Max Born and Fritz Haber developed the Born-Haber cycle in 1916, which is used for measuring enthalpy that otherwise couldn't be measured. Young scientists solve four matching puzzles using their knowledge of the stages, standard...

One document contains five different worksheets for practice naming and writing formulas for ionic compounds. The first is particularly notable, as it systematically walks beginning chemists through the process of using the periodic...

Students identify and describe the building blocks that make up an atom. They also compare the ages of atoms to the ages of the materials they compose,as well as, give examples that illustrate the small size of atoms.

Students practice naming and writing formulas for simple chemicals. After a review of vocabulary, they create ion flash cards and discuss the rules for writing chemical compounds. They practice naming and writing the formulas based on...

In a comprehensive role playing activity, teens play the parts of different stakeholders in the realm of acidic oceans. They research, debate, and create a presentation from the perspective of either ocean organisms, the fishing...

High schoolers record information from the periodic table for sodium and chloride. They determine whether salts are molecular or ionic compounds, along with sodium chloride's molecular weight, and relative weights

Students explore the components of matter. They discover what matter is, the states of matter, and how heat and cold cause it to change states in an online format. In addition, they complete internet-based lessons, activities, and quizzes.

Students differentiate physical and chemical change. In this chemistry lesson, students list examples of those changes. They apply what they learned in a Jeopardy style team game.

Students practice with writing and balancing simple chemcial equations. they comprehend that chemical equations are a method of using a set of univeral symbols to represent what happens experimentally in chemical reactions. Pupils...

Students write the electron configuration of elements in the ground state. In this chemistry lesson, students draw how subatomic particles are arranged in the atom. They construct Lewis dot diagrams of valence electrons.

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

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...
