Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...

Amateur chemists define and describe properties of solutions, compare solubilities, explain how solutes affect freezing and boiling points, describe acid and base properties, and more! This educational PowerPoint provides information and...

Scientists require specific chemical solutions for their experiments. In the seventh and final installment in a series that integrates chemistry and algebra II, scholars learn to set up a system of equations to solve the volume of a...

Here's proof that small-scale labs lead to big-time learning. Introduce acid-base interactions to middle school scientists through a microscale chemistry lab. Pupils combine a variety of solutions and use indicators to obtain approximate...

Titration experiments don't have to give your high schoolers a stomachache. Study the ways to titrate an acide with a base in an engaging science experiment, which involves creating solutions and performing titrations. Pupils...

This is an effective simulation of how communicable diseases such as AIDS can be spread throughout a population. Classmates exchange samples from their individual cups of liquid: one of them containing a dilute NaOH solution, and the...

Systematically diluting a full-strength sample of food coloring is meant to help earth scientists understand concentration in parts per million. While they will enjoy the lab exercise, it might be a challenge to help them relate it to...

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.

Model and explore osmosis using squash and potatoes. Young scientists expose chunks of potatoes to different concentrations of a squash solution. They compare the weights of the chunks before and after exposure to the solution and use...

Learners demonstrate the meaning of dilution and concentration and how pollution can affect the water that you drink. They perform an experiment to calculate the final concentration and dilution factor of solutions. They record the color...

Test six various reagents for their ability to conduct electricity. Cooperating chemists research whether each is ionic or covalent and discover the relationship between bonding and conductivity. This laboratory exercise would be an...

In this solutions worksheet, students answer 18 questions about solutions, saturation of solutions, solvents and solubility.

There's no diluted learning here! Young chemists conduct a virtual lab exploration to practice their stoichiometry skills. By manipulating simulated solutions, they create a solution of a specific glucose molarity.

Where did the pH scale come from? Take a deeper look at a most important measure of ion concentration using a simulated physical determination. Young chemists prepare a series of dilutions after determining a dilution factor for the...

What's the solution to gaining insight into your class' progress? Give this brief quiz a try! Part 10 of a 14-installment series on states of matter tests learners' skills in the areas of dilution and the properties of water,...

Students model solutions with beakers of colored glass or plastic spheres. In this solutions lesson plan, students use beakers of colored spheres to represent pure substances. They mix the spheres to demosntrate solutions. They discuss...

Students determine that the relative concentration of copper ions in water can be determined by a color comparison. They make a copper (II) sulfate solution of a given concentration. Students dilute their initial solutions until their...

Mixtures and solutions are different; one can be separated fairly easily and the other cannot. This hands-on experiment was written specifically for learners with visual impairments or blindness. They will use lemonade and trail mix to...

Use indirect measurements to monitor metabolic activity in plant cells. Scholars understand that cells with a higher metabolic rate have a higher concentration of catalase enzyme. They use this information to compare metabolic rates of...

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.

Do antacid tablets really do what they claim? An experimental activity attempts to answer this question. Individuals practice the process of titration during the first part of the experiment. They then use those skills to neutralize an...

There's no risk of injury when working with virtual HCl! Challenge your young chemists with making calculations to create a 3M solution of HCl from the concentrated acid. They first calculate the correct ratios of HCl and water and then...

Why do rocks break down over time? Learners explore this concept by simulating physical and chemical weathering of different types of rocks. They use an abrasive to demonstrate physical weathering and acid to demonstrate chemical...
