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...

Beer's Law can be used to measure the concentration of certain compounds in samples of food. In the concentration simulation, particpants change and measure the concentration of different solutions by manipulating various types of...

In this water and solvent activity, students answer 20 questions about solutes, solvents, polarity in molecules, and the characteristics of water as a solvent. Students answer 3 questions about the lab they completed using temperature to...

In this mixtures activity, students experiment with different amounts of solutes and solvents to make solutions. They observe color changes and look for chemical and physical changes in the test tubes. Students answer 5 questions and...

In this solutions worksheet, students soak a pipe cleaner in hot water and a supersaturated solution of 20 Mule Team Borax. Students leave their pipe cleaner in the solution for 30 minutes and then observe. They put it back in over night...

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...

In this solvents pre-lab worksheet, students describe the difference between a polar and non-polar solvent and also the dangers associated with hexanes and iodine. This worksheet has 12 short answer questions.

Encourage your classes to be laundry helpers! Learners explore the chemistry of stain removal with a lab investigation. By identifying the components of the stain, they identify the most effective solute for its removal.

In this solutions instructional activity, students review how molarity is calculated and how to prepare a dilute solution. This instructional activity has 5 problems to solve.

In this biology worksheet, students determine how many solvent and solute molecules there are in the red blood cell and the IV fluid. Then they determine whether the IV fluid is hypertonic, hypotonic, or isotonic to the red blood cell.

Micelles consist of an aggregate of molecules in a colloidal solution. The simulation presents two different ways the molecules assemble into micelles based on the polarity of the solution in which they are placed. Scholars can set the...

Chemistry explorers prepare a crystalline derivative and find its melting point. Once they discover the melting point, they can identify whether the substance is pure or an aldehyde or ketone. This outstanding laboratory activity helps...

Many scientists attempted alchemy for hundreds of years before a full understanding of metals became clear. Scholars take a penny and, through two different chemical reactions, make it appear to turn into silver and later gold. They...

Explore what happens when one substance dissolves into another. Run the simulations and see if you can predict the results.

Learn how molarity and molality differ. The molality of a solution is equal to the moles of solute divided by the mass of solvent in kilograms, while the molarity of a solution is equal to the moles of solute divided by the volume of...
