There is a new file available on the Potions event page with the periodic table.
Some notes from the January 29 coach workshop:
1) The different point distribution does not mean the number of experiments will increase during the exam (usually 2-4 experiments), but rather the weight of the experiment and follow-up questions will be larger.
2) Powders that will be tested in the exam are likely to be powders available in every household (i.e. baking powder, baking soda, flour, salt, sugar, etc.) Students should be able to differentiate between each powder.
3) There are multiple types of colloids including sol, emulation, foam, and aerosol. I do not expect students to name the subclass of colloids (other than emulsions), but be able to identify if I gave an example like smoke or cheese as a colloid. I found this link to be helpful https://chem.libretexts.org/Bookshelves/Physical_and_Theoretical_Chemistry_Textbook_Maps/Supplemental_Modules_(Physical_and_Theoretical_Chemistry)/Physical_Properties_of_Matter/Solutions_and_Mixtures/Colloid
4) Example of clean up instructions. (Specifics have been replaced with ‘XXXX’)
- Continue to wear your gloves and goggles during clean-up.
- Leave all liquids in the rack on your workbench.
- Discard bags containing XXX, XXXX, or XXXX into the garbage.
- Discard all weigh boats, spatulas, transfer pipets, pH strips into the garbage.
- Periodic Tables and pH scales should remain at your workstation.
- Remove your gloves and discard in the garbage.
- Leave goggles at your work station if you did not bring your own.
- Raise your hand when you are finished. Your test will be collected, your workstation will be inspected, and you will be dismissed.
5) The Basic Bohr Model of an element will not be graded on location of electrons, but the number of electrons in the appropriate shells (rings).
