Phase Changes 

@Madison Dunn Ahahahahaha

Lmao I can’t unsee this

Lol😂🤣

damn i want my old eyes back ajajajaja

omg- I see it

Tyler DeWitt what are the phases

yes so good my teacher assigns it so she doesnt have to teach

lol mine too

@MANUEL GOMEZ same !!

OMG same!

Same

Mine too lmao

Stages of matter is physics not chemistry.

6 years later did u pass?

Five years later I’m in your spot .

Mr. Chesbro! What a surprise! I hope things are going well at good old MGRHS.

I hope they are too! I'm teaching in NJ. Or, should I say, "The Peoples' Republic of New Jersey."

Hey mr.Chesbro I’m your student

I’m a student too lol

I'm a random person reading this comment

why does dominos customer support need chemistry help what are yall doing in that kitchen my guy 💀

You're absolutely right. "Thermal Energy" is the correct term. But these videos are designed for the most basic learners, such as the middle schoolers that I teach. I made a conscious choice not to use "Thermal Energy," because I've found that jargon is one of the fastest ways to make kids hate science. "Heat" is something that students have real-world, previous experience with, so they can build mental models with the concept of heat. "Thermal energy" doesn't mean anything to a 12 year-old, so they can't immediately connect the concept to something they already know. You and I may disagree on this issue, and I respect your opinion, but for me, I'll always choose the quickly understandable, relatable explanation above the more obscure, 100% technically accurate one. At least when I'm teaching young learners. If you're interested, I did a TED Talk about this concept: you can find it on the TED.com website under my name.

Tyler DeWitt Colleen Windell even my chemistry professor at my university uses "heat" instead of "thermal energy"

+Colleen Windell Check out Tyler's TED Talk - he discusses his methods for teaching science and the choices he makes with language to best facilitate his student's learning.

Sarah Thomason agree Sarah

Sorry, I am not trolling anyone here, because I am just taking Chem II right now, but I am thankful for +Tyler DeWitt style of teaching. These videos are what help me grasp the concepts and help me pass my chem exams, instead of the actual instructor that is teaching the lesson and writing the exam. I have to say this is my favorite part, "If you're interested, I did a TED Talk about this concept: you can find it on the TED.com website under my name." "Under my name" LOL But in all honesty I see your point +Colleen Windell, I am assuming you don't want us to water down the subject, but instead raise to the occasion and understand it on a very technical level, but not all of us are trying to become Chem majors. P.S. I love the PhET simulation.

Monisha Tejani c9 lul

+devashish joshi yup you are right

Same sucks ass

i can try lol but im probably too late. Sublimation is when solid goes to vapor, and deposition is when vapor goes to solid. They are opposites of each other.

dark light deposition

its like a comparison between something confusing and something people understand

Quds7 noice copy paste skills kiddo

hello

ItsJay I know. Its awesome.

ayo wtf 💀
