your videos are the best.please make more videos.
I really liked that experiment. It really helped me visualize what happens to the leaves in Autumn. Great video!
Glad you enjoyed it!
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!
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!
Thank you so much
The intensity of the sun ray is less in fall and winter. That also causes photosynthesis to drop drastically.
Thank you for making videos that can be used to teach students of all ages. I'm extremely impressed with your videos. Thank you!
Glad you like them!
Love 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!
+Shane Fog Hello Shane Fog....We are aiming at younger learners. But here is an explanation of how the chlorophyll is recycled. First it is broken into amino acids, then stored, then "next spring they are recycled to re-leaf the tree". See below.
Chlorophylls degrade into colorless tetrapyrroles known as nonfluorescent chlorophyll catabolites (NCCs).[9] As the chlorophylls degrade, the hidden pigments of yellow xanthophylls and orange beta-carotene are revealed. These pigments are present throughout the year, but the red pigments, the anthocyanins, are synthesized de novo once roughly
+funsciencedemos Thank you very much! That part was new to me so I just wanted to learn more about it. It is very interesting!
You are welcome, we are happy to help clear things up. Stay curious!
@@funsciencedemos I am doing a science fair on this and ik think like what should I do I got the ingredients bit your video helped me alot and I really think that u should make more vids about this for the kids can understand more I am 11 and I just learned about this yesterday and now I got more info than ever thanky u 😁😁
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?
How to preserve green colour in the leaves for a period of 1 year for which do you have any technology or chemicals.
Thank you so much for this. I've been trying to find a well explained UA-cam for my students to look at and this is just what I needed. Thanks for sharing!!!
Thank you so much for your feedback on our science video. And thanks for spreading science! Please keep in mind our channel, FunScienceDemos, has over 150 science demonstrations for every important idea in science. Here is our channel link: ua-cam.com/users/funsciencedemos . If you are a teacher, we would love to hear how you are using this video. Science is so cool!
Thank you, that is an awesome explanation.
Would this work with water as well as rubbing alcohol?
1laurasal I don't think so 😏 or will it ?!?!
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.
You also need sunlight to keep the leaf green. A leaf away from a tree will die, just like if you cut an arm from a person.
wow you saved my life!!!
so if you took a green leaf that will eventually be red, would this colour come out on the paper towel doing this experiment?
Yes, it would Stephanie...good observation!
Wow I just learnt something today!
Happy fall ya'll!!
You saved my life
2:45 "That's a lot of green stuff in those leaves!" :D LMAO
so smart kid
boiiiiiiiiii lol

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 ?
Only certain species of trees lose their green. They are a different species.
lol didn't realize this wasn't aimed at 32 yr olds. great vid none the less!
I'm 43 years old and found this video very informative and interesting !
Joseph D heck yeah science 🙌
@@dogwalk3 It goes to show you that you can never be too old to learn new things ! :)
43 same!!! ;)
@@jamieshelton274 Yeah ! ....I still look and act like I'm still 34 lol but i'm 43 really ! - I'm 9 years older then what I feel ! :)
👍👍👍
the help doing my homework so I'm probably going to get a plus I didn't copy anything
awesome
informative, educational!
When I didn't hear the answer of your imagine at the end of the video, I answered chlorophyll!
Jj
I know this answer

And I just realized it was right
