Solubility in Water
Students will classify matter based on physical properties, including mass, magnetism, physical state (solid, liquid, and gas), relative density (sinking and floating), solubility in water, and the ability to conduct or insulate thermal energy or electric energy.
The student knows that (1) matter has measurable physical properties and (2) those properties determine how matter is classified, changed and used.
What are Mixtures and Solutions? Virtual Chembook from Elmhurst College (website) - Easy-to-read chart that defines/differentiates between homogenous and heterogeneous mixtures, solutions and colloids.
Solutions and Mixtures: Chem4Kids (website) - Basic information about solutions and mixtures, accompanied by clear illustrations that promote understanding of basic chemistry.
What Dissolves in Water: BioEd Online (website) - Students investigate whether several common substances are soluble in water.
- Supporting Lessons
- Assessment Ideas
- Literature Connections
- Additional Resources
How Can We Find Out What Is in Water? BioEd Online (website) - Students use simple paper chromatography to investigate a mystery liquid, comprised of different substances dissolved in water.
Elaboration Lessons and Extensions
State Your Solution: American Chemistry Society (website) - Investigation that helps students understand what it means for a liquid or a gas to dissolve in a liquid.
Can Gases Dissolve in Water?: American Chemical Society (website) - Students will design experiment to measure gas in club soda.
- Have students create a chart of sample mixtures and non-mixtures.
- As a performance assessment, create several different mixtures and challenge students to separate (or come up with plans to separate) the mixtures into their separate components.
