Exploring Solutions F Rate of dissolution

C.10.F Investigate factors that influence solubilities and rates of dissolution such as temperature, agitation, and surface area

1. Initiating Progress Students define temperature, agitation, and surface area. DIY: Use dictionary to define temperature, agitation, and surface area. (No Assess for this level).

2. Approaching Expectation Students can identify factors that influence solubilities and rates of dissolution such as temperature, agitation, and surface area. DIY Read Ch. 9 Section 2 p. 275 (ebook p. 287) Dissolving Rate. Assess: Level 2 Progress Check

3. Meeting Expectation Investigate factors that influence solubilities and rates of dissolution such as temperature, agitation, and surface area. DIY Design a lab and carry it out after teacher approval, per "Inquiry Lab Planning Guide: Rate of Dissolving." Assess: Turn in Lab Report (as detailed on planning guide). Make sure you explain your reasoning explicitly, as described in this 7-min. video.

4. Exceeding Expectation Students analyze factors that influence solubilities and rates of dissolution such as temperature, agitation, and surface area as well as their application to aquatic environnments. DIY: Read p. 276 (ebook p.288) Solubility of Gases in Liquids. Assess: Warm Up to Science #76 Progress Check
