Celery experiment this easy science project is as good to be done with preschoolers and kindergarten kids, as with grown up children in the lab, or at science fairs it is a great activity to make the concept of how plants get their nutrition from the soil clear to the young, ever-inquisitive chaps.
Here's a set of science journal pages for studying osmosis with the colorful celery experiment. In this lab experiment, students will be able to relate the scientific concepts of diffusion and osmosis to real life situations and the environmental needs of plant and animal cells students will understand the basic mechanics of passive transport and how it relates to the functioning of a cell's membrane. If cut celery stalks are placed into water, then water will go into the celery by the process of osmosis to easily see whether or not water goes into the celery, this experiment uses colored water if the color is visible in the celery then water has entered the plant's cells. Lab #5: osmosis, tonicity, and concentration background the internal environment of the human body consists largely of water-based solutions.
