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.
@@WeAreBlank18 It's not really stealing. It's an incredibly common experiment and one of the easiest ways of measuring rate of photosynthesis. So common in fact, that it has its own measuring unit called ET50.
Summary of video: if you put light over plant cells, they can see the camera you are recording with. So, they fly away from the view out of embarrassment. You're welcome for this true level of scientific knowledge.
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.
I was forced to watch this as part of our pre-lab for our own Photosynthesis experiment... I am really tired as I procrastinated, and I just wanted to get it over with _(side note: it was easy as took like 15 minutes)_ I watched this vid expecting to be bored, but I actually found it really interesting. Hope I do good at the lab tomorrow.
Today's my birthday and I didn't feel like creating a flowchart and copying down a procedure in my notebook! You saved me a good deal of time! Great pre-op! Thanks!
Thanks for the video. Me and my teammates are looking for an experiment about photosynthesis and we're so out of ideas on how are we gonna put an experiment of it. Then my friend saw this video and it really helps... Now we're gonna use this for our experiment... The chads floating is fantastic... I like it :)
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.
I understand that the rate of photosynthesis is the independent variable and ET50 is the dependent variable. But I'm unsure of how to determine the rate of photosynthesis of ET50. Please help!
I have been struggling ever since my pet dildo died, his name was henryetta. Also I was just diagnosed with stage 69 aids, but this video was legit the second cumming of christ. Keep up the good work Daddy Anderson. #courageous #riptompetty
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!
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.
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.
Great video! It helps but you are a few labs behind us. It seems that I turn in a Lab Report a week before your video on that lab comes out! We just finished the Mitosis and Meiosis Lab in my class Of course no need to change the way you do things for one class. Much appreciated! Every time I watch one of your videos I feel like I am getting 1 step closer to getting a 5 on the National Exam Thanks again!
+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.
can you show me how to graph and chart the results when you use 3 types of light, and you have with CO2 and without CO2 and you have to include the seconds
I'm planning to conduct a similar experiment in class but I have one question: doesn't the presence of bicarbonate have an effect on the pH? Can this be marginalized?

Evan Shanes sorry to hear that buddy
This was actually assigned for homework, the mediating leaves at the end made this worthwhile.
same bro
4 years later and they still steal the work from better teachers, that's why I'm here, homework.

@@WeAreBlank18 Congrats bro, did you do any more biology in college?
The award for most appropriate choice of background music goes to...
The one dude who had hillbilly farmer music for the headphone review
When the beats drops at 6:08 and the chads start rising... #beautiful
Thank you so much
damn straight kiddo
me
whats the name of the music
chad
Mr Anderson you are saving my life in AP Bio :)
Brittany Gillespie oh snap
She jot
Hot
Same except its this year
bruh we're learning this in our basic bio class
The first chad starting to rise at 6:09 was so dramatic, especially with the cymbal crash in the background
find your cat
JerusalemStrayCat the music really adds so much.
"I must go my planet needs me"
No one:

The end helps relieve stress!

You're welcome for this true level of scientific knowledge.
My entire class got them to sink, but no one got them to float. We unanimously decided to pretend it never happened.
That music tho :DDD
It brought the biggest grin on my face. It just made the floating leaves both glorious and ridiculous.
Jan M. Jackie chu sml
I drank the water and idk what was in it so I came to this video thank god its just baking soda
what were you thinking
HAHAHA
Lmao😂😂😂😂
Wouldn't want to damage your brain cell
Did this for my Hw Thanks 🤣

Apparatus list:
• Hole punch
• 1 leaf
• 100 ml of water
• Syringe
• Beaker
• LED light
• Stopwatch

My students always cheer the chads as they rise- it is great to watch!
Ooh, I like the music!
Got a biology assignement about this experiment. Thanks for the well explained and comprehensive video!
The only reason why I am passing AP Bio thank you
Mr. Andersen...Thanks for making me love Science...

Everbody gangsta till the leaf starts to ascend
How have I never seen this video before, yet it seems so iconic?
@zombiegirl775 It was a stock clip from Apple's iMovie.
Thanks a lot sir. These lab videos are really a blessing!
Thanks! Helped me a lot for lab tmrw!
Master Shifu could never.
Excellent educational tools....yaa for eSciencelabs!!!Go Nick!
whats the name of the song played when the leaves are beginning to float?

try 2024😭😭
so awesome. I wish you were my bio teacher.
One of best ans practicle
great work
@LayPhysicist I think so too. I could watch floating chads forever. :)
I’m dying 😂 someone added this video to a $uicideboy$ playlist
Super informative video tho I can’t lie
Thank you mr. Bozeman Science. I will be doing this for my botany online class.
So if you punch a leaf disk across a vein,is that gonna impact the results?

Pushes the water into the leaves
Thank you! You have made the written lesson plan I inherited make sense.
That video was oddly relaxing and calm.....IT WAS MEGA AWESOME!
6:07
Chad: "I must go now. Farewell."
Man! Thanks! I love you! All my biology 9 class loves you so so much! my teacher is Brennan Van Loo, he also loves you. We adore what you do! XOXO
The chosen one has been selected!
I understand that the rate of photosynthesis is the independent variable and ET50 is the dependent variable. But I'm unsure of how to determine the rate of photosynthesis of ET50. Please help!
This was brilliantly and beautifully explained, Good Sir. Thanks ! : )
The music choice bro??? Am I watching a photosynthesis lab or learning the way of inner peace from a Japanese monk? 😭🙏
the photosynthesis occurs in the leaf chad and they produce O2 in the leaf cavity, increasing their buoyancy, thus rising it up

But there is CO2 in the water....
jk dont do this fucking lab, its hard af
the leaves: doing photosynthesis
me: vibing to the background music
Ooops here where I understand the photosynthesis thourghly ... Great great job... Really thumbs UP ;)
Good video. I would like to suggest your get a camera that records higher resolution, it was a litte hard to see clearly
i just ate some spinich chads for lunch today, thanks mr anderson!
Thank you SOOO much for this tutorial!! This helped me pass AP Biology :DD My
P.S : I love Leaf Chads
whats the song ypu had for the sped up part
Lmao, that music, so deep. xD
Love your videos. Cool music.
Dat asian music at the end though :3
Hail Mr Anderson
5:20: Showing this video to my students to instill a sense of wonder!!!
One question, do you think that i could use this experiments, for proving that light is needed in the photosynthesis? :)
lol, the leaves at the end tho. that made my morning
The video quality may be bad, but the content is great!
The song when the chads start to rise: The Global Chill. At 5:58 in the song.
How about a shortened version of the video with just the floating chads that we could play on a loop so the students can watch it while they work!?
Adding this to my favorites because of the ending xD
Great video! It helps but you are a few labs behind us. It seems that I turn in a Lab Report a week before your video on that lab comes out! We just finished the Mitosis and Meiosis Lab in my class
Of course no need to change the way you do things for one class.

Thanks again!
What kind of syringe was used?
brilliant experiment!!!
Beautiful :,D Thank you Mr. Anderson!
@NDfan369 how many AP classes are you taking?
I got a question. Why some of the chads "rise up" faster than the others?
What is the name of the end music so I can remember it and listen to it over again
Kai Umeda darude sandstorm
I need to do this at home, can I just use filter water instead of distilled?
What an amazing experiment! Go science. Where did you find this?
MUSIC?
how long did it take for the leaf to float off the ground?
That leaf chad... That leaf chad is the chosen one...
music in the end i rate 5 stars
May I know why I cant get it float after i success to make it sink. Shall I put under sunlight
love u mr bozeman
mr. anderson :)
I have a question
is i try using boiling water instead of using lamp and the plant and it float
plz answer
@@pascualsofia5882 no, you need light shining on the leaves or it won't be able to perform photosynthesis.
What wattage lightbulb did you use?
So what actually causes the leaf chads to rise

Is there a way to do this without a syringe ?? PLS HELP! My lab TA will not approve a syringe for my groups experiment
I used "the force" with my hands to raise the chads on screen. It was beautiful.
Lol the music gets faster and harder as it starts to float.. perfect.
i like the music!
can you show me how to graph and chart the results when you use 3 types of light, and you have with CO2 and without CO2 and you have to include the seconds
You don’t have to make a heat sink because we are using LED bulbs. But this is basically how you set it up.
I'm planning to conduct a similar experiment in class but I have one question: doesn't the presence of bicarbonate have an effect on the pH? Can this be marginalized?
what the control , independent and dependant ariables ?
Hi, just wondering what the volume of the syringe he used in the experiment? thanks!
