3 green leaves from the same tree
Paper coffee filter
A small container
Plastic baggie (or plastic wrap)
Now Follow These Steps:
First: Break the leaves into tiny pieces and put in the glass jar, pour in enough rubbing alcohol to just cover the leaves
Second: Stir the leaves and rubbing alcohol until the alcohol turns green.
Third: Cover your jar with a plastic baggie/wrap then place the jar into your small container and pour hot water into the container. Wait for 30 - 60 minutes but stir the leaves periodically by swishing the jar. The alcohol should become a very dark green color.
Next: Cut a strip of the coffee filter a little longer then the depth of the jar. Place it in the liquid and leaves and tape the strip to the edge of the jar.
Here’s What’s Happening!
In this fall science experiment we used the energy caused by the heat of the water along with rubbing alcohol to the separate the colors in the leaves. What colors did you see? Red, yellow, orange?
Chlorophyll gives leaves their dominant green color, blocking the other colors until the autumn. In the fall, changes in the length of daylight and temperature stop the leaves food-making process. When chlorophyll breaks down the green color disappears which then allows the other colors to appear. Read more about this process here http://www.esf.edu/pubprog/brochure/leaves/leaves.htm
