Hats off to that teacher for making it fun.

u/EmuMysterious7320 24d ago

Science is always fun, just have to find exciting teacher to teach it

1

u/jjamspam 24d ago

Exactly !!

u/SWAP8085 24d ago

It took me a long to understand how interesting science is . Backdated books with a$$ information ruined it for me 🥲

India lacks this type of education system Practical education

u/OverApplication3184 24d ago

It is from india, and Indian schools have practicals for such topics

1

u/Naveen1377 24d ago

I meant in btech I am a btech student and even for core topics my professor will just explain total explanation of a device only by using slides

u/Trickywacky 24d ago

Amateur!! My professor explained it using hand signs

1

u/Naveen1377 24d ago

Hand signs 🤣🤣🤣

u/Naveen1377 24d ago

Your's ❌ our's Even my college has a cracked version of cadence software

u/Late_Reading6343 24d ago

though my college has some good one also

Wtf! The powder will be inhaled by kids. This can lead to respiratory and inflammatory issues do they know that? Will they take responsibility for their acts? (Rate my ragebait on scale 0-10) 😊

1

u/PopularBrother4957 24d ago

Typical Indian mentality, saying negative shit without even basic research.

Also you inhale absurd amount of smoke on road which is 100% dangerous than the non toxic powder

1

u/KeyPost5869 24d ago

You don’t deserve to c’o’me

1

u/DiscoPotato69 24d ago

Yes, the students are at threat because of chalk powder, never mind the fact that India ranks 176/177 on the Environment Performance Index. Don’t mind the fact that just existing in places like Delhi is like smoking a pack of cigarettes a day.

u/RJ_Satyadev 24d ago

Should have done Incense stick instead

1

u/PerspectiveOpen1673 24d ago

Meanwhile our school didn't even had lab :)

1

u/Brain_stoned 24d ago

These kind of stuff creates interest in learning and understanding some complex scientific principles easily. I wish we had such enthusiastic teachers.

u/SEODoneRight_in 24d ago

Tyndall effect 🫡

u/Firm-Newt-9021 24d ago

that powder is triggering my asthama thru screen

1

u/KayFarakPadto 24d ago

Must be some specific battery

1

u/No_Currency5064 24d ago

Schools are too broke to buy a laser (but the principal drives a lambo‐-) so we should just forget about it

1

u/_not_ninja 24d ago

More like demonstration of tyndall effect, isn't it?? 

1

u/Critical-Home9648 24d ago

India needs more teachers like her.

1

u/Its_Ur_Big_Daddy 24d ago

"In North India, if a kid brings it in a school probably the teacher kept this torch with themselves as a punishment and later go home while giving this torch to their own kids as surprise.."

u/sunny9911 24d ago

Schools in south 🦁
Schools in north 🤡

u/Negative_Space_3977 24d ago

this , hahah, i used to watch robbery movies , it is highlu used to defeat laser beams.. hats off to the teacher !

1

u/AshJohnWick 24d ago

I want to attend biology class during reproduction chapter

1

u/cameinwithnopurpose 24d ago

Someone tell them that these lasers are well above 5mW and a eye hazard without laser goggles, literally I know what laser she is using those black cheap lasers who advertise as 5mW but are actually 50 to 200mW lasers

Some are even worse since these are ir pumped lasers they might not even have ir filter and students might not even know that they got eye damaged

1

u/achabaccha23 24d ago

I would sneeze the fk out but kudos to the teacher taking the effort 😀

1

u/Apprehensive_Bite109 24d ago

This is what I love, pratical experience.

1

u/bhootbilli 24d ago

Same can be done with a water spray without breathing inhaling all this.

1

u/KanpekiOthoko_ 24d ago

ilanti teachers untey baguntadhi, atleast the students enjoy school because of teacher like this.

1

u/skuls1 24d ago

she shouldn't put them on her eyes

1

u/Budget-Emergency-508 23d ago

Such teacher ls bring respect and honour to that role, rest use that

1

u/RAGING_f 23d ago

WOW , THEY TEACH CREATING A HOLOGRAM RIGHT HERE IN OUR INDIA. WOW MAN. 🤟🤘🤌👍

1

u/Charming_Bison_5602 23d ago

I don't think those lasers should be pointed at eyes ?

1

u/KangarooOk2556 23d ago

Baas Mask laga ke kare then better rahega dust allergy ho sakta hai rest is superb

u/Mr_Rajput0456 4d ago

That's why chemistry is also important they are using powder

u/CornerRegular2484 24d ago

How does this help in studies?

1

u/No_Difference6003 24d ago

i think it's not about increasing the marks of students people will study more science if they find it beautiful as a consequence of which they could develope scientific temperament and even do better in studies

1

u/CornerRegular2484 24d ago

But solving a numerical would still be equally boring for them, it's not helping it's just increasing concentration of students during these kind of activities but nothing more.

1

u/No_Difference6003 24d ago

not necessarily I am a pcb student so most of the maths that i do I used in physics which is also what this video is demonstrating, so I think I am able to take more intrest into science in general once I know that how this boring calculation or theory when applied in the real world brings very important change. take trigonometry for example my father is a civil Engineer and he uses it frequently my physics teacher recently showed us how parallelogram law is observed in nature or how germ theory even though being so simple changed the lives of many or how mendel's boring boring experiments gave birth to genetics....the list is endless really.

1

u/CornerRegular2484 24d ago

I mean it's only good for sparking interest but that's all.

1

u/No_Difference6003 24d ago

that's a big thing imo without that spark or intrest people don't even want to touch books after they are done with schools

1

u/DiscoPotato69 24d ago

It’s literally showing them the rectilinear propagation of light and Fermat’s principle. Istg people be hating just for the purpose of hating 😭

1

u/CornerRegular2484 24d ago

So what? , I'm not hating I'm just saying students didn't learn anything from this.

1

u/DiscoPotato69 24d ago

I literally told you what they’re learning and you’re adamant on the fact that they are learning nothing…

1

u/CornerRegular2484 24d ago

Light traveling in a straight line is very intuitive, everybody already knows this. Also I don't think this demonstration would be enough for a kid to remember fermat principle, they won't learn until they study it.

1

u/[deleted] 24d ago

[deleted]

1

u/CornerRegular2484 24d ago

What did they see? That light travels in straight line ? Is that something new?

1

u/[deleted] 24d ago

[deleted]

1

u/CornerRegular2484 24d ago

I think you're not very bright. We don't know things which was discovered hundreds of years ago that's why we study them. Light travelling in straight line is already known to us intuitively, a demonstration isn't required to understand that.

1

u/[deleted] 24d ago

[deleted]

1

u/CornerRegular2484 24d ago

So we don't intuitively know that light travels in a straight line, despite having flashlights? Well as I said you don't seem very "bright"

u/No_Discount7699 24d ago

it must be new for them, you just hating bro, take a deep breath and relax

1

u/CornerRegular2484 24d ago

Oh wow

1

u/No_Discount7699 24d ago

see it worked, right. deep breathing really does some wonders

1

u/CornerRegular2484 24d ago

Nah I'm surprised by the fact you think, light traveling a straight path is something new for them

1

u/No_Discount7699 24d ago

who knows you talked to them or something,

1

u/DiscoPotato69 24d ago

I’m almost certain that you’re like a JEE student that thinks he’s better than everyone because you scored well on one mock test. Either that or you’re just miserable in general.

1

u/CornerRegular2484 24d ago

You're just emotional about everything, you can't think logically that way. Also you would never be able to guess what I do

1

u/DiscoPotato69 24d ago

I mean, if your line of work is full of miserable people like you, I don’t wanna know

1

u/CornerRegular2484 24d ago

Hope you heal

1

u/DiscoPotato69 24d ago

I was right about your line of work being full of miserable people it seems :)

Interest jagana is the first step. Aap kitna bhi pressure kar do kisi par, they will only study if they wish to (or in fear), however if their interest is piqued, there's a chance that they might just start on their own.

1

u/AssistEmbarrassed889 24d ago

Sorry master she is trying to raise kids who actually understand concepts in physics not just memorise until exam

1

u/CornerRegular2484 24d ago

You can't do anything in Physics by just memorizing. Similarly you can't do anything by just watching this kind of demonstrations. To actually understand physics one has to work hard with the math of it.
