For 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 study the difference between types of ionizing radiation and how elements are transmuted. They determine that radiation is normal and surrounds us. They calculate the amounts of alpha, beta and gamma radiation emitted from a...

In this elements instructional activity, high schoolers compare and contrast the characteristics of metals and non-metals. Students practice drawing Lewis dot diagrams and writing ion notation. This instructional activity has 9 word...

Ninth graders investigate ionic bonding through energy level diagrams. For this ion bonding lesson plan, 9th graders observe demonstrations to show energy level diagrams using magnets to represent the subatomic particles. Students fill...

Students build a model and observe the cycle of evaporation and condensation that occurs in the water cycle. They see how the water cycle works, such as water condensing on the side of the jar and drops precipitating into rain that...

Students determine crude oil can be separated into useful fractions by a process of fractional distillation. They write a balanced equation for the reaction between a hydrocarbon and oxygen.

In this nuclear decay worksheet, students read about alpha and beta decay and the isotopes formed by the reactions. Students solve nine problems including writing the equations for the decay of radioactive isotopes, identifying the...

High schoolers divide substances into categories: made of chemicals/not made of chemicals, synthetic/naturally occurring, and toxic/nontoxic. They observe a mystery chemical and determine what precautions they need to take when handling...

High schoolers generate a radioactive decay table for an imaginary element using a box filled with pinto beans and M&M's. They use their data to plot a decay graph, develop the concept of half-life, and use the graph to "age" several...

Eighth graders investigate chemical reactions to produce polymers. In this polymers lesson plan, 8th graders experiment with sodium silicate and ethyl alcohol to make a polymer. They also experiment with borax and glue to make a polymer....

In this elements instructional activity, students use the relative atomic masses of given elements to calculate the relative formula mass. Students calculate the mass of compounds from given number of moles and determine the number of...

Students investigate moles and Avogadro's hypothesis. In this moles lesson plan, students complete a worksheet by finding the volume of 1 mole of each substance given its density and they find the number of molecules, the formula, the...

In this enthalpy learning exercise, students calculate the combustion for propane and find the enthalpy of the reaction. They discuss entropy and free energy.

Discover the change of the seasons by modeling the Earth-Sun system. Learners model the orbit of the Earth around the sun and explore how and why the patterns of winter and summer occur.

In this chemistry calculations review worksheet, students solve 33 review problems about titrations, precipitates, pressure and volume of gases, combustion reactions, heat of combustion, molar concentrations and molecular formulas.

In this matter worksheet, students watch a movie and then compare the differences between compounds and mixtures. This worksheet has 16 fill in the blank questions.

In chemistry, organic means something contains a carbon base. A helpful presentation starts by defining macromolecules as large organic carbon molecules. Scholars answer questions about each topic on the associated worksheet. It covers...

Students review atomic numbers, positive and negative charges, and the periodic table. They examine the relationships among protons and electrons, location of various elements, electron energy levels, and oxidation numbers.

Students engage in a lesson that is concerned with the concepts related to solution chemistry. They calculate the molar mass of various chemical compounds. Then students predict the anion ratio for ionic compounds. Students also write...

Young scholars define the properties of minerals and their uses in their world. In this multi-instructional activity unit, students contribute actively to discussions of mineral mining, mining methods and mine safety. A role play...

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.

Students recognize that the fundamental building block of all organic and inorganic matter is the atom. They construct models of a sugar, fatty acid, amino acid and nucleic acid and describe their roles.

In this chemistry worksheet, students use the periodic table to complete the chart shown, filling in all of the missing information in the blank spaces. They identify and describe various elements found in the periodic table.

In this chemical compounds worksheet, high schoolers review the different types of bonding, define the octet rule, and draw Lewis structures (electron-dot diagrams) for given compounds. This worksheet has 7 fill in the blank, 5 short...
