Understanding Scientific Investigations

This is your educated guess or prediction, of what you think will happen in the experiment. It is always written in "If... Then...." form.

• Hypothesis

• Conclusion

• Problem

What does replicate mean during a science experiment?

• To observe what is happening.

• To record your observations.

• To repeat, or do again.

• To share your findings.

These are the steps or directions to complete your experiment. They must be numbered and in order.

• Research

• Procedure

• Data and Analysis

• Hypothesis

An experiment to find out or solve the answer to a question.

Once you complete the experiment, you must record your results and create charts or graphs.

• Data and Analysis

• Research

• Procedure

• Hypothesis

Variables are...

• The process scientists follow to complete an investigation (question, hypothesis, materials, procedures…)

• Parts of an experiment that can be changed, and can affect the results of an experiment.

• Watching and noticing events that happen during an experiment.

• The results of the experiment showing whether your hypothesis is correct or incorrect.

Now that you have finished the experiment, you must state what you found out and tell if your hypothesis was supported (correct) or rejected (not correct).

What is an observation?

• Items you need to complete your experiment.

• Parts of an experiment that can be changed and can affect the results of an experiment.

• The steps, or directions, you take to complete the experiment. Should be in numbered order.

• To watch and notice what is happening during the experiment/investigation

Before you make an educated guess about what will happen in the experiment, you have to be educated. You must find out information about your topic.

• Data and Analysis

• Research

• Conclusion

• Problem

What is the Scientific Method?

• The steps, or directions, you take to complete the experiment. Should be in numbered order.

• The process scientists follow to complete an investigation (question, hypothesis, materials, procedures…)

• The information you collect from the experiment (usually in charts and graphs, using numbers).

• The results of the experiment showing whether your hypothesis is correct or incorrect.
