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...

In this ionic bonding worksheet, students observe diagrams about ionic bonds and crystal formation. They answer 37 short answer questions about the properties of monatomic ions, polytomic ions and write correct formulas.

Young scholars design and create a compost pile in order to study the Nitrogen Cycle. They then use the scientific method to determine if plants grow better when they add organic matter from their compost pile to the plant's soil.

Fifth graders investigate the nitrogen cycle and examine the concepts of decomposition and nitrification. Students participate in a class discussion about the creation of waste and ammonia compounds, then using nitrogen cycle cut-outs...

For this chemistry review worksheet, learners explore their knowledge of solutions, acid and bases, nuclear reactions, and radioactive decay as they answer 33 matching, fill in the blank, and short answer questions.

Ninth graders are shown a constructed machine and they asked what it is and what it does? They are questioned on type of simple machine constructed. Students are questioned on various parts of machine. They work in groups to design...

In this oxyanions worksheet, students identify the common polyatomic ions. They write formulas and name polyatomic ions based on IUPAC rules.

In this molecules worksheet, students research a substance that is made up of molecules with two or more elements. Students name the substance, write a short description of the substance, and draw a picture that illustrates the substance.

Second graders study about air pollution and the effects it has on our Earth. Students tally cars on a sheet that has been categorized as follows: One person in car, two persons in car, or three or more persons in car. Students go to...

Students examine a recyling bin and the many different items that can be recycled. They practice loading the recyclie bin and using the correct vocabulary to explain each item.

Students receive and interpret copies of US Constitution and Iroquois Constitution. Then they reference (look up) the articles mentioned by Daly in the Iroquois Constitution text, and analyze for parallel meaning in the US Constitution....

Sixth graders complete several experiments about chemical and physical changes. In this physical and chemical science activity, 6th graders complete 6 experiments about chemical and physical changes. Students examine the processes of...

Students determine how scientists measure pollutants in food and the environment. Students discover how scientists remove one material based on its physical properties. Students figure out how much of a pollutant is present after...

In this leaf chromatography worksheet, students separate the pigments of a leaf using paper chromatography. They answer 4 questions about their results and draw the colors they observe on their chromatogram from the leaf.

Young scholars discover how President Eisenhower's brand of diplomacy at this Pennsylvania farm temporarily eased the tensions of the Cold War.

This compact collection of slides explains the history and use of the mole unit. Relative atomic mass, as John Dalton understood it, is explained. Avogadro's number is also introduced. The mole, or the unit for the amount of a substance,...

In this science worksheet, learners explore the learning outcomes for a unit on chemical reactions. Students define 60 vocabulary words and answer a list of questions for each topic.

Designed to be a study guide or self assessment for high school biologists, the learning exercise has good questions about cell chemistry, but would need to be reformatted if you want your kids to write their answers on the paper. There...

Opening with a chart of common polyatomic ions, and finishing with an explanation of how  to name polyatomic ions, this presentation is to the point. The links on the vocabulary page do not work, leaving you only a few slides to...

A flashy PowerPoint includes clear summaries of atomic structure and electronic configuration. Dot and cross diagrams will help viewers learn how to draw an atom. As a result, learners should be more clear how electronic configuration...

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...

Young scholars collect and look at rocks and write down information about them in science notebooks. They make comparisons and sort the rocks according to their properties, and then discuss their findings with their classmates and put...
