Give each camper a small Styrofoam cup, potting soil, and a seed for your favorite plant or flower. Put it all together and add water and then put them around camp to grow. You can put them in different locations with natural lights, no light, or artificial light to see what the difference looks like when the plant grows. You can also have kids take care of their flower by adding water and keeping it in sunlight all summer long to see who can grow it the best.
