What are the consequences and costs of inflation? What is CPI, and how do we calculate it? This resource answers these questions in an organized and in-depth manner, and also includes a worksheet of follow-up questions designed for...

Students explain and use ideal gas law and use the law to solve problems. They use conversion factors to convert mass to mol. Also students use stoichiometry skills previously learned.

Students conduct a series of experiments to explore Graham's law. In this chemistry lesson, students differentiate effusion and diffusion. They perform calculations using Boyle's, Henry's, Charles' and Graham's Laws.

For this pressure and kinetic theory worksheet, students review Dalton's Law of Partial Pressure, the Kinetic Molecular Theory of Gases, and Graham's Law of Effusion. Students then solve 5 problems using these equations.

In this gases worksheet, students use the concepts of Graham's Law of diffusion to determine the velocity of gases and molecules. They describe kinetic energy and how it relates to the mass and velocity of objects.

Middle schoolers explain the laws of volume and pressure, identify what a limiting reagent is and why it is important in a chemical reaction, and distinguish between fossil fuels and renewable energy sources.

In this gas law worksheet, learners learn how Graham's law governs the diffusion of gases. Students calculate the velocity and effusion rate of gases at certain temperatures. This worksheet has 6 problems to solve.

Students discuss laws and their importance. They discuss silly or unique laws and explore the process that must be followed to make a law.

Students identify the physical properties of propane by applying the gas laws to them. They compare and contrast Charles's and Boyle's gas laws and complete problems using them. They discuss their answers to end the lesson.

Water is the only molecule on Earth that can naturally exist in all three states of matter. The interactive simulation shows different molecules changing states of matter with the addition or removal of heat. Learners then see how...

Sixty multiple-choice questions test on a variety of first year chemistry subjects. In order to succeed, exam takers must be competent with properties of elements, stoichiometry problems, gas laws, bond dissociation, and types of...

Students demonstrate Graham's Law by observing a gaseous diffusion. After a lecture/demo, students perform an experiment then complete a write up activity which is imbedded in this plan to reinforce what they have observed during the...

Students work in small groups and use a hand-held vacuum pump with a balloon under the dome with some air. Another deflated balloon is attached to the end where the air goes out. As the air is drawn out of the dome the first balloon with...

Eighth graders investigate different gas behaviors. In this chemistry lesson, 8th graders describe how changing volume and temperature affect gas particles motion. They collect data and make a generalization about these variables'...

In this reaction rate worksheet, students determine the molecularity of a reaction plus show that the predicted rate law equals the experimental rate law. This worksheet has 3 problems to solve.

Middle schoolers design and construct a paper rocket that can be launched with a drinking straw. They participate in a lecture and read an article about rocketry and how Newton's Third Law applies to rocket launches. Each student...

Eighth graders use lab work and software to collect and analyze pressure and temperature data in order to illustrate the relationship between the temperature and pressure of a gas at a constant volume. They conduct a lab and organize...

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for...

Tired of waiting for hot water? Groups of three determine the efficiency of an electric water-heating device. They calculate the amount of energy it takes to heat the water and the theoretical amount of energy required to heat the water....

Not all energy sources are renewable, as learners investigate in this unit. Made up of six lessons that span a few weeks of instruction, the unit has learners examining US energy reserves and consumption, using data to draw conclusions...

What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists...

Can your class tell the difference between a burette and a pipette? Develop their lab apparatus knowledge using a series of puzzles. The online activity associates the name, image, and sizes of burettes, pipettes, volumetric flasks, and...

In this periodic table worksheet, students complete a paragraph containing facts about the periodic table by filling in 18 terms from a word list.

In this chemistry worksheet, students identify and explain what Boyle's Law is and what it changes. Then they describe Charles' Law and how the temperature of gas changes so does the volume.
