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?

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. Jordan counts the number of tomatoes produced by each plant. What is the measured variable?

• type of tomato

• size of tomatoes

• weight of tomatoes

• number of tomatoes

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.
