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.
