Colored Carnations

Contributed by Leanne Guenther

colored carnations

What you need:

 

Directions:

What Happened:

Most plants "drink" water from the ground through their roots.  The water travels up the stem of the plant into the leaves and flowers.  The plant uses the water to make food.

When a flower is cut, it no longer has it's roots.  But the stem of the flower still "drinks" up the water and provides it to the leaves and flowers.

Note:  Red and blue food coloring work the fastest.

  
Our Results:

We (Tasha - Gr.3, age 9 and Kaitlyn - Kindergarten, age 5 and mommy, age 30-something *wink*) experimented with blue, yellow and green food coloring.  The blue was the fastest and the green was the slowest.  If your carnation doesn't start to show color in about 6 hours, add a few more drops of food coloring.
