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.

Students identify principles behind acid-base reactions. They predict factors that may affect an acid-base reaction. Students identify questions and concepts that guide scientific investigations.

Students support the law of conservation of matter with evidence. They discuss the changes observed from the burning of the candle, and the differences in mass which are observed when the same reaction is carried out in an open or...

Unique properties of hydrogen, its production, and reaction with other elements make this slide show uncommon. The appearance, however, is common with plain white background and only black and red font, a formatting issue on the second...

There is not much information in this presentation. It serves more as a guide to direct the flow of your introductory chemistry lecture. Each slide displays a large title and a smaller phrase meant to explain it. For example, one title...

Students study how to complete thermochemical equations.  In this equation lesson plan students learn how to manipulate equations to calculate energy changes and reactions.

Students conduct a series of investigations on the unique properties of water. In this general science lesson, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Determine physical properties of potential packaging materials. Continuing from previous lessons in the series, the resource asks groups to identify physical properties of the substances. They test for conductivity, solubility, water...

Only 10 percent of an incandescent bulb's energy is used to create light; the remaining 90 percent is heat. In the unit of activities, young chemists examine energy through hands-on activities, videos, discussions, and...

Students treat a high molecular weight polyvinyl alcohol polymer with potassium periodate. They measure the viscosity of polyvinyl alcohols.

This is an apt assignment for chemistry takers that are studying ionic solutions. Eight questions require problem solving and critical thinking to answer. The first question instructs learners to use a table in the textbook, but you can...

Students evaluate their reaction to a series of statements to investigate that personal choices are based on personal goals, peer and social pressures, ethic and religious beliefs, and the knowledge of biological consequences. This is...

Students study silicon and where it comes from.  In this solar mining lesson plan students complete an Internet search of mining and a lab activity. 

Young scholars identify the periodic table trends and predict material properties. They also design and conduct simple experiments and test material properties. Finally, students compare and contrast material properties and that...

Tenth graders examine chemical reactions.  In this chemistry lesson students choose an investigation that they wish to perform based on their interest.

Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

For this battery worksheet, students read about oxidation-reduction reactions and voltaic cells. They are given a diagram of an electrochemical cell and they answer four questions using the cell. They also identify the anode given two...

In this chemistry worksheet, students determine the number of atoms in each element and select one that is not equal on both sides of the equation. Then they add a coefficient in front of the formula with that element and adjust their...

In this gas stoichiometry worksheet, students use the ideal gas law and balanced chemical equations to solve for unknown values such as volume and mass of gases.

High schoolers discuss the layers of the atmosphere, and the history of the ozone hole. They discuss the chemistry of the ozone formation. Students compare seasonal data collected with ozonesondes. They compare Antarctic and Arctic ozone...

For this equilibrium worksheet, students read about phase equilibrium and dynamic equilibrium. They answer nine questions based on their reading and their background in chemistry.
