Scientific Method Review: Scientific Method Review Identifying Variables Worksheet
The scientific method is a systematic approach to investigating and understanding the natural world. It involves making observations, forming hypotheses, testing hypotheses, and drawing conclusions.
Steps of the Scientific Method, Scientific method review identifying variables worksheet
1.
-
-*Make observations
Gather information about the world around you.
- 2.
- 3.
- 4.
- 5.
-*Form a hypothesis
Propose a possible explanation for your observations.
-*Test your hypothesis
Design and conduct an experiment to test your hypothesis.
-*Analyze your results
Examine the data from your experiment and draw conclusions.
-*Communicate your findings
Share your results with others.
How the Scientific Method is Used to Test Hypotheses
The scientific method is used to test hypotheses by following a series of steps:1.
-
-*State your hypothesis
Clearly state the hypothesis you are testing.
- 2.
- 3.
- 4.
- 5.
-*Design an experiment
Plan an experiment that will test your hypothesis.
-*Collect data
Gather data from your experiment.
-*Analyze your data
Examine the data from your experiment to see if it supports your hypothesis.
-*Draw conclusions
Based on your analysis, decide whether or not your hypothesis is supported.
Identifying Variables
A variable is a factor that can change in an experiment. There are three types of variables:
Types of Variables
1.
-
-*Independent variable
The variable that the experimenter changes.
- 2.
- 3.
-*Dependent variable
The variable that is affected by the independent variable.
-*Controlled variables
Variables that are kept constant throughout the experiment.
How to Control Variables in an Experiment
To ensure that your experiment is valid, it is important to control variables. This can be done by:1.
-
-*Using a control group
A group that does not receive the treatment being tested.
- 2.
- 3.
-*Randomizing the assignment of subjects
Assigning subjects to treatment and control groups randomly.
-*Blinding the participants
Keeping the participants unaware of which treatment they are receiving.
Worksheet
The following worksheet can be used to help students review the scientific method and identify variables:Scientific Method Review and Variable Identification WorksheetInstructions:
- Read the following passage and answer the questions that follow.
- Use the information in the passage to identify the variables in the experiment.
Passage:A scientist is investigating the effects of fertilizer on plant growth. The scientist plants 10 seeds in each of two pots. One pot is given fertilizer, and the other pot is not. The scientist measures the height of the plants in each pot after two weeks.Questions:
