A student wants to see if fertilizer would really help plants to grow. She had 2 identical bean plants. In Plant A she put fertilizer with normal soil. In Plant B she just put normal soil. She watered both plants daily with 1 cup of water and both plants were in the same room with the same amount of light. What was the Control in the experiment?

• the water

• the light

• Plant B

• the fertilizer

She watered both plants daily with 1 cup of water and both plants were in the same room with the same amount of light. What is the one thing the student could do to improve the experiment?

• use different types of plants

• Add fertilizer to the soil in Plant B

• Perform the experiment multiple times

• Place one plant nearer to the window
