What is the first step of the scientific method?
Draw a conclusion
Ask a question
Record data
Form a hypothesis
A hypothesis is best described as:
A proven fact
A testable explanation or prediction
A random guess
The data you collect
Which of the following steps comes *after* forming a hypothesis?
Analyze results
Conduct an experiment
Ask a new question
Share conclusions
The purpose of conducting an experiment is to:
Prove your hypothesis correct no matter what
Test your hypothesis
Avoid collecting data
Eliminate observations
When you make observations during an experiment, you should:
Ignore unexpected results
Record data carefully and accurately
Only write down what supports your hypothesis
Change your data to match predictions
What type of observation uses numbers and measurements?
Qualitative
Quantitative
Descriptive
General
Which of the following is an example of a qualitative observation?
The plant is 15 cm tall.
The water temperature is 25°C.
The leaves are green.
The block weighs 200 g.
A variable in an experiment is:
Something that stays the same
A factor that can change
The data collected
The conclusion
The variable that a scientist purposely changes in an experiment is the:
Dependent variable
Controlled variable
Independent variable
Constant
The variable that responds to the change in the experiment is the:
Independent variable
Dependent variable
Controlled variable
Constant
Constants in an experiment are:
Factors that stay the same
Factors that change
Data collected
The hypothesis
A control group in an experiment is important because:
It allows multiple variables to change
It provides a standard for comparison
It always proves the hypothesis
It collects more data
In an experiment testing the effect of sunlight on plant growth, what is the independent variable?
Plant height
Amount of sunlight
Amount of water
Type of soil
In the same experiment, what is the dependent variable?
Amount of sunlight
Plant height
Amount of water
Type of soil
Which of these should remain constant in a plant experiment?
Type of plant, soil, and pot size
Amount of sunlight and water
Growth of the plant
Height of the plant
Why do scientists repeat experiments?
To make the results look better
To check accuracy and reliability of data
To test different hypotheses at the same time
To avoid sharing results
Which of the following is an example of a good scientific question?
Why are flowers pretty?
What color is the best?
Does fertilizer make plants grow taller?
Is pizza better than hamburgers?
What does analyzing data help scientists do?
Form a conclusion
Skip the experiment
Change the hypothesis to match results
Eliminate constants
If your hypothesis is not supported, you should:
Hide your results
Make up new data
Revise your hypothesis and test again
Stop doing science
Which of these shows proper scientific procedure?
Changing multiple variables at once
Testing one variable at a time
Recording only positive results
Avoiding constants
Which statement about the scientific method is true?
It always follows the exact same order without changes
It helps scientists organize and solve problems
It always proves the hypothesis correct
It avoids observations
In an experiment, the group that receives no treatment or the normal condition is called:
Control group
Dependent group
Independent group
Variable group
What should be included in a good data table?
Only the results that support your hypothesis
Labels, measurements, and units
Pictures instead of numbers
Conclusions instead of results
Which of these is an inference, not an observation?
The sky is cloudy.
The leaves are wet.
It rained earlier.
The ground is muddy.
A student notices that a ball rolls faster on a smooth surface than a rough one. Which step of the scientific method is this?
Observation
Hypothesis
Experiment
Conclusion
Which of the following would be the best tool to measure liquid volume accurately?
Ruler
Thermometer
Graduated cylinder
Balance
Which of the following best describes a conclusion?
A summary of the experiment and results
A guess at the beginning
Raw data collected
A set of constants
Which step of the scientific method might lead scientists to do more experiments?
Asking a question
Drawing a conclusion
Sharing results
Analyzing data
Why is it important to only change one independent variable in an experiment?
To save time
To make the data look correct
To ensure accurate results
To simplify the experiment
Which of the following is NOT a part of the scientific method?
Asking questions
Forming a hypothesis
Ignoring data that doesn’t fit
Conducting an experiment
When going through the process of the Scientific Method it is often necessary to (a) steps.
Label the steps of the scientific method in order.
Research
Experiment
Hypothesis
Conclusion
Purpose
Data Analysis
Label the descriptions that go with each step of the scientific method.
Use outside sources to find more info
Gather, organize, & evaluate data
Predict the answer to the problem
What is the problem?
Develop a procedure to test hypothesis
Was your hypothesis correct?
Match the following
Formulate a hypothesis
Coach thinks the new kind of paint will last longer than the usual paint.
Gather/Research information
Coach goes to the hardware store to read labels in order to compare the paints.
Conduct an experiment
Coach paints one field with the usual paint, a field right next to it with the new type of paint.
State a conclusion
Coach decides the new paint lasts longer than the usual.
State a problem/ Ask a question
Will the new type of paint last longer than the usual paint?
What we make different in an experiment that causes something to occcur
Independent Variable
What we measure in an experiment. This is the "effect"
Dependent Variable
What we keep the same in an experiment or the results are thrown off
Controlled Variable
Match the following word with it's definition:
Independent Variable
Factor That Is Adjusted By The Experimenter.
(x-axis)
Dependent Variable
Factor Whose Value Depends On The Independent Variable.
(y-axis)
Science
Process That Uses Observation and Investigation To Gain Knowledge About Events in Nature.
The variable that is measured in an experiment is called the (a) variable.
The variable that must be controlled or kept the same in an experiment is called the (b) .
The variable that is changed on purpose in an experiment to test something is called the (c) variable.
Match the following
Independent Variable
Always tested
Dependent Variable
Results of the Tested Variable
Control Variable
Not tested
What do scientists do after they conduct the experiment?
Make an observation.
Record and analyze the data.
Ask a question.
