CHEMISTRY: So tell me again – how do you know if a chemical reaction has occurred? Here’s the lecture on the evidences of a chemical change and the intro to balancing chemical equations. Great to be back to chemistry!
🙂

Are their exceptions to balancing? Will there ever be a formula that works but does not balance correctly?
Does there have to be a color change for a chemical reaction to occur?
Thanks for letting us work explore zone! It was alot of fun!
Thank you for taking some time to helping me with this today!
I had so much fun helping with the explore zone. I really enjoyed seeing everyone’s hard work come together!
Explorer zone was so much fun! I can’t believe the school year is almost over.
i wonder if the little kids still think they are gonna die if they eat snow
Thank you.For I have been learned today.
I never knew balancing chemical equations could be so tricky! I also really enjoyed the explore zone, it was great!
the lab today in the computer lab was sort of challenging but i think it helped me alot
Explorer zone was so cool all the experiments and exhibits were so interesting
The activities in the computer lab were great practice for balancing equations!
Explorer Zone was very fun. I’m glad I got to experience all of the exibits
Is there a certain limit to the number of equations you balance at one time?
Thanks for letting me work explorezone!
the excersizes in the computer lab was very challenging but also very helpful!!
when will the next help session be?
