As the summer is coming, kids would notice that the leaves change gradually. Today, the alpha science classroom would do the Leaf Color Experiment with kids. It would be absolutely one of my favorite natural science experiments for kids. It is easy and kids can learn the leaf colors. You cannot miss the test tube science activity.

Alpha science classroom：Leaf Color Experiment Step-by-step tutorial
First, children put four leaves into a pot of boiling water. Boil the leaves for 5 minutes. Make sure that an adult supervises this step!
While children wait for the leaves to boil, fill the test tube with rubbing alcohol (or a goblet is fine). Children need enough rubbing alcohol to soak the leaves.
After the children waited for the leaves to boil for 5 minutes, they picked up the leaves with tongs and quickly put them in rubbing alcohol.
the fourth step
Children pay attention to the current color of rubbing alcohol. Now wait about an hour and observe what happens to the leaves and alcohol. What do you see? Let your Leaf Color Experiment sit overnight, and then come back to see if your alcohol color has darkened. Can you guess what color these leaves are?
Alpha science classroom: The scientific principle of Leaf Color Experiment?
The alpha science classroom tells the children that leaves are full of chlorophyll, which can convert the sun's energy into plant food. Chlorophyll also makes the leaves look green. They also have other colors, but as long as there is a lot of chlorophyll, green will hide all other colors. However, in autumn, the chlorophyll in the leaves begins to decompose. This allows other colors (such as yellow and orange) to appear!
Magic chlorophyll can change the leaf’s color and kids also find the natural science mystery. The Leaf color experiment from the alpha science classroom is successful. If you want to know more about natural science experiments, please follow us.
Alpha science toys have made many kids science experiments kits for kids to help them explore the magic natural world to be the best science guy.
