Density and Miscibility
The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The activity covers the topics related to mixing and...
Curated OER
The Nature Of Dissolving Processes
Students examine the rule of "like dissolves like." They define and describe solutions and solubility models on molecular liquids, ionic solids, and molecular solids.
Curated OER
Ocean in a Bottle
Young scholars investigate pollution in water. In this pollution lesson, students participate in an experiment to simulate water pollution. Young scholars observe how the water reacts to the "pollution."
Curated OER
Ions in the Environment
Students explain the importance of the five main biogeochemical cycles. In this chemistry lesson, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.
Curated OER
A Solution for Precipitation
Students predict the product of chemical reaction using the solubility rules. In this chemistry lesson, students balance ionic equation. They perform a lab to check if their predicted products are correct.
Curated OER
A Solution for Moles
Students calculate the concentration of different solutions. For this chemistry lesson, students explain what a solution is. They explain ways to change the concentration of a solution.
Curated OER
Ocean in a Bottle
Learners create an enclosed ocean in a bottle and add different pollutants to explore the effects of pollution on the environment.
