Factors That Affect Rate of Dissolving and Solubility
Lesson Plan Title: Factors that Affect Rate of Dissolving and Solubility
Overview, Expectations and Rationale
1. Big Ideas: • Properties of solutions can be described qualitatively and quantitatively, and can be predicted
2. Ministry Expectations:
Scientific Investigation Skills and Career Exploration
A1.1 - formulate relevant scientific questions about observed relationships, ideas, problems, or issues, make informed predictions, and/or formulate educated hypotheses to focus inquiries or research
A1.4 - apply knowledge and understanding of safe laboratory practices and procedures when planning investigations by correctly interpreting Workplace Hazardous Materials Information System (WHMIS) symbols; by using appropriate techniques for handling and storing laboratory equipment and materials and disposing of laboratory materials; and by using appropriate personal protection (e.g., wearing safety goggles)
A1.5 - conduct inquiries, controlling relevant variables, adapting or extending procedures as required, and using appropriate materials and equipment safely, accurately, and effectively, to collect observations and data
A1.8 - synthesize, analyse, interpret, and evaluate qualitative and quantitative data; solve problems involving quantitative data; determine whether the evidence supports or refutes the initial prediction or hypothesis and whether it is consistent with scientific theory; identify sources of bias and error; and suggest improvements to the inquiry to reduce the likelihood of error
Specific Expectations
E2.1- use appropriate terminology related to aqueous solutions and solubility, including, but not limited to: solubility, precipitate, ionization, dissociation, dilute, solute, and solvent [C]
E3.3 - explain the effects of changes in temperature and pressure on the solubility of solids, liquids, and gases (e.g., explain how a change in temperature or atmospheric pressure affects the solubility of oxygen in lake water)
