Students explore the concept of molecular modeling and differentiate between saturated and unsaturated compounds. In small groups, they identify molecular formulas, complete a chart comparing alkanes, alkenes, and alkynes, and construct...

Students follow carefully designed instructions to bond silver to glass thus creating a mirror. The process used, Brashear's Process, uses sugar rather than formaldehyde to reduce the compounds, but many of the chemicals are dangerous,...

Seventh graders explain the role of stratospheric ozone and predict at least three ways in which depleted ozone would change her/his lifestyle. They then describe the process by which chlorine or bromine compounds can break down ozone...

In this organic chemistry of alkenes worksheet, students name and write the chemical formulas for 12 alkenes and then complete 3 short answer questions about the saturation of alkene compounds.

In this empirical formulas worksheet, high schoolers read about determining empirical formulas from chemical formulas. They determine the empirical formula given ten molecular formulas. They also find the molecular formulas given the...

Learners conduct a series of experiments to explore carbon dioxide properties. In this chemistry lesson plan, students explain the production and uses of this gas. They measure its amount in soda and waste product of yeast.

For this chemical reactions worksheet, students review the oxidation number rules and then assign oxidation numbers to atoms in given compounds. Students identify the reducing agent and the oxidizing agent in reactions. Students practice...

In this isomers worksheet, students define isomers and then draw the different isomers for the given chemical formulas. This worksheet has 30 problems to solve.

This instructional activity would provide a great assessment for teachers to test student knowledge. Learners are asked to complete 3 charts which characterize types of chemical bonds such as alkanes, alkenes, or alkynes. They must also...

In this organic reactions worksheet, students are given descriptions of the seven types of reaction of organic compounds. They then answer six questions about these reactions.

Students research certain elements and then analyze their potential bonds with other elements in a dating game where the dating pool is comprised of the elements featured on the Periodic Table.

For this minerals worksheet, learners read about the relationship between elements, rocks and minerals. They experiment using 6 different colored gumdrops to represent 6 common elements. Students construct gumdrop and toothpick models of...

Students investigate bio-fuel. In this investigative lesson, students create bio-fuel from vegetable oil waste. Students will analyze, predict, collect and synthesize data from their experiments with bio-fuel.

In this scientific investigation worksheet, students follow the provided procedures to examine the chemical reactions of hydrogen and oxygen atoms and then respond to 1 short answer question.

Students work in small groups with a small set of 8 nuts and 5 bolts to assemble into combinations of 1 nut: 1 bolt, and 2 nuts: 1 bolt. They explore the outcome and discuss. Then a student mixes two clear, colorless solutions together...

Young scholars describe characteristics and common uses of acids and bases. They describe the role of natural indicators in the chemistry of acids and bases after testing and making observations on a variety of plant extracts. Students...

Students use models to visualize molecular structures. Students read about Lewis dot structures, hybridization, and formal charge. Then students build and draw the molecules and ions given. Students complete 11 pre-lab questions and 4...

In this word search worksheet, students locate 20 words related to science. The word list includes volume, mixture, and solute.

In this chemistry of life worksheet, students will review key terms of plant cell structure and chemistry by reading 13 clues to complete the puzzle. Word bank is included.

Students brainstorm what matter is and how they define it. They construct a water molecule with marshmallows and toothpicks. In addition, they watch videos to explore the use the idea of nanoscience to investigate the properties of...

Students investigate the concept of a polymer using an experimental design of protecting an egg in a bookbag. They test the properties of polymers and form an educated solution to the proposed problem. Then they describe the steps used...

Students recognize and name the products used to build a hamburger. They review the USDA Food Guide Pyramid. Students are given worksheets, and they match the burger parts to the picture parts. They conduct a taste test on samples of the...

Students view a video about the formation of precipitates. They complete a worksheet that asks them to identify what makes a compound form and what holds it together.

Students explain the role of stratospheric ozone and predict at least three ways in which depleted ozone would change her/his lifestyle. They then describe the process by which chlorine or bromine compounds can break down ozone molecules.
