This is the first time trying to study potions and poisons . As there no much material available in SO site for this topic, can anyone please help how to prepare for this event ? Where to get study materials for this topics?
Thanks

Well, the event goes over multiple categories, with different ways to prepare for each:

The Potions and Poisons wiki page over most of the general parts for the event. I would very highly recommend just starting on reading up on the Wikipedia page for the common household toxins and take notes on their chemical equations and precautions to take while using them (never mix ammonia and bleach !!)

If you get a partner for the event, it's also possible to split up the toxic plants vs toxic substances, so one person does each, Quite honestly, I'm not too good with toxic plants, but [user]Person[/user] did a pretty good job explaining them on the wiki page.


Thanks man, this is my first year too and I was confused.

For the chemistry side, I'd say it's important to be very quick with balancing chemical equations and recognizing chemical equations, but those should come with practice. It is also important to know basic terminology to classify substances (homogeneous, heterogeneous, solution, mixture, compound, etc) Even though they're simple, they only have slight differences, and it is extremely easy to confuse them (I sure know I do...).
Pro tip: Quizlet has plenty of these definitions to help you study!! (https://quizlet.com/108897808/physical- ... ash-cards/)
Practicing balancing simple equations such as the equation for photosynthesis can prepare, and running a google search for the topic should give plenty of worksheets.

Finally, for the labs (listed in the manual), ask your coaches/science teachers if they can help set up or provide materials to perform them. We set up some labs in school for Food Science for the past two years and ran them, and they went quite smoothly. It's really important to make sure the process for all of the labs, so things don't get messy on tournament day.

Hopefully this helped, and if you want to practice here on Scioly.org, the Question Marathons page is always open for business!
