Every day at work, Greta poured a large cup of tea that she drank
throughout the morning. She wondered how much bacteria might be
growing in her cup of tea as the morning went on. To find out, Greta filled
three identical cups of tea and placed them on her desk for three hours.
After the first hour, she placed a drop of the tea from each cup on a
separate microscope slide and counted the number of bacteria in the drop.
Greta repeated this with each cup of tea after the second hour and again
after the third hour. Identify the dependent variable in the experiment.
The time allowed between testing the drops
O The location of the cups of tea that were being tested.
The number of bacteria in each drop of tea
O The number of drops of tea used in each sample
