so if you took a green leaf that will eventually be red, would this colour come out on the paper towel doing this experiment?

I really liked that experiment. It really helped me visualize what happens to the leaves in Autumn. Great video!

The intensity of the sun ray is less in fall and winter. That also causes photosynthesis to drop drastically.

How to preserve green colour in the leaves for a period of 1 year for which do you have any technology or chemicals.

[suzannearchibald]

Wow! I appreciate your clarity. Our Pre-K will be able to grasp this concept thanks to your presentation. As a teacher, I especially liked your "secrect ingedient" approach. Very effective! Keep up the good work!

Mmm if those leaves change colors due to lack of light, why places like the West, California per say, don’t suffer the change of color ?

Thank you for this video! My 4 and 5 year old are now able to understand why leaves change colors! This was a wonderful way to explain it!

Great video! I am curious about the part where you said the chlorophyll was being drawn into the tree and stored. Do you have a source where I can learn more about that? Thanks!

[terrianakrize]

the help doing my homework so I'm probably going to get a plus I didn't copy anything

My son watched your video and asked this, if i cut a green leaf it also turns yellow. There is not tree retrievieng clorophile. So must be another way. Thanks.

[supriyasarkar]

I understand from your words that if we put green leaf in the alcohol becomes yellow or brown in the sense of alcohol loses green color?

[laurasal]

Would this work with water as well as rubbing alcohol?

[moonlightgaming]

When I didn't hear the answer of your imagine at the end of the video, I answered chlorophyll!

[arizonabarb]

Thank you, that is an awesome explanation.

[fionawalker]

Thank you so much for this. I've been trying to find a well explained Youtube for my students to look at and this is just what I needed. Thanks for sharing!!!
