PROVING PLANTS DRINK WATER

When teachers do a unit on plants they are always TELLING kids that all plants need water to survive instead of actually showing them.  An easy experiment to prove that plants drink water is to take white flowers such as daisy’s, mums, or carnations and put them into water with a few drops of food coloring.  I use small paper or plastic drink cups, one for each color, and put one or two flowers into each. 

 I let the kids add one color to each cup. Make sure you use enough food coloring to make a fairly dark color.  I also will put a cup with plain water, no coloring and add a flower.  Within two hours the flowers start to show some color.  By day two they should have the same color as if you bought them in the florist.

Now you have proven what you have taught the children in a way that will amaze them enough to forever remember how plants drink water
