Figure F.24 - Stoichiometry cannon
- Hook: Popcorn – “What do we know about stoichiometry?” This short activity recounts student memories on what they know about stoichiometry and what it was used for. This is also an area where they can ask questions once more on stoichiometry and how it can be used. The class can also discuss why stoichiometry can be used in gases (i.e. because formulas including gases also use molar ratios and therefore, stoichiometry can be applied to gases as well.
- Action: Students will answer questions based on Dalton’s Law of Partial Pressures using on the board. This provides students with proper practice before moving on to their homework. The first example can be done as a class, the second can be done by a student volunteer and the third will be done individually and the method and answer will be taken up. This follows the gradual release method.
- Debrief: Students will complete their gas laws list and summaries. They will work in groups of 4-5 to create a large list of gas laws accompanied by drawings to help them understand the relationships between variables.
