Question

5. Students hypothesize that temperature is a limiting factor for the germination of seeds. They carry out an experiment to

test their hypothesis. They label two plastic bags A and B and place a damp paper towel and one bean seed in each bag.
They place one bag in a lighted refrigerator and the other bag on the windowsill. Whenever the paper towels look dry, they
add more water. Each day they check to see if the seeds have germinated and record their observations in a data table.

Which of the following is the dependent variable in this experiment?

Answer 1

The dependent variable in this experiment is the germination of seeds. By observing and recording the growth of the bean seeds in different temperature conditions, the students can determine the effect of temperature on germination.

Step-by-step explanation:

The dependent variable in this experiment is the germination of seeds. The students are testing whether temperature is a limiting factor for seed germination, so they are measuring the growth of the bean seeds in different temperature conditions - one in a refrigerator and the other on a windowsill.

By observing and recording the growth of the seeds over time, they will be able to determine the effect of temperature on germination.
