If you are not part of the solution, then you are part of the precipitate. The presentation covers solutions, suspensions, solubility, dissociation, and acid/base reactions. This is the 19th lesson in a series of 26.

Young scientists demonstrate their understanding of cell transport on this comprehensive worksheet. Focusing on cellular structure and the different processes that allow materials to move into, out of, and throughout animal...

There's no need to water down the resource. A tutorial takes learners through the process of creating dilutions for any solution. Specifically, it focuses on serial dilutions with successive factors of 10.

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

Exactly how environmentally friendly is your school? From the air fresheners in the bathrooms to the cleaning solvents used in the classrooms, young conservationists search the school grounds for sources of air pollution in...

From molecules to nanotubes, an engaging unit explores the world of tiny science. Fifteen hands-on experiments and lessons engage young scientists as they learn chemistry. Discussions, worksheets, and data analysis reinforce the concepts...

Understand how temperature, pressure, and the presence of other solutes affect the solubility of solutes in solvents.

[Free Registration/Login Required] While paying attention to the charges, move the salt ions and water molecules around to simulate how salt ions are dissolved in water.

Students identify and control variables to design an experiment to see whether the temperature of a solvent affects the speed at which a solute dissolves.

Students use their own model of a salt crystal and water molecule to show how water dissolves salt. Then, they relate their observations to the structure of salt, water, and alcohol on the molecular level.
