THE CELERY STALKS AT MIDNIGHT!

After everyone left and I finished visiting with a former student (he played one of the soldiers in the Boston Massacre movie that we watched together), I had a chance to set up a demonstration of what we read about plants earlier this week.





We read in our science textbook that plants pull water from their roots, up the stem, and to the leaves through tiny tubes. The tubes are so small that the water is actually pulled through the tubes! This action is called capillary action, and we'll discuss capillaries in more detail later when we talk about the circulatory system.





Anyway, I followed the procedure (and learned a little more about a famous Indian scientist named Jagadis Chandra Bose) for a demonstration of capillary action that we'll see on Monday. If you are interested in trying the demonstration out at home (and being able to predict what the class will see before Monday), please follow this link:

I have placed six pieces of celery (three with leaves, three without) in colored water (morado, azul, y rojo). Two leafy celery pieces have been bisected vertically (up to the leaves), and one has been cut enough that the bottom of the stalk is submerged in each color. What do you think will happen to the leafy celery? What about the other stalks that are placed in each color but have no leaves?

Sorry about the off-center images!

Thank you BOO! Writer and family for donating the celery!
