The Solution to Pollution is Dilution
Students consider what happens to herbicides or insecticides that are used in agricultural practices, especially herbicides that are used to control noxious weeds. They become acquaint with a chemical assessment method known as...
Curated OER
Classifying Chemicals
In this acids and bases worksheet, students identify the strengths of acids and bases and indicate the concentration of hydronium and hydroxide ions. They determine if given chemical formulas are acids or bases, they find the molarity...
Curated OER
Chemical Equilibrium
In this chemical equilibrium worksheet, students review hydration, dissociation, and colligative properties. Students also review Le Chatelier's principle. This worksheet has 15 short answer questions and 12 problems to solve.

Solutions
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...
Curated OER
Dilutions
In this dilutions worksheet, students calculate molarity of solutions and practice figuring out the volume of concentrate needed for a specific dilution of solutions. This worksheet has 4 word problems.
Curated OER
The Chemicals of Living Cells
Designed to be a study guide or self assessment for high school biologists, the learning exercise has good questions about cell chemistry, but would need to be reformatted if you want your kids to write their answers on the paper. There...
Curated OER
PH Neutralization For Pollution Control
Students recognize whether a solution is an acid or a base. In this acids and bases lesson plan, students use chemicals and identify if those chemicals are acids or bases. From the conclusion, students will be able to identify if the...
Curated OER
Chemical Weathering
Eighth graders comprehend the effects of chemical and mechanical weathering. They comprehend the differences between the two forms of weathering and the various agents involved in both forms of weathering. Students complete a...
Curated OER
Chemical Equations
In this chemical equations worksheet, learners are given the trends for the reactions between the alkaline earth metals with water, the solubility of the Group II hydroxides and the solubility of the Group II sulphates.

Chemical Reactions
In this chemical reactions activity, students calculate the molar mass and the rate of reaction for the given chemical reactions. This activity has 3 problems to solve.
Curated OER
Additional Aqueous Solution Review Problems
In this solutions worksheet, students balance chemical equations, classify reactions by the type of reaction it represents, and review the solubility rules. Students practice working out double displacement, neutralization, and dilution...
Curated OER
Parts-Per-Million Concentration Lab
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...

No Stomach for It: Investigating Antacid Medication
You won't get a stomachache doing an investigative experiment. Pupils simulate the effect of antacids on stomach acid. Obviously, they won't be using real stomach acid; diluted hydrochloric acid serves this purpose.
Nuffield Foundation
Investigating Enzymes Used in Laundry Detergent
It's a win-win situation: learn about enzymes and get clean clothes, too. Young scientists add enzymes to a dilution of laundry detergent. They apply them to stained fabrics to determine the effectiveness of the enzyme-filled detergents.
