Elaboration
- Sample opportunities to support student inquiry:
- How do spectral lines relate to the quantum mechanical model?
- How would you measure negative and positive impacts of chemical reactions on human health, society or the environment in your local community?
- How would you safely prepare and collect a gas (e.g., collection of hydrogen from the single displacement reaction of Zn and HCl displacing water from a tube)?
- How could you use solution chemistry analysis techniques to investigate local water or soil samples?
- Demonstrate Avogadro’s hypothesis (e.g., Zn and HCl to produce a mole of H2 gas).
- Use a solubility chart to predict whether ions can be separated from a solution through precipitation and outline an experimental procedure that includes the compound added, precipitate formed, and method of separation.
- How would you estimate the uncertainty in a measurement, and how does using significant figures communicate uncertainty?
