In this chemical reactions activity, students are given the reactants of equations and must complete each equation by writing the products and balancing the equation. They must also identify the type of reaction.

Twenty chemical combinations are described for which high school chemists write out balanced equations and identify the physical state for each reactant and product. In some cases, no reaction would occur, so they need to be able to...

To provide practice in balancing chemical equations, you can give your class this worksheet. It is straightforward, easy to read, and thoroughly tests for understanding of this vital skill in general chemistry. Those who complete this...

A series of math and science activities feature M&M's® as manipulatives to help kids work through equations. The resource includes exercises on finding averages, percent of compositions, moles in chemical reactions, genotypes and...

If you need a way to assess the concepts in your physical science class, use an extended set of worksheets as a midterm or final exam. It includes questions about density, physical and chemical matter, speed and velocity, weight and...

Cellular respiration and photosynthesis relate closely, but many don't realize how. Scholars drag and drop the reactants and products to the chemical reactions for both processes. Then they answer three multiple-choice questions.

Produced in the UK, this handout contains a chart of cations and anions. It explains how ionic compounds are formed and named. This is a concise and attractive handout that can be useful as a reference for your chemistry apprentices.

Middle schoolers discuss the chemicals found in second hand cigarette smoke. In this second hand smoke activity, students observe a demonstration of a smoke analyzer. Middle schoolers research the chemicals found in second hand smoke and...

For this expressions and operations worksheet, 9th graders solve and complete 10 different multiple choice problems that include various types of expressions. First, they determine the complete factorization of a given trinomial. Then,...

Third graders explore forms of matter through reading, hands-on science activities, and research using the Internet. Students create a booklet, directions given, that they title and decorate, to later serve as a review visualization...

Students create a rocket using Alka-seltzer of baking soda and vinegar. In this physics lesson plan, students identify the factors affecting the length of time the rocket is propelled. They relate this activity to actual rocket launched...

Students discuss the importance of safety in the science lab and also in industry. They also will understand some of the implications of chemistry in the world using links provided.

Students investigate the 1950's pollution tragedy in Minamata, Japan. The elements of dose, response, individual susceptibility, potency, and threshold of toxicology are explored in this lesson plan.

Students examine the variation among responses of seeds to the same dose of the same chemical. In reviewing their seed investigation, students note that sometimes not all seeds in the same bag responded in the same way.

Students study oxidation and define vocabulary pertinent to it.  In this oxidation lesson students make predictions and create experiments

In this chemistry worksheet, 10th graders write the names for 12 element symbols. They complete a chart by writing the element names next their symbols.

In this chemistry worksheet, 10th graders write the symbols for 12 elements that are named in a table. They complete the chart by writing the names in the blanks next to each element name.

Students define the words "reversible" and "irreversible." They complete a worksheet that shows a number of changes. Students must decide which are reversible and which are irreversible.

In this compound worksheet, students will write down 1 example of a compound and will then write in 3 specific details to support their example.
