What is the 1st step to the scientific method?
What is Ask a Question
What is an educated statement that could be tested called?
Hypothesis
Which steps comes first in the scientific method? Hypothesis or Conclusion
What is Hypothesis
I test to see if adding nitrogen to the soil makes plants grow faster. What is the dependent variable?
The height of the plant/How much the plant grows
What is the Scientific Method?
A step-by-step process used to answer questions
Which of the following hypotheses is written correctly?
A) If a tennis ball is frozen, it won't bounce as high as one that is not frozen.
B) If I heat up a tennis ball it will bounce high.
C) Frozen tennis balls will not bounce as high.
D) If I freeze a tennis ball, then it will not bounce as high.
D) If I freeze a tennis ball, then it will not bounce as high.
Are Scientists the only individuals who use the scientific method?
No everyone can use it.
You decide if your hypothesis was correct in this step.
Step 5: Reach a conclusion
What is another word for an educated guess?
Hypothesis
What does evidence mean?
proof, or data that proves or disproves the hypothesis.
What is observation?
Careful watching and listening
During step 4, information is collected. What is that information called?
data or evidence
Before you can form a hypothesis, you need to
a. state the problem or question
b. perform an experiment
c. state a conclusion
a. state the problem or question
What step involves recording data?
Step 3: Experimenting
Before starting a science activity you should always

b. | put on an apron. | d. | get ready to do first aid. |
a. read all the instructions very carefully.
Scientists test a hypothesis by
A. | formulating questions. |
B. | designing models. |
C. | doing experiments. |

C. doing experiments.
Which of the following steps is completed last?
A. | collecting data |
b. | reach conclusions |
c. | testing a hypothesis |
b. reach conclusions
Two words that can be included in a hypothesis.
What are "If" and "Then"?
A scientist conducted an experiment to determine how the amount of salt in a body of water affects the number of plants that can live in the water. In this experiment the independent variable is....
the amount of salt in the water
How many steps are in the scientific method? What are they?
5: Ask Question, Form Hypothesis, Create Experiment, Analyze Data, Form Conclusion
In an experiment, the factor that we measure is called the
dependent variable.
I test to see if adding nitrogen to the soil makes plants grow faster. What should I keep constant?
Type of plant.
Amount of water, sunlight, soil, air the plant receives.
Location plants are tested at.
I test to see if adding nitrogen to the soil makes plants grow faster. What is the independent variable?
Nitrogen, How much nitrogen I add
