The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...

Young chemists grow ionic crystals, metallic crystals, and supersaturated crystals in three different lab experiments. Observing these under a microscope allows pupils to compare the various structures. 

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...

How do chemists use solubility data? Chemistry scholars learn the usefulness of solubility curves and how they are generated. The seventh part in a series of 14 discusses the solubility rules, plotting solubility data, and how pupils can...

Candy rocks! A sweet lesson offers a different take on the rock candy experiment. Groups use a supersaturated sugar solution to create rock candy. Pupils then add other ingredients to the solution to test their effect on the...

The best part of learning about equilibrium is that nothing changes. Young chemists observe four demonstrations during this instructional activity: equilibrium in a saturated solution, equilibrium with an acid-base indicator, equilibrium...

In this solubility worksheet, students identify substances as either ionic or molecular, define saturated solution and solubility, and calculate concentration of solutions. This worksheet has 7 short answer, 5 fill in the blank, and 27...

In this solutions worksheet, students determine concentrations of reactants at equilibrium. Students describe the effects of adding reactants have on the solubility of a compound. This worksheet has 5 problems to solve.

In this solutions worksheet, students determine at what pH aspartic acid would be protonated. Students create buffer solutions with a certain pH and determine the solubility in certain solutions. This worksheet has 8 problems to solve.

In this solutions activity, high schoolers determine how the amount of solute in a given amount of solvent effects the concentration of the solution. Students calculate the molarity of solutions. This activity has 7 fill in the blank, 3...

In this aqueous solutions worksheet, students will explore the characteristics of solutions, including the ability of different compounds to dissolve in the solutions. This worksheet has 10 true or false statements and 8 short answer...
