This week 3rd grade is making an experiment to know why do leaves change their colors depending of the season.
The key in this experiment is to give the leaves a good mashing, and this is always so much fun!
Leaves contain Chlorophyll. Chlorophyll makes the leaves green and is so dominant that it covers up all the other colours in the leaves. To figure out what colour a leaf would be without the dominant chlorophyll colour, we can separate the colours by doing this science experiment.
In this science experiment we used the rubbing alcohol and energy (hot water) to separate the colours. You likely saw green, and depending on your leaf type, maybe red, yellow, or orange. As we know, Chlorophyll gives leaves their green colour and is so dominant it hides the other colours in the leaves. But in the fall, chlorophyll in the leaves breaks down allowing the other colours to finally shine through and show their beautiful reds, yellows, and oranges.
