1.2a The Scientific Method

Which of the following statements best describes a prediction?

• The number of deformed frogs in 5 ponds that are polluted with chemical x is higher than the number of deformed frogs in 5 ponds without chemical x.

• If the water in a pond has lower levels of pesticide then there will be fewer deformed frogs.

• The number of deformed frogs is not affected by the presence of chemical x in the pond.

"If the fertilizer is added to the soil in a garden then the plants growing in the garden will grow taller."

Which of the following does this statement represent?

• hypothesis

• observation

• evidence

• prediction

Which statement best describes a hypothesis?

Statement A: If fossil fuel burning increases, then atmospheric carbon dioxide will increase.

Statement B: The increase in atmospheric carbon dioxide is due to an increase in the amount of fossil fuels that are being burned.

• Statement A

• Statement B

• Both Statement A and Statement B

"The height of plants grown in a garden that are provided fertilizer is higher than the height of plants grown in a garden not provided fertilizer."

Which of the following does this represent?

• experiment

• prediction

• evidence

• hypothesis

In which step of the scientific method do you test the hypothesis?

• Observe

• Experiment

• Analyze

• Conclude

The summary at the end of an experiment that explains the results. 

• conclusion
• procedures
• materials
• responding variable

The information that you gather from your experiment that you will organize into charts and graphs:

• observations

  conclusion

• data

• variables

• hypothesis

What is the first step in the scientific method?

• Ask a question

• Conclusion

• Form a hypothesis

• Make an observation

"Why is the sliced cheese all moldy?"

Which step does this question represent in the scientific method?

• make a hypothesis

• draw a conclusion

• ask a question

• experiment

At the end of the scientific method, scientists should always:

• share what they learned and their results with other scientists

• make a bar graph

• celebrate if their hypothesis was correct

• keeps their results secret to their ideas do not get stolen
