I failed chemistry in high school and was given a passing grade to not retake it and graduate l. I am happy to have at least gotten two of these right lol
I'm proud of you! These were some tough questions! Also, if you ever want to start from the beginning, I have a Chemistry playlist that breaks stuff down super easy! (: Thanks for watching!
Plants are really cool because they use both! Both capillary action and osmosis are used to bring in water and nutrients! This definitely gives me an idea to make a future video about the differences! Thanks for watching!
@@doodlehomework Thank you. I have to admit that my motivation wasn't science based. Every time we go out into the woods, I try to teach them another aspect of survival and bushcraft. I did want them to see capillary action but also made clear that this does nothing to remove pathogens
Wow! I did this in 1st grade, almost 50 years ago, and have been trying to find out what the process was for about the past 20 years. Hours of doom scrolling finally paid off!
My friends and I would challenge each other back in high school. By putting salt on the back of your hand/wrist, then place an ice cube on the salt. The salt starts "eating" at your skin, causing a burning feeling. I still have a scar on the back of my wrist for doing it for 30 mins straight.
@@doodlehomework oh wow that's great! What kind of hoya tho? My guess is Lacunosa 'Splash' I've been trying to grow hoyas alongside orchids for quite a while now, and I've never gotten it to bloom, grrrr I'm never buying this plant again (my hoya is an Australis)
Mine was a clipping from a family member, so I'm not sure what kind of hoya it is. I know that the original plant the clipping came from is over 100 years old though! :D I'm sending positive vibes for your hoya to bloom!
@@Leopard_211tl;Dr against UV light, yes, to protect from sunburn. If you have a dedicated UV-c lamp it will basically only emitt visible, blue-ish light for you to know that it's turned on. The majority is high energetic UV light with a higher power-density than the sun light reaching you. Baaaasically the same reason you weld in long-sleeves and with a shield/helmet. It's not (only) against the heat but so you don't get the UV dosage of a summer day within 2 minutes.
@@Leopard_211 there is no immediate danger, apart from light burns, no pun intended. Just the "usual" cancer risks ;) I learned the hard way... Had suitable glasses (no simple sunglasses) and no gloves. Very unpleasant burn on the back of my hands after setting up a test-stand with a UV-"flashlight". Your welcome :D
Thanks for the question! Yes, that's correct and is actually another cool way that the atmosphere changes our perception on color! On Earth, the sun appears more yellow because of our atmosphere, but in space it is white!
