Designing the right package — it's more than a pretty picture. Challenge small groups to design a food package. They must consider the type of food they are packaging and the package's ability to control the physical and...

Study the chemistry of mining! Through nine lessons in the unit, learners explore different concepts related to mining. Their study ranges from rock and mineral analysis to the environmental impact of dynamite and the chemical reaction...

Can your young chemists identify the most commonly used chemicals in the lab? Introduce the class to the go-to substances in most middle and high school chemistry experiments with an interactive. The resource offers timely feedback as...

Although only 4 slides long, this brief presentation summarizes how to balance equations very clearly.  There is an example of how to balance equations incorrectly, followed by some rules and guidelines that show the correct...

How exciting would it be for your chemistry class to produce their own "gold"? This experiment allows pupils to witness the chemical reaction of copper pennies as they react with zinc and sodium hydroxide to produce "gold" tokens. It is...

How long do fresh foods last in space at the International Space Station? Which foods perish quicker than others? How can astronauts preserve their foods to make them last longer in space? Young scientists test the rates at which...

In this chemical reactions worksheet, high schoolers solve 53 problems including balancing equations, writing the names of acids, matching the names of compounds with their chemical formulas, and identifying types of reactions.

Students illustrate the molecular nature of matter and show that chemical change involves alteration of molecules.

In this acids and bases learning exercise, learners 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,...

Students study polyatomic ions and write binary and ternary ionic chemical formulas. They explore putting together different monatomic ions and coming up with as many chemical formulas as possible. They play a game similar to memory...

Second graders identify physical and chemical changes of matter. They distinguish between physical and chemical changes. They classify changes as physical or chemical.

In this chemical reaction principles worksheet, students read about definite proportions and the law of conservation of mass. Students read about how to balance a chemical equation. Then students complete 20 fill in the blank, 2 short...

Students classify compounds as ionic or covalent. In this chemical bonding lesson plan, students experiment with 6 chemical compounds. They test physical properties such as the melting point, the solubility and the electrical...

In this rusting, burning and oxygen learning exercise, students read about chemical reactions and are given diagrams of a rusting bicycle, a burning candle, and a variety of chemical changes. Students make observations and explain the...

In this naming and writing chemical formulas learning exercise, high schoolers are given directions and practice writing simple chemical formulas. They identify positive and negative valence elements, they name nonmetal compounds, they...

In this chemical reactions worksheet, students experiment with several different reactions and identify each as a single replacement, double replacement, synthesis, decomposition or combustion reaction. Students observe the changes in...

In this chemical equations worksheet, young scholars balance equations. This worksheet has 22 chemical equations to write out and balance.

This two-part Chemistry learning exercise first prompts students to predict the products of reactions of two different chemicals in 15 questions. Students are then asked to provide the balanced equation and type of reaction for two...
