Scientific Method

The first and second step of the scientific method are:

• Question and Conclusion

• Question and Hypothesis

• Question and Experiment

• Hypothesis and Data

An independent variable is the variable that is being:

• Analyzed

• Tested

• Controlled

• Measured

A dependent variable is the variable that is being:

• experimented on

• measured

• tested

• controlled

A control variable is the variable that is:

• controlled and measured and stays the same between experiments

• controlled and tested and stays the same between experiments

• controlled and stays the same between experiments

• controlled and analyzed and stays the same between experiments

I create an experiment to measure which brand of sponge can absorb the most water. I use 3 different brands of sponge, 3 of the same beakers filled with 30 mL of water from the faucet at room temperature. What is the independent, dependent, and control variable. Select 3 options.

• how much water that is absorbed is the dependent variable

• the water is the independent variable

• the brands of sponges are the independent variable

• the beakers are the control variable

• the water from the faucet is the dependent variable

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

• conclusion
• procedures
• materials
• responding variable

A testable prediction about a scientific investigation is a(n)

• Question
