Students research chemical formulas and balance chemical equations.  In this chemical equations instructional activity students complete a class activity on chemical equations and answer questions.

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 periodic table worksheet, students review atomic mass, molar mass, and percent composition of compounds. Then students complete 4 problems.

It's all in the family with this presentation! The halogen, alkali metal, and noble gas families are introduced to young chemists along with characteristic properties and colorful diagrams of electron shells. Viewers are then taught how...

Third graders study the concept of light as an energy source.  In this energy lesson students participate in a lab that show them the concept of light as an energy source. 

Fifth graders study the properties of metals and use them to identify different properties.  In this metal properties lesson students complete a demonstration .

Students discuss what the m in E=mc2 represent. They relate that mass in a chemical reaction is always conserved. Students convey that atoms rearrange themselves in chemical reactions to form different molecules and compounds.

In this empirical formulas worksheet, students 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 mass and...

In this chemistry worksheet, students solve chemical equations and define terminology using previous knowledge. There are 8 review questions.

In this balancing equations worksheet, students use an on line source to answer questions about balanced equations and they write balanced equations for various types of reactions. They balance equations using an on line game that allows...

Eighth graders read and interpret the Periodic Table. They also make decisions on how to group and arrange different kinds of matter and draw the structure of atoms of pure elements. Finally, 8th graders contrast and compare basic...

In this elements and bonding worksheet, students classify given elements, they identify valence electrons in atoms, they explain the reactivity of elements, and they explain why certain atoms gain electrons while others lose electrons.

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

For this energy worksheet, students are given a table of the many measurements of energy. They solve 6 problems converting from one measurement of energy to another using the conversion factors given.

Students differentiate physical and chemical change. In this chemistry instructional activity, students list examples of those changes. They apply what they learned in a Jeopardy style team game.

In this bonding worksheet, students read about the two different types of chemical bonding: ionic and covalent bonds. Students review ion notation and oxidation numbers. This worksheet has 24 fill in the blank, 2 drawings, and 4 short...

In this minerals worksheet, students 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 create models of structural isomers, geometric isomers, and polymers.  In this chemistry lesson plan, students are given definitions and molecular model kits to create a variety of different isomers and polymers.

In this oil, fossil fuels and Earth's atmosphere worksheet, students answer 3 questions about the origin of oil and its uses, the effects of burning oil and fossil fuels on the Earth's atmosphere and the origin and maintenance of the...

Students investigate relative mass using 8 different items. In this relative masses lesson plan, students discuss as a class John Dalton's atomic theory. They take the masses of the 8 items and record their data. They discuss relative...

In this Lewis structures worksheet, students are given molecules that they must draw Lewis structures for and identify the total number of electrons. They also calculate charges on molecules, determine stability and draw the Lewis...

Students investigate foods. For this biology lesson plan, students will conduct testing on different types of foods as they learn about different molecules that make them up. Students will also learn about the shapes of the molecules.

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 moles activity, students read about mass, formula mass and moles. They calculate the masses of given numbers of moles of compounds and they calculate the number of moles of given masses of compounds.
