A scientist is investigating how matter flows into and out of a plant. In one experiment, the scientist places a potted plant by a sunny window. The scientist plans to water the plant every day for two months.

Which additional three steps would be most useful for the scientist to follow in the experiment?

Select the three correct answers.

• Measure the mass of the plant and pot, both before and after the experiment.

  
  

• Measure the mass of water added to the pot each day.

  
  

• Measure the mass of the soil alone, both before and after the experiment.

  
  

• Observe the temperature outside each day.

  
  

• Measure the temperature of the soil every day.

A science student claims that the mass of a plant comes mostly from air and water.

Could investigations of photosynthesis provide evidence for this claim?

• Yes. Data show that photosynthesis takes up carbon dioxide and water.

  
  

• Yes. Data show that photosynthesis depends on the energy of sunlight.

  
  

• No. Photosynthesis is a process that involves energy, and is not related to the mass of plants.

  
  

• No. The claim of the student is false, so it cannot be supported.
