a C-. Casey concludes that studying in the morning is better. What is the MAIN problem with Casey's experiment?
Casey doesn't have a control group.
Casey changed too many dependent variables. You're only allowed to measure 1 thing.
Casey changed more than 1 independent variables: day/night, unit, phone, music, snacks.
Casey chose to do this for math, which is completely unpredictable. He should have done it for history class.
What is the independent variable?
Type of fertilizer
Average plant height
The effect of fertilizer on plant height
The effect of plant height on fertilizer
What is the BEST title for this graph?
The Relationship between Time Spent Studying and Test Grades
The effect of Time Spent Studying and Test Grades
Time Spent Studying

Jackie is testing how different types of paper affect how far a paper airplane can fly. The planes and distances are shown in the image. Jackie concludes that Cardstock Paper is better for paper airplane distance. What's the MAIN problem with Jackie's experiment?
Jackie has no control group, so any results don't have something to compare to.
Jackie has changed too many dependent variables and is measuring too many things.
Jackie has changed more than 1 independent variable (paper type and airplane style).
Jackie has no experimental group, and therefore isn't actually changing anything.
