Screaming Gummy Bears Demo!
This demo consists of two reactions:
The first is the decomposition of sodium chlorate as it is melted with the blowtorch.
2NaClO3 (s) --> 2NaCl(s) + 3O2 (g)
The second is the combustion of the sucrose in the gummy bears upon coming in contact with the newly formed gas from the first reaction.
C12H12O11 (s) + 12O2 (g) --> 12CO2 (g) + 11H2O (l)
The result is a VERY exothermic reaction! This also gives us flashbacks to emission spectra since as we are working with sodium chlorate, it releases a bright orange light. Another version of this reaction works with potassium chlorate, which forms a white pink light!

Hess's Law Lab
Hess's Law Lab
This lab was a last minute replacement as the original intention was to calculate the calories in marshmallows. However, our alarm kept having issues so we decided against it.
This lab was an easy last minute plan. Being in Korea we could not find Styrofoam cups last minute and actually ended up using paper cups with lids and wrapping the entire thing in bubble wrap. Surprisingly, most groups still had a low percent error so this was quite effective. Will most likely change this lab next year though.
7.7 - Unit 7 Review
7.7 - Unit 7 Review
As of this year, HL and SL are combined so this PPT doesn't contain HL only contents and I had done it during a separate class but very informally. If I ever get a free minute I will adjust this PPT, but most likely it won't get fixed until next year.

"How can I study for the quiz?"
PPTs
HW Questions (Optional ones you didn't do, go back to them! They are past paper questions, straight from previous years!)
Youtube - MSJChem and Richard Thornley have great videos directly IB based
Quizlets - Already made, can import into Anki. Or can star specifically the ones you are struggling with, and learn only starred terms.
Revision Village
Textbook questions & readings - There are books from Hodder, Oxford, and Pearson (let me know if you need links). They each have their strengths and weaknesses. I reference all 3 when I am making my lessons.
Throughout the year you will cycle through these options and experiment with what works for you.
