Chris wanted to determine the effects of a soil pollutant on the growth of a sunflower plant. He designed an experiment and recorded his results in the data table. Where does Chris make a mistake in the design of his experiment?

• The amount of water should be the same for each plant.

• The amount of sunlight per day should be different.

• The amount of pollutant should be the same for each plant.

• The experiment should use more types of plants.

Jane is setting up an experiment involving bean plants. She places a bean inside a damp paper towel, then places it inside a Ziploc bag. She takes another bean but places it inside a dry paper towel. She tapes both Ziploc bags to her classroom window next to each other. She checks each day to observe and record the data. Jane is most likely invesitgating which hypothesis:

• Beans cannot grow in a paper towel.

• Amount of sunlight affects how fast beans grown.

• What does a bean look like once it's sprouted?

• A dry bean grows quicker than a damp bean.
