Keesha did an experiment to study the rate of photosynthesis in the water plant Elodea. She placed a piece of Elodea in a beaker of water and set the beaker 10 centimeters (cm) from a light source. Keesha counted the bubbles released from the plant every minute for five minutes (min). She repeated the process two more times. First, she moved the light to 20 cm from the beaker, and then she moved the light to 30 cm from the beaker. What is the outcome variable (dependent variable) in this experiment? What is the key phrase that tells you what you are looking for?

Respuesta :

What is the outcome variable in this experiment?

The dependent variable which is the outcome of bubbles produced.

Keesha did an experiment to study the rate of photosynthesis in the water plant Elodea.

My guess would be that since we initially know what the experiment is for, the key phrase is:

Keesha counted the bubbles released from the plant every minute for five minutes (min). She repeated the process two more times.

The outcome of the bubbles that are produced will be the dependent variable.

  • In an experiment, the variable that the researcher is testing or being measured is known as the dependent variable. For example, if a study is carried out on how tutoring has an effect on the test scores of students, in this case, the test scores of the participants will be the dependent variable.

  • Regarding the information given in the question, the outcome of the bubbles that are produced will be the dependent variable. The outcome of the bubbles is being measured by the researcher, therefore it's the dependent variable.

In conclusion, the key phrase that's vital in knowing what Keesha is looking for was "Keesha counted the bubbles released from the plant every minute for five minutes".
