Curated OER
Does 1 + 1 always = 2
What a great way to explore the scientific process! Learners conduct an experiment in which they use sugar and water to illustrate the concept of solutes and solvents. With this hands on approach, they are bound to remember what they...
Curated OER
Marvelous Mixtures
Fifth graders design an experiment in which they separate mixtures. In this mixtures lesson, 5th graders define mixtures, solutions, solutes, and solvents. They watch a video, complete worksheets, and perform an experiment to separate...
Curated OER
Rate of Solution Lab
In this rate of solution worksheet, high schoolers determine how quickly a solute dissolves in a solvent by testing one independent variable such as temperature, particle size or the amount of stirring. Students design their experiments...
Curated OER
Solubility Lab
In this solubility worksheet, students test a variety of polar and non polar substances to determine which ones will dissolve in vegetable oil and which ones will dissolve in water. Students collect data and answer 2 questions about...
Curated OER
Molarity Worksheet
In this molarity worksheet, students fill in unknowns such as mass of solute, moles of solute, volume of solution and molarity of solution in a chart with given solvents. They also calculate the molarity of solutions in other problems.
Curated OER
Water - the (Nearly) Universal Solvent
In this water worksheet, students explore the reasons why water is considered a universal solvent. Students compare different ways to change the dissolving rate of a solute. This worksheet has 11 fill in the blank and 8 matching questions.
Curated OER
Molecular Movement in Water Part 1- Diffusion
Students obseve and compare molecular movement within water at various temperatures and of varying salinity. They discuss the movement of water on a larger scale which can affect the movement and concentrations of microbial populations...
Curated OER
More on Temperature and Solubility
Students discover how temperature effects the solubility of solutes by experimenting with a range of temperatures. They develop skills for observing, inferring, measuring, comparing and contrasting.
Curated OER
How Can Mixtures Be Separated?
In this mixtures worksheet, students brainstorm the problems and possible solutions of how to separate mixtures. This worksheet is a graphic organizer.
Curated OER
Teaching about Conductivity
Students explore conductivity and productivity in aquatic systems.
