The first and second step of the scientific method are:

• Question and Conclusion

• Question and Hypothesis

• Hypothesis and Data

An independent variable is the variable that is being:

• 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

If your hypothesis supports your conclusion then you successfully completed the steps of the scientific method. If your hypothesis does not support your conclusion then you will need to redo your _______ and retest your experiment.

• data

• analysis

• question

• hypothesis
