Surface Area and Dissolution Rate
This 1-page packet guides 7th graders through concepts of surface area and dissolution rate. It includes definitions, calculation practice, and prompts to explain factors affecting dissolution, supporting the development of scientific vocabulary and explanation skills.
“sub work assignment TEKS*: 7.1D, 7.1F, 7.3B, 7.5B, 7.6E TEKS Specificity Document ELPS: 2.E LO: I am learning about surface area and dissolution rate. Language Objective: I will share my findings of how temperature, surface area, and agitation affect the rate of dissolution using sentence frames and lab partner talk. SC: I can describe and define surface area. I can calculate the surface area of objects. I can describe and define dissolution. I can explain the factors that affect dissolution rate of substances in water.”
Teacher Guide & Tips
- Use as a 45-minute introduction or review of surface area and dissolution.
- Discussion question: How does the surface area of a sugar cube compare to granulated sugar, and how might this affect how quickly it dissolves?
- Scaffold for struggling readers: Provide sentence frames for the explanation section, such as "As surface area increases, dissolution rate ______ because ______."
- Extension for advanced students: Have students research and present on real-world applications of controlling dissolution rates (e.g., in medicine or cooking).
- Estimated time: 45 minutes.
