BRIDGEPORT, W. Va. (WDTV) - We had our science lesson on why leaves change colors. Now it's time for the experiment.
I went outside and got a few leaves from the same tree. Now I cut these up into very small pieces and put them in a jar. Pour rubbing alcohol in until it covers the leaves. Mash up the leaves really well and then put the jar in a bowl of warm water. Finally cover it with cling wrap or a plastic bag and wait 30 minutes.
After 30 minutes, come back and the leaves should be breaking down and turning the solution green. Next take a strip of filtered paper, im using a coffee filter, rest it in the solution and now wait again. This time at least an hour.
After you wait at least an hour, take out your paper and depending on your type of leaves, you'll see green working up the filter and for me I also saw some yellow.
The rubbing alcohol broke down the leave and separated the compounds within it. Like I explained in the previous Kate's Corner, leaves are green because of the chemical called chlorophyll but there are also other chemicals in the leaves. One of those chemicals make the leaves yellow and are always there but the green just covers them up. Since the different compounds react with the filtered paper differently, the green doesn't go as far up the paper as the yellow does.
Be sure to share a photo of your filtered paper when you do this experiment!
