Color-Changing
FlowersPoison Ivy’s
Place 20-30 different drops of food coloring into each cup of water.
Now let the flowers sit next to a windowsill for about a day.
After time passes the flowers will be colored. That’s how Nature and Poison Ivy do it!
As the flowers drink up the colored water, the liquid travels up the stems and into the petals. There, the water evaporates, leaving the color dye in the petals behind. This is called transpiration.
