In this matter exam, students answer 80 multiple-choice and short-answer questions on atomic structure, atomic bonds, and equations related to energy spectra. A scientific calculator is recommended. A student's answer sheet and an answer...

A covalent bond yells at an ionic bond, "Didn't anyone teach you to share?" Four matching puzzles allow pupils to review covalent, ionic, and metallic bonding. They apply logic and problem solving to complete gridlocks including the...

Who knew atoms could be attracted to each other? A simulation allows learners to see how forces between atoms influence the attraction between them. Classes see the attractive and repulsive forces adjusting as distance between atoms...

In 1897, J.J. Thomson discovered the electron, the first subatomic particle proven to exist. Scholars review their understanding of electrons, protons, and neutrons as they work through the puzzles. Each puzzle connects two or three...

In chemistry, the mole is a unit of measurement, much like a millimeter or liter. After learning about moles, scholars learn various equations relating to mass, volume, and concentration. They review each of these equations in a few...

Flame tests determine if there is a specific metal in a chemical compound. Young forensic scientists review their understanding of flame tests and hydroxide precipitates by solving puzzles. The timed review encourages mastery.

Is your class in a quandary over quantum numbers? Change things up by adding games to the mix! Science scholars discover the shape, number of electrons, and number of orbitals in the s, p, and d sub-shells using an interactive.

When water is a solvent in a chemical equation, we consider it an aqueous solution. Scholars match the name of four states of matter to their proper symbol in a chemical equation. Four puzzles provide repetition to help pupils remember...

Did you know in the UK a quart is smaller than in America? This explains why a standard unit of measure is necessary for volume. Young scientists learn the similarities and differences between five different units used to measure volume....

The largest chemical reactors are blast furnaces, used to make iron from ore. Scholars explore reactants by first matching each one to its purpose and formula. Then, a series of three gridlock puzzles reinforce the content while...

Explore the interactions between various combinations of two atoms. Observe the the total force acting on the atoms or the individual attractive and repulsive forces. Customize the attraction to see how changing the atomic diameter and...

Simulations to show students the nature of chemical bonds. Simulations include an explanation of stereochemistry, atomic orbitals, chemical polarity, formation of an atom, and a summary quiz.
