Three experiments involving pennies help young chemists see the chemical reactions between copper and other elements. The first experiment is rhetorical (it prompts students to leave a bright penny out for a year) but the second two...

The process for balancing chemical equations is stepped through slide by slide in this presentation. For some strange reason, the subscripts for certain elements are not dropped down on the first slide only, so you may want to copy the...

A short paragraph helps explain how covalent bonds are formed, and then your class will complete the Electron/Dot and Structural diagrams for the molecules given.  The valence diagrams will reinforce understanding. This activity...

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 background information presented by the teacher and read dictionary definitions for the words "organic" and "synthetic." In this gardengin lesson, students complete a worksheet on the material. Students grow and compare...

In this chemical and physical change worksheet, students use a sugar cube and observe its physical properties both when it is whole and after it is crushed. They heat the sugar cube and record 5 properties of the matter while being...

Students create a model of the USDA's Food Pyramid Guide, using shoe boxes. They bring an assortment of shoe boxes from home. Students are given a copy of the "Food Guide Pyramid." They wrap boxes for the bread group in white, the...

Young scholars verbalize a simple particle theory, They apply their particle theory to explain what happens during chemical reactions and how this theory supports the law of conservation of matter. Pupils comprehend that the atomic...

Students explore the components of matter. They discover what matter is, the states of matter, and how heat and cold cause it to change states in an online format. In addition, they complete internet-based lessons, activities, and quizzes.

In this quantities in chemistry instructional activity, students solve 13 review problems about percent composition, significant digits, the mole, simple and molecular formulas, balancing equations, stoichiometry, limiting reagents and...

Students calculate the densities of several liquids that appear similar.  In this physical science lesson, students go beyond understanding the way liquids of different densities behave to researching how this knowledge applies in...

Students describe visual, textural, and other physical qualities of sample rock specimens. Using compare and contrast skills, students sort and classify the specimens according to their assessments of the qualities present in each....

Students visually distinguish between those rocks that appear to be made of one substance, vs. those that appear to have more than one. This leads to the distinctions that indicate the different types of rocks: igneous, sedimentary and...

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

In this chemistry worksheet, students select answers to 24 multiple choice questions using the drop down box. They identify the different atoms involved in the chemical reaction.

In this atoms worksheet, learners review protons, neutrons, electrons, molecules, compounds, and ions. This worksheet has 10 fill in the blank and 3 problems to solve.

Students complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson, students complete 8 lessons to learn about matter, its states, and how to measure matter.

In this radiochemistry instructional activity, students read about how scientists learn more about elements using radioactive isotopes. Students answer three critical thinking questions about the reading and radiochemistry.

In this oxidation state activity, students are given rules for assigning oxidation numbers and a chart showing the oxidation states of the elements of a given compound. Students use the rules and the example to find the oxidation states...

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...

In this bonding worksheet, students read about the octet rule in bonding, ion notation, ionic bonds, covalent bonds and oxidation numbers. Students write 2 ion notations, they determine if 8 sets of ions will make compounds, they draw 2...

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...

For this Lewis structures worksheet, students read about drawing Lewis structures and how to identify valence electrons. They draw Lewis structures for eight given compounds.

Learners listen to a song that teaches the elements of the periodic table and write their own song to be used as an aid in remembering scientific information.
