Crash Course Chemistry: Episodes 6-10

Define stoichiometry, relative atomic mass and the mole, and state what one mole of an element equals in grams

Recall Avogadro's number as the count of atoms in a mole of any element, and identify carbon as the base for the atomic mass unit

Explain why the number of atoms of each element stays the same across a reaction, and which molecule to balance first

Take structured notes from a chemistry video, distinguishing a quoted definition from a factual detail such as the year isotopes were discovered

The timestamped set is the one to use when the episode is being played to the whole class: each item carries the minute and second its answer is given, so the video can be paused on the exact line.

The untimestamped set repeats the same questions without those cues, which makes it the version for independent viewing, a retake or an assessment.

Every episode address appears twice — once on the links page near the front and again at the foot of the matching completed guide — so the right video can be found from either end of the packet.

Answers are often the exact words spoken on screen, quoted inside the question ("the science of ____ that go into and come out of any given reaction"), so students should be told to listen for the phrasing rather than paraphrase it.

Guided video note-taking — students complete fifteen or so items per episode while it plays, each anchored to a specific moment in the running time.

Chemistry vocabulary capture — items require the terms themselves to be written in: stoichiometry, relative atomic mass, mole, AMU, redox.

Reading a quoted definition for its missing part — several items reproduce a sentence from the episode with one phrase removed, so the answer has to fit the quotation exactly.

Answering across question formats — the same page mixes gap-fills, TRUE or FALSE judgements, four-option multiple choice and circle-one word choices, so students switch response mode item to item.

Self-checking against a completed copy — the answer section reprints each guide with every response filled in, including numeric answers such as 1912, 1961 and 6.022 x 10 to the 23rd.
