    As a university student of biology, and now a student-teacher of biology. I seriously can't thank you enough. I've watched your videos for years as a resolution to my educational frustrations. You're the man, Mr. Anderson. Can't wait to get this lab going with my high school students.

    Thank you kind sir, I have been stuck with a college bio lab at the last week before the semester since the person that had agreed to do it backed out. I have taught the lecture for several years, but this is new and I am scrambling and can't find a supply of rennet or rennilase for the lab I was going to do, so this will be a fabulous replacement integrating the sci method testing different wattages or distances from the heat sink.

    Would anyone know the purpose of pushing on the syringe after you have pulling on it? We did this lab a couple of weeks ago and nobody in our class was able to get the leaf chads to rise after sinking them in the syringe. I was surprised at how fast those leaves sank for Mr. Anderson as when I was duplicating the experiment, I spent upwards of 10-12 min creating the vacuum in the syringe to sink even a few chads.

    @mr.l6332 6 років тому +2

    Can someone explain to me how the leaves generate oxygen bubbles without carbon dioxide? Mr. Anderson said all gas is removed from the leaf during the syringe step, so that would mean CO2 got removed too. Is there still CO2 in the leaf chads? Or is the oxygen producing step not reliant on CO2?
    Edit: I figured it out but decided to leave the comment here for anyone else who had the same thought.
    The light dependent reactions of photosynthesis are the ones that make O2 and the only input is air and light. So yeah. The step that needs CO2 is the Calvin cycle.

    Hi Mr. Anderson- My class did this lab, and I'm having trouble determining the dependent & independent variables, and the control. I assumed that the dependent variable was the number of chads, the independent variable was the amount of 02 in the chads when exposed to sunlight, and that the control was the amount of liquid in each cup. Is this correct? Thanks again for making these videos, they make bio so much more understandable!

    • @catapatata
      @catapatata 2 роки тому +2

      9 years later, maybe for another student... This is not an experiment, it is actually the control. You have to compare this with another condition, which is your independent variable (amount of light, color of the light, temperature, etc). Then what you measure (the time at leaves start to float) is your dependent variable (which is proportional to the amount of O2 or photosynthesis rate).
      Sorry if my english is wrong.

    • @photilal1960
      @photilal1960 8 років тому +4

      +Calypso Calypso Photosynthesis. The process that happens in the syringe pulls the air out of the leaf chads, then by creating a vacuum with the solution, it causes the Carbon Dioxide in the solution to be sucked in, replacing the air. When placed in the sodium bicarbonate under a lamp, photosynthesis starts and releases the byproduct of Oxygen, which increases the buoyancy of the chad and makes it float. We just did this lab in my class.

  • @plaineblack
    @plaineblack 8 років тому

    As I watched bubbles start to form on the leaf, I started wondering...how can you be sure that the bubbles aren't from the water - dissolved CO2 or O2 that was is the water in the first place? Could the leaf be providing nucleation sites for dissolved gases to grab on to? (apologies if this has already been asked and answered)

    • @Digm4
      @Digm4 8 років тому

      It's from the leaf because when it rises it starts to gain weight which makes it heavier and therefore rise to the top. It rises because it's taking in the carbon dioxide and producing oxygen from it. These bubbles would not form if it was not actively in photosynthesis.
