Experiment With What a Plant Needs to Grow

Russ puts three bean plants on a windowsill. He waters the plants daily, measuring in milliliters (mL). The plants are watered the following amounts daily: plant A – 0 mL plant B – 10 mL plant C – 25 mL plant D – 50 mL Russ measures the height of the plants every week. This table shows his results in centimeters (cm). Which best describes how much water young bean plants need every day?

• 0 mL

• 10 mL

• 25 mL

• 50 mL

Grace wanted to see if her plants would grow faster if they were placed under an artificial growing lamp instead of sunlight. She placed half of her plants in a room with two windows and an artificial growing lamp. She placed the other half of the plants in a room with six windows. What is one major mistake Grace made when setting up this experiment?

• The plants receiving light from the artificial lamp were placed in different sized containers.

• All of the plants received equal amounts of fertilizer.

• All of the plants were watered the same amount.

• She used two different kinds of plants
