Scientific Method/Variables

Reorder the following

• Experiment

• Analysis

• Conclusion

• Hypothesis

• Research

A control ________ is not experimented on and is used for comparison.

A _____________is an educated guess about the answer to a question.

An ​ (a)   is designed to test a hypothesis. In an experiment, there are typically ​ (b)   variables.

• three
• experiment
• hypothesis
• independent
• dependent
• collect data

Why is it important to have a constant variable throughout our experiment?

Why is it important to conduct scientific tests more than one time?

Ready for a brain teaser? Here it goes: Which kind of questions are beyond the reach of scientific methods to solve?

• Is it questions about the mysteries of outer space?

• Or questions about the enigmatic deep ocean?

• Could it be questions about the complex world of ethics?

• Or is it questions about the fascinating history of Earth?

Imagine you're a scientist conducting an experiment. Which variable would you be keenly observing or measuring?

• A constant, unchanging factor

• A controlled, regulated factor

• A dependent, outcome-based factor

• An independent, influencing factor

Imagine you're John, a budding scientist, conducting a thrilling experiment to see how different types of soil affect plant growth. You've got your independent variable (the soil type) and your dependent variable (the plant growth). Now, in this exciting scenario, what would you consider as your control variables?

• Are they the factors that you, as John, are measuring?

• Or, are they the factors that you, as John, are changing?

• Maybe, they are the factors that you, as John, are observing?

• Or, could they be the factors that remain constant throughout your experiment?

Imagine you're a scientist conducting an experiment on plant growth. You've just finished your experiment and now you're trying to figure out if the results support your initial prediction. What are you doing?

• Are you drawing conclusions?

• Are you forming a hypothesis?

• Are you making observations?

• Are you asking questions?
