In this chemistry activity, students work to write the chemical formula and the names for the compounds after the elements have been combined.

For this chemistry worksheet, students determine the number of water molecules is a given volume of water. Students determine the empirical formula for given compounds from the percentage mass of elements. This worksheet has 20 problems...

In this classifying materials worksheet, learners match a set of substances with their description and properties, then identify a set of elements and compounds.

Students identify the characteristics of aerosols. Using remote sensing, they participate in an experiment in which they determine how the sun's radiation and elements in the atmosphere interact with one another. They also research the...

The purpose of this lesson involves reviewing nomenclature and molecular formulas as well as introducing naming molecular compounds and identifying acids. The students investigate and understand how conservation of energy and matter is...

In this oxidation numbers learning exercise, students compare metals and nonmetals, draw Lewis Dot Diagrams, and determine the oxidation number for the given elements. This learning exercise has 1 multiple choice, 5 short answer, and 12...

Young scholars write the electron configuration of elements using the Aufbau principle. In this chemistry lesson, students build their own key that demonstrates the principle.

Fourth graders improve their understanding of Graham's Law by using properties of gases to evaluate the rate of effusion of two compounds as they vaporize. They engage in a lab which elevates their understanding of the properties of gases.

Students observe the behavior of termites and draw conclusions about their behavior. They record data as to termite behavior and recognize elements in the experimental design which must include a hypothesis.

Young scholars differentiate between point and non-point pollution and determine how the different types of pollution are harmful to aquatic ecosystems. They complete a series of tests on a sample of "polluted" water and a sample of...

Though this is meant to be second in a two-part lesson, the two are not dependent on each other. Pupils play the roles of visible light rays, light or dark surfaces, and carbon dioxide molecules. They interact and react according to...

In this electronegativity worksheet, students complete a chart given 10 molecules. They draw their Lewis structures, they draw the shape of the molecule, they determine the difference in electronegativity between the bonds, they...

For 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.

Learners describe the history of materials. They use the kinetic (particle) theory to explain changes of state in matter and trace the flow of heat during changes of state and chemical changes.

Students observe a demonstration on the role of thermal conductivity in heat transfer.  For this thermal conductivity lesson, students design and conduct an experiment to compare the thermal conductivity of four substances....

Students examine solubility and the significance of water.  In this aqueous solution lesson students complete a lab activity on soil profiles.

Wow! This is one of the most exhaustive presentations on finding chemical formulas that you will come across! Beginning with the basics, and leaving junior chemists with procedures and concrete examples, this PowerPoint certainly...
