A biologist is testing the effect of an antibiotic on the growth of a colony of bacteria, using 5 petri dishes. One petri dish is not treated with the antibiotic, so it is called the:

• Control group

• Experimental group

• Independent variable

• Testing group

In an experiment, a scientist has multiple plants. Each plant is treated with a different fertilizer, except one group that is left alone. Each plant is the same species and roughly the same age. They are stored in the same conditions. The researcher measures each plant to see how much they grow over 2 weeks.

What is the independent variable?

• The plant growth

• The different groups

• The type of fertilizer applied

• The group that is not fertilized.

In an experiment, a scientist has multiple plants. Each plant is treated with a different fertilizer, except one group that is left alone. Each plant is the same species and roughly the same age. They are stored in the same conditions. The researcher measures each plant to see how much they grow over 2 weeks.

Which is a constant in the experiment?

• The fertilizers

• The different groups of plants

• The amount of plant growth

• The plants are all the same species
