Presentation Transcript

  1. Solutions Factors affecting solubility A curricular unit developed by Lisa Allen and Faith Hughes, NSF Summer Institute, Boston University, 2002

  2. Target Population • Average level high school introductory chemistry • Grade 9 Physical Science • With modification, middle school physical science

  3. Objectives: Wet Labs • Students will generate quantified data to determine the effect of stirring on solution rate • Students will generate quantified data to determine the effect of increased solute surface area on solution rate

  4. Discovery Learning: Stirring Lab Students design and implement a wet lab evaluating the effect of stirring on solution rates Lab design, control of variables and measurement are the focus Modern Chemistry, Holt, Rinehart, & Winston, 2002

  5. Objectives: Simulab • Students will illustrate and describe the effects of changing surface area on solubility • Students will observe the effects of changing temperature on solubility • Students will generate a graph, and write a paragraph explaining the effect of increasing temperature on solubility

  6. Virtual Molecular Dynamic Lab • Students work with 2 simulations to observe the dissolving process on a molecular level • Students collect data, utilize technology to create a visual description of the dissolving process • Students explore the effects of temperature and surface area on dissolving

  7. Virtual Molecular Dynamics VMDL, Center for Polymer Studies, Boston University

  8. Virtual Molecular Dynamics: a tool for teaching and evaluation • Students capture images, write captions to illustrate understanding • Students view common phenomena on a molecular level • Visual learners understand concepts, apply vocabulary later VMDL, Center for Polymer Studies, Boston University

  9. Objectives: Demonstrations • Students will use appropriate vocabulary to describe common phenomena on a molecular level • Students will relate common phenomena to a computer simulation

  10. Demonstration of Solubility As a Function of Temperature Modern Chemistry, Holt, Rinehart, & Winston, 2002

  11. The Solution? • Use wet labs, computer simulations and demonstrations to provide all learners opportunities to experience success • Vary methods of instructions as well as evaluation Modern Chemistry, Holt, Rinehart, & Winston, 2002
