Scientific law vs theory
100
This part of the scientific method tests the scientific question to confirm or disprove your hypothesis.
Conduct an experiment
100
You and your friend would like to know if lemon juice will prevent apples from turning brown. You both cut apples into equal slices. Half of the slices are sprayed with lemon juice. All slices are stored in a sealed plastic bag. After 4 days, they are observed to see how brown they turned. What is the problem in this experiment?
You and your friend want to see if lemon juice will prevent apples from turning brown.
100
What is the independent variable in this experiment?
The special food
100
The one thing that scientist change in an experiment
Independent variable
100
True or false: Your hypothesis always has to be right for your experiment to be scientific.
False
100
True or false: Sharing your results will not lead to the formation of a scientific law or theory.
False
200

Hypothesis

What is the experimental group?
Garden B
200
An observation using tools and includes numbers and/ or measurements
Quantitative data
200
Give an example of a resource that would NOT be reliable in conducting scientific research.
Blog, certain podcasts, etc.
200
True or false: Laws usually don't change since they wouldn't have been adopted if they didn't fit the data.
True
300
This part of the scientific method has to be testable
Asking a question/ define a problem
300
You and your friend would like to know if lemon juice will prevent apples from turning brown. You both cut apples into equal slices. Half of the slices are sprayed with lemon juice. All slices are stored in a sealed plastic bag. After 4 days, they are observed to see how brown they turned. What is the control group in this experiment?
The apples not sprayed with lemon juice
300
What is the dependent variable?
The height of the plants
300
The group in an experiment that is "left alone"
Control group
300
When analyzing data from an experiment, you are _________________ or ___________________ your hypothesis.
Confirming or denying
300
A statement that summarizes a pattern found in nature. is known as...

400
This part of the scientific method communicates your findings to your scientific question.
Share results

You and your friend would like to know if lemon juice will prevent apples from turning brown. You both cut apples into equal slices. Half of the slices are sprayed with lemon juice. All slices are stored in a sealed plastic bag. After 4 days, they are observed to see how brown they turned. What is the dependent variable in this experiment?
The amount of brown the apples will have
400
What is the ad's hypothesis in this experiment?
The plants will grow twice as big with the special food.
400
The result of changing the independent variable in an experiment
Dependent variable
400
Why is it important do make your hypothesis after researching
Your hypothesis needs to be scientific and not random
400
A well-tested explanation for a set of observations or experimental results is known as...
Scientific theory
500
This part of the scientific method confirms or disproves your hypothesis.
Analyze data/ draw a conclusion
500
You and your friend would like to know if lemon juice will prevent apples from turning brown. You both cut apples into equal slices. Half of the slices are sprayed with lemon juice. All slices are stored in a sealed plastic bag. After 4 days, they are observed to see how brown they turned. Name 2 things in this experiment that are controlled variables (kept the same)?
The slices are the same size, all slices are stored in a sealed bag, and all slices are stored for 4 days.
500
What should the conclusion be?
2/3 of the plants in Garden B doubled their height. The special food works and the ad is correct.
500
The experiment we conduct that only tests one variable
Controlled experiment
500
Why is it important to share your results in the scientific method?
Scientists can use the information to conduct their research/ the scientific community can adapt your research as a theory or law.
500
A scientific ___ explains why things happen in science while a scientific ____ explains what will happen in science.
Theory, Law
