Students participate in experiments to help them determine the concentration of an unknown solution. They graph a standard curve and plotting the relationship between the concentration and the amount of light needed. They discuss their...

Students work together to create mini-molar concentrations of HCI. They record and analyze their data for specific results. They answer discussion questions to complete the lesson.

High schoolers investigate the effects of temperature and concentration on the rate of reactions. In this "clock reaction" kinetics lesson plan, students change the concentration of one reactant and keep the second constant. An indicator...

In this molarity instructional activity, students determine the concentration or molarity for each of the solutions. Students manipulate the molarity formula to calculate the moles, mass, or volume of each problem.

Enhance your class' ability to understand solubility. Science scholars examine how temperature and concentration affect solubility using an interesting lab experiment. The introduction and procedure also discuss the relationship between...

One way to study something is to try to replicate it. Young scientists do just that as they use solutions to recreate mineral structures on a dwarf planet. They make solutions with different types of salt, evaporate them, and observe the...

How does temperature affect lipase activity? Young scholars conduct an experiment to collect data on the interaction of lipase at different temperatures. They add lipase to a solution of milk, sodium carbonate, and phenolphthalein and...

What happens to the enthalpy of a reaction as the concentration of reactants varies? Learners explore this question with a virtual lab activity. They consider five different solutions of the same reactants and monitor the temperature...

In this solutions worksheet, students review the properties of solutions, the polarity of molecules, molarity, and solubility curves. This worksheet has 8 short answer questions and 15 problems to solve.

The end was just the beginning. The period immediately after the end of World War II and the Holocaust is often called "The Return to Life" as survivors looked to reunite and recreate broken families and shattered lives. A two-lesson...

Resistance to the Holocaust took on many forms. Learners explore the passive and active resistance of Jewish people who continued their practices and observances, as well as organized resistance against the evils of the Nazis. An...

In this dilution worksheet, students determine the final concentrations of solutions after a specific amount of water has been added. This worksheet has 4 problems to solve.

In this acids, bases and salts activity, high schoolers solve five problems in order to determine the molarity of solutions or the volume of substances to be added to make molar solutions. They also solve five dilution problems about acids.

In this equilibrium worksheet, students read about the factors that effect equilibrium in solutions such as the pressure of the solution, the temperature and the concentration of the solution. They answer three multi-part questions about...

In this pH worksheet, students answer ten questions about acids and bases as well as pH. They determine the pH given concentrations of ions in a solution. they also describe various types of acids and bases.

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...

In this acid and base worksheet, learners solve five problems using the volume and molarity of solutions in order to find the concentration of the acid or base in each given problem.

Students perform a redox titration of iron. In this iron titration lesson plan, students use potassium permanganate to oxidize iron so they can determine the percentage of iron in a sample of fertilizer.

Your young landscapers do concentration calculations in this problem dealing with mixing fertilizer. Learners use and analyze rational expressions within this context.

Take a look at linear functions in a new environment. A three-stage algebra project first asks learners to model the salt concentration of an aquarium using linear functions. Then, using iterations, pupils create a set of input-output...

Chemistry stars calculate ion concentrations, pOH, or pH in different solutions. For questions in the latter half of the worksheet, they also have to explain why a solution is acidic, basic, or neutral and solve for molarity of a solute....
