AI Thread Summary
The discussion highlights the effectiveness of using animations to teach chemistry concepts, emphasizing that they can significantly enhance understanding compared to traditional textbook images. Participants suggest that live demonstrations, even humorous ones like using bananas, could engage students better, although there's a light-hearted acknowledgment that such antics might reinforce stereotypes about chemistry professors. The conversation also touches on the value of creative teaching methods, drawing parallels to a memorable film clip of a traffic cop directing traffic in a ballet-like manner, showcasing the potential for engaging presentations in education.

I was wondering why you hadn't just reported the post, until I looked at the thread. :smile: Those are great animations. Anyone who has to teach chemistry should be pointed to that thread...much easier to understand with those than with pictures in a textbook.
 
Or simply demonstrate the modes "live" to your class, holding a banana in each hand. :smile:

:smile: Oh dear! I think most students already think chemistry professors are bananas. That would definitely not help. :biggrin:
 
This also makes me think of a film clip I saw once, showing a traffic cop standing in the middle of an intersection with a baton in each hand, directing traffic as if he were in a ballet.
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
