Parts of an Experiment

Jordan is doing a science project on the effects of music on the growth of tomatoes. He has 2 plants, 1 will be exposed to classical music, the 2nd won't be around music. Which of the following would be the scientific question?

• Will tomatoes grow with classical music?

• Which plant food works best for tomatoes?

• Will music effect the growth of tomatoes?

• How tall will tomatoes get with classical music?

The number of tomatoes per plant are shown above. How would Jordan summarize the data?

• The plant with classical music grew fewer tomatoes

• Music had no impact on the tomatoes.

• The plant with music grew 35 tomatoes, the plant without music grew 55 tomatoes.

• Classical music hurts the growth of tomatoes.

What is a hypothesis for the scientific question - Does aspirin and water keep cut roses fresher longer compared to just water?

• Cut roses work well in aspirin and water.

• Cut roses in aspirin and water will keep fresh longer than using only water.

• The size of cut roses will be larger in water.

• Roses grown with classical music will be prettier.

I'm going to conduct an experiment and put roses in water and water with aspirin to see which keeps the roses fresher longer. What is the manipulated variable?

• type of liquid used

• amount of water used

• how long the roses live

• the color of the roses

• size of rose used

• type of liquid used

• color of rose

• time

I'm going to conduct an experiment and put cut roses in water, and water with aspirin to see which keeps the roses fresher longer. What is an example of a controlled variable?
