Students research information using various internet resources. For this chemistry lesson, students demonstrate their ability to navigate websites and gather necessary information. They evaluate the potential usefulness of the databases...

Students participate in lab activities in which they examine immersion, stain resistance, and stress cracking of synthetic polymers. Students use their collected data to discuss service applications and possible performance of materials.

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

Focus on oxidation-reduction reactions with a review worksheet. Junior chemists answer short-answer questions before they write balanced half-reaction and full-reaction equations.

Melting and burning might seem like opposites, but both exist as common examples of exothermic reactions. Scholars work with three different exothermic chemical reactions to determine the enthalpy changes. They measure and mix chemicals,...

Don't overreact! A simple experiment demonstrates chemical reactions as scholars mix chemical solutions and metals in a large well plate. They note all changes to the metals, solutions, precipitate, colors, and more. A full data table...

Here is a short, but well-rounded review of redox reactions. Chemistry apprentices identify the type of reaction, write half-reaction equations, balance equations, and assign oxidation numbers. Being brief, this would make a purposeful...

Here is a chemistry worksheet that was designed for a specific textbook section dealing with oxidation-reduction reactions, but it can be used in conjunction with any general chemistry curriculum. To complete the page, learners must...

Some of kids' favorite toys are the products of science experiments. Scholars follow precise measurements to mix and create their own slime and Play-Doh. They observe the changing textures and the chemical reactions throughout the...

Here is a straightforward practice test for first year chemistry learners. Responders balance equations, identify types of reactions, represent electron configurations, and solve stoichiometry problems. Keep this handy to use as...

A list of word reactions are given. Your class should write balanced equations, along with giving the reaction type and physical states.

Students observe what happens when sugar is dissolved in water and when it is heated. They weigh the products after each of the two experiments on a balance scale. Pupils distinguish between physical and chemical changes. Students are...

Students comprehend that a chemcial change produce substances with a different composition and physical and chemcial properties. They state the differences between physical and chemical changes. Pupils observe changes that occur during...

Eighth graders explore the chemical and physical properties of a variety of elements in a lab setting. They organize the data they collect onto a spreadsheet and then choose one element from the periodic table to research. They...

Students explore how chemical reactions occur. After a brief discussion of household chemicals and how they work, students prepare a solution of invisible ink. Students create a message with their ink and watch the reaction as their...

In this chemical reaction worksheet, students write 11 balanced equations for 11 word equations, and complete word equations and balance chemical equations for 13 chemical equations.

In this classification of changes worksheet, students identify each example as either chemical or physical changes. Students also classify other examples as either element, compound, solution, colloid, or suspensions. In the other...

Students describe and define chemical reactions. They design a laboratory experiment, collect data and analyze data.

In this enthalpy equation worksheet, students are given 3 examples of chemical reactions. Students then respond to 4 practice problems and 1 challenge problem in regard to heat and energy change and release.

In this compounds activity, students name the given compounds from its chemical formulas and write the chemical formula from the compound name. This activity has

Eleventh graders study the use of the periodic table to develop a better understanding of the chemical elements.

Learners apply their comprehension of colligative properties to real-world situations. They review the concepts of physical and chemical changes. Students are reminded that science is used extensively in food-production. They are...

Students work in pairs to complete a worksheet that asks them to balance several chemical equations. They partner with other students to correct the equations and then follow online instructions to create a table in Word.

Students explore ten different stations that demonstrate either chemical, kinetic, or mechanical energy. They examine the way energy is transferred during each station's hands-on activity. Stations include vinegar and baking soda,...
