If the wotsit fell and was still lit on fire for a few seconds wouldn’t that affect the results bc it had more energy than measured… just curious great vid
Thanks so much for this video I remember watching it in class but forgetting about this topic but had to re watch it again and all I can say it’s been a big help, thanks 🙏🏾 💙
Oh, is this the laboratory in your school? That's nice! Good to see you back for another IGCSE science video. What if you consider on a Physics practical?
Someone should be holding the thermometer so that it is not touching the bottom of the test tube. Your results for this experiment will not be accurate because the thermometer is measuring the temperature change of the glass, not the water.
Nice experiment, but... You can do the same with a piece of wood, and yet, humans chewing on a piece of wood will not get the same percentage of energy from the wood as they do from the 'food'. How can we measure how much energy a human would actually get from a certain amount of food?
You’d probably choose to use a small bit of popadom, but if you were determined to use something bigger then yes, you would. Maybe using forceps instead of a mounted needle though

this is my science homework
Same bro
Same
Same shit
Same lmao
how d you have the equipment for this at home lmao??!!
A level biology, and this is peak science right here.
Here i am wondering why there burning a perfectly good wotsits
Seems fair. The wotsit was sacrificed for the greater good.
Thank you so much for that breakdown! Amazing keep up the content!
Anyone else here in lockdown?
me
Doing my science homework LOL.
me
Feels like forever ago
Q: Why is it important to calculate the energy released in J/g?
They literally said that it was optional
I’m in class rn and my teacher told me the watch this
Hope you enjoyed it!
same
@@SciencewithHazel I Did not Enjoy it because it was not interesting
Same
@@shafeymushtaqch1493 bit rude they took time out of their day to make this

I winder if it would be worth lifting the heatproof mat towards the water to continue
Thanks for a great video, a nice resource for my KS3 classes.
Thank you! Happy to hear that it’s been helpful
I am so glad u are starting practicals please do more as i am doing all my sciences practicals in my AS level thank you. :)
Hoestly...this was so so so helpful! thank you!
i think u meant honestly
I remember doing this in year 6
Awesome moments lol
Rn in sciene class lol
@Magne Thyregod Guess what... Nobody asked you to live :)
@Magne Thyregod don’t be toxic ur only toxic bc parents don’t love u
Great practical. For accuracy sake, can the energy result be compared to the numbers listed on the package?
This is my science Homeschooling work :D
This was really helpful . What if the food sample had some moisture in it?
Yess.. how about it? I wanna know..
Thx it made my understanding of this topic and I remomised the formula easly thx again
Can anyone tell me two improvements that should be done to the investigation? Its for homework
I think you’ll find it’s perfect
But really: repeat the experiment, test more foods
Science with Hazel wow thank you so much!!! And for the quick response 🙏🏻👍🏻
set up a barrier around the apparatus to reduce the heat loss
Same this is my science homework
whos got to watch this during a online lesson
Thanks so much for this video I remember watching it in class but forgetting about this topic but had to re watch it again and all I can say it’s been a big help, thanks 🙏🏾 💙
Loving your merch and vids
anyone else having to watch this for school?
Hope it’s helpful!
just a side comment - you left the bunsen burner on after the experiment, and on the blue flame, not the safety flame. Surely you turn it off?
great help, thank you x

@@kevo3484 LMAO fr
Does this technique work with fruits as well ? If I want to know the energy produced by fruit, can I use this technique?
Probably too much water.
Homework 👌
anyone here cos of physics live lesson
science lesson got me to watch this
Haven’t seen a better video yet
You should really hold the boiling tube at an angle to prevent the flame burning any of the clamp.
This is my science hw 🤠🤠
:O this experiment is cool but it is sometimes risky as ppl might not hold it properly and burn their hand
thanks Emilia and Hazel 😁
I'm here for the Mrs.Jones pnd for chemistry 🤦♀️
I got sent here by my teacher
thank you that was very helpfull
I really appreciate your explanation.
We all do, Infinite. We all do
great video
A nice, relaxing voice.
Helpful
Thanks!
Someone should be holding the thermometer so that it is not touching the bottom of the test tube. Your results for this experiment will not be accurate because the thermometer is measuring the temperature change of the glass, not the water.
And this is my Biology homework
👍
Can someone tell me the different variables please.
Independent - type of food. Dependent - temperature increase. Control - mass of food, surface area of food etc
@@SciencewithHazel Waow u gave her the answers to a criteria B assessment. But I guess thats the purpose of you channnel so, oh well..
@DextrousSteam24 Because I go to ur school and IK ur real name, i wont say doe cuz u kno, secrecy.
@DextrousSteam24 who am I may I know also I'm glad you know who I am 😂😝
@DextrousSteam24 Christian kiddo I know who you are too. Hhahahahahahahahahahah😂
Please make more video like that
im hungry
Nice experiment, but... You can do the same with a piece of wood, and yet, humans chewing on a piece of wood will not get the same percentage of energy from the wood as they do from the 'food'. How can we measure how much energy a human would actually get from a certain amount of food?
the reason it doesn't work with wood is that humans can't digest it. if humans could digest wood, they would get whatever energy the wood contained.
@@user-uv5wv3tp7h Of course. But with any food product, how can you know how much % of the energy content is actually absorbed by the body?
@@koenvandemoortel2206 got to go to uni for that, then do a phd, then spend 10 years researching
RIP wotsit
bunsen burner is on firee!!!!!!!!!!
WOTSITS ARE THE BEST CRISP EVER!
Pov: every1 here is from science class
3 control variables?
The fact we did it without any safety yesterday just makes me wanna cry lmao
😥😥My class couldn't do the experiment because my school went to home learning.
yep
Ooooh loving this change of scenery (>~< )
the last time i did this in school i had to stop my freind from burning pringles to 100 degrees causing smoke in the room
can anyone tell me how we can use this experiment but with FLOUR?
Wassup lads
lassies*
who else is here becuase this is their science work
What is “c”?
Specific heat capacity
@@SciencewithHazel please help me
With example-
Because the result c= 4.2 of your video, got more out of it than it helped me
4.2 J/g/C is the specific heat capacity of water. You will always be given that value in an exam question if it comes up.
@@SciencewithHazel ok now I understanding- this is a standard value
Correct?
So say if you did a bigger food , like a popadom would you do it the same way?
You’d probably choose to use a small bit of popadom, but if you were determined to use something bigger then yes, you would. Maybe using forceps instead of a mounted needle though
Ok thank you
what would you title this experiment tho?
How to determine the energy content of foods
@@SciencewithHazel Thank you so much!! i just submitted the essay draft but I will include this in the full copy. THANK YOU!!!!
how did you find the specific heat capacity ?
Reuven bro
HeLLoeU
Joseph Sebastian brooooo
Ready for biology test
@@josephsebastian6567 cmon bhai this is where biology took us too
1:45 no shit ur literally holding a fire under it
that is EXACTLY what i said i was like well no shut sherlock there is fire under it lmao
What is the object called they pour the 20cm3 of water from into the boiling tube
im pretty sure its a graduated cylinder
Hello Classmates!
i could of ate that wotsit ):(
School brought me here
Omg Harrison is cracked at fortnite
Can u put a mic when u speak cuz it is hard to hear
Can thermometer touch bottom of tube?
And one more question, why you don’t off the fire?
ma teacher sent me hear should i sub?
HUH the poor wotssit.
You should definitely sub
im here for mongfeild
Who’s here in Covid doing home learning 🤣
Hi it’s me Sam
Lol year 8 kids from Australia are here
Ahh tasty flames
Dam bro am in 7th grade rn the people who commented this are now in 11th grade time flies
i wndered why they set the watsit alite and it looked like they were trying to brake the glass of how black it was 🤣
POV-You are watching this for your science homework
I don't get why you would multiply by 4.2 please could anyone explain 😭😭
It’s the specific heat capacity (c) of water in kJ
bro why am I doing this to myself
My science teacher told me to watch this -
Your science teacher has great taste
@@SciencewithHazel :)
Hello 8Y1
my science teacher sent me here
👍 I like your science teacher
Same!!
Rip wotsit
biology homework anyone?
Haha
my science teacher gave me this-
90w
ngl the girl on the right doesn't seem enthusiastic at all
Science
no
Bruh hello work
who ate the rest of the pack of wotsits
im here purely because of school
A likely story...
School
people here from ags like this comment
Bruh
who else goes to QE Boys lol
🙌🙌🙌
anyone else utterly confused
