A biology student wanted to determine if using fertilizer would promote plant growth. One hundred plants were randomly assigned to one of two groups: one that used the fertilizer, and one that did not use a fertilizer. Which of the following is a benefit of having replication in the experiment?
The variables for this experiment include the number of each type of sprout, the average height of those sprouts, and the amount of compost given to each plot of land. Use the drop-down menus to complete the sentences and identify the independent and dependent variables.
More plants in the experiment should be done more than once tested on different plants change the factors Were there differences in growth between the control and experimental plants? If so, which grew taller?
In the experiment with plants being grown at different temperatures to see how it will affect a plant's growth, the control group is the plant being grown at room temperature. The experimental group includes the three plants being grown at temperatures greater than room temperature.
