who is watching this for the science fair
1:23 is hilarious
Such a clear explanation and simple experiment, thank you. I plan to use this in my Kindergarten!
every one say hi if this is baaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaddddd
david peters, unfortunatly yes, but i sped it up so no prob. 🙂
this vidoe is soooo bad it has ligma and is bad for 13+ year olds
ligma
who is here from westpoint middle school and say hi to nate allen
this video is cancer
this is soooooooooooooooooooooooooooooooooooooooooooooooo bad
this video is cancer
your trash
very difficult for me
hi. i am a korean student. i was impressed by your experiment. i want to capture this video and use it in science club. and i want to put the course in the club cafe by using this picture. i will reveal the source. can i use your video?
Wow everything is perfect, your looks, ur knowledge, I wanna marry a Scientist
Put into strong jar with marbles and shake well.
Red leaves, science doesnt know, Just a guess, Oxidizing?

I was looking for a picture where someone made a circle of all the leaves stages from green to black.
Very extensive color range. About 5 different Greens, yellows, Orange, reds, browns.
please don't teach science
Terrible, terrible technique.
talking way too fast
way too much wasted alcohol. really bad grinding technique.
Is there a way to the separate the alcohol and the chlorophyll so it would leave a powder or paste?
what can I use instead of isopropyl alcohol ?
what is the purpose of this experiment?
David peters i am and it sucks
jk love you sweetheart
How did you get uglier with glasses dog?
She makes sense……..
This is because the isopropyl alcohol pulls the water out of the leaves through the porous membranes of the leaves by osmosis, right? And as the water is drawn out of the leaves it pulls the compounds with it, and the compounds like chlorophyll and carotenoids are drawn up the filter paper by diffusive capillary force, right?
Your kitchen setup was borrowed in v=ej2zXOwASVI.
Craaaazy idea, would the trees turn their leaves red before they fall off to help them decompose maybe? Then the tree can re-absorb them or what ever? Tree cannibalism!
I am watching for science class
how much alcohol did you use?
how much alcohol did you use?
Strictly speaking this is not paper chromatography. The solution in the beaker is just the solvent, not the mobile phase of chromatography. The trick is to choose a mobile phase which separates the different components of the mixture.
*school
i did it in shoo with some norma leaves and there were green, yellow and purple
Who is watching this for science class?
That was awesome i tried had home
Thank you! I have to do investigative project on determining if callaloo pigments are all the same and this video gave me some really nice tips on how to carry out this experiment and understand the topic.
Thank you so MUCH! 😀
Thank you so much!!! But I have a question, It can be any kind of leave????
I promise you are a life saver!!!! I take Biology online and I'm not your typical science major. This video is a great breakdown of the process for my next lab. Thanks a bunch!!
You're so cool.
Hey that was a great video…I just need to know how to graph the results
