Question

Mary wanted to know if seeds needed water to start growing or if any kind of liquid would work. Mary set up several experiments to find out. She used radish seeds, paper towels, plastic bags, and different kinds of liquid in her experiment. Mary put three seeds into each bag. She then used 30mL of liquid to wet a paper towel and put a different paper towel in each bag. Mary put all of the bags on the same table next to a window so that they could each get the same amount of light. She waited three days and then checked her plants.

Answer 1

Answer:

independent variable: 30mL of liquid to wet a paper towel

dependent variable: how much the plants grow if at all.

control: they all received the same amount of light, that or the paper towels are the same.

experimental group: It's not stated that she did indeed use water, but there is a need for a control group, if so, then it's the other 2 groups that didn't use water, also because I can't think of anything else.

control group: The groups that used water rather than the other 2 plants.
