Students develop a comprehension of parts per million as a concept. They work in teams to create successive dilutions of a solution to reach a parts-per-million concentration. Students list what they think the atmosphere is made of. They...

For this buffer solution activity, high schoolers experiment with the addition of different solutions to a buffer solution and observe the changes in pH using a pH probe. Students describe the differences between adding pure water and...

In this solutions worksheet, students determine the molarity of a solution after it has been diluted to a specific volume. This worksheet has 12 problems to solve.

Eighth graders examine different solutions.  In this solution material instructional activity students complete a lab activity and several worksheets. 

Students identify diffusion and its processes through experimentation and calculations. They also use a CBL and conductivity probe to measure the conductivity of various solutions and study the effect of concentration gradients on the...

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

You'll need to concentrate on the concentration lab to get it done. Given a virtual beaker with a silver chloride solution of unknown concentration, scholars find the silver ion concentration in the solution. Of course, they must show...

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...

Test the levels of vitamin C in different juices. After a instructional activity on the importance of vitamin C in our diets, learners use titration to determine the vitamin C content in juice. They use their experience with the...

Colorful cobalt complexes make a great way to learn about Le Chatelier! Eager chemists explore equilibrium through a virtual lab. Individuals use solutions with two different concentrations and observe the color changes that indicate...

Feeling a little neutral about your pH and pOH teaching strategy? Perk it up with engaging puzzles! Young scientists relate ion concentration to pH and pOH, as well as the dissociation constant for water. The resource is available as an...

Sometimes playing games in class isn't a bad thing. Science sleuths evaluate and calculate pH and pOH with an online resource. They then manipulate concentration information and relate it during a series of puzzles.

So, you've headed out into the wilderness and forgotten your camp stove? What's a chemist to do? Solutions may be the solution! Scholars use a virtual lab workbench to create solutions that would be capable of heating food, courtesy of a...

What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists...

Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...

According to John Betjeman, "Childhood is measured out by sounds and smells and sights, before the dark hour of reason grows." With The Boy in the Striped Pajamas film study, scholars work in small groups to discuss the quote and other...

You'll feel strongly about this weak acid and base virtual lab! Scholars experiment with the wonders of dissociation constants in a simulated lab environment. The accompanying written work includes buffer preparation, titration curves,...

Students discuss the difference between concentration and solubility as well as examine the difference in a hands-on activity. Using water and table salt, they experiment with solubility. They create different concentrations using water...

Learners calculate the concentration of different solutions. In this chemistry lesson, students explain what a solution is. They explain ways to change the concentration of a solution.

In this chemistry worksheet, students look for the weight of acid and examine its mass using chemical equations and a laboratory procedure.

Most things naturally strive for balance, and acids and bases are no exception. Neutralization of acids and bases allows scholars to explore the color changes associated with the pH scale. After this exploration, pupils neutralize two...

Three lab guides are given here that detail experiments to illustrate the oxidation of glucose for the production of ATP. The first will compare photosynthesis and respiratio and show theimporatnce of both to plants. The next will show...

This isn't your typical basic lesson—it's more acidic! Learners use pH information to determine the hydroxide ion concentration of different substances and then use these values to analyze information. The calculations require...

The first two pages provide a chart to complete with results of a lab test using different solutions and indicators. The data analysis questions will help your students understand the concentrations of the solutions and how they affect...
