We have been busy in science!
After classifying items as either living or nonliving, we furthered our study of plants by doing an experiment with lima beans. We put 5 lima beans in a bag with a moist towel and some air. This bag was taped to a sunny classroom window. These lima beans had water, food (sunlight) and air- all properties a living thing must have in order to grow and change. The next bag of 5 lima beans was placed in a bag, but was then put in a dark closet. These beans did not receive water, food (sunlight) or air, and were therefore not given a chance to grow or change.
The scientists recorded their hypotheses in their journals- what would the beans look like in a week? Here are some initial photos.

I'm impressed with the experiment you did with lima beans! And the children look so motivated!
I’m retired now but taught for many years. In my combined first and second grades, we also did experiments with Lima Beans, but with another approach. Please see my blog for experiments with Lima Beans that I did for years. Children really loved these experiments.

Cool experiment!
I am an elementary/middle school teacher and I have another bean experiment my kids love. Grow a TickleMe Plant. It is the only plant that the kids can interact with as it closes its leaves and lowers its branches when tickled. You can do the same water or not controlled study with this plant or see The TickleMe Plant Book for many more. Just search on line or visit http://www.ticklemeplant.com to see a TickleMe Plant moving.
