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

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

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

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

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

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

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

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

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