Check back every Monday for a new Bite Sci-zed chunk of science!

All experiments should be performed with responsible adult supervision!

  1. 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?

  2. 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.

  3. 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?

  4. 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.

  5. 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! 😀

  6. 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!!
