My class also started their lima bean experiment to answer the question: “Can plants grow without water?”Provide each student with a labeled plastic sandwich bag, one paper towel (cut in ½), and three lima beans. Ask students to carefully fold one half-sheet of paper towel in ½. Then have them lay 3 beans on the paper towel. Explain that the beans need to be in the middle and spaced apart. Next, students place their other ½ sheet of paper towel on top of the lima beans. This paper towel is also folded in half. Then, provide students with a spray bottle to dampen the paper towels. Assist as students slide their paper towel into the baggie. Show students how to leave part of the baggie unzipped to allow for air.
I recommend stapling the bottom fourth of the baggie to give the seeds a place to lie without sitting in the extra water that collects at the bottom.
