Scientific studies show the older we get, the more acidic we become. The activity extensively teaches high schoolers about acids and bases. By the end of the 14th installment of 36, they can define and explain three concepts of...

Across the top of the page is a large Z diagram representing varying degrees of acid-base equilibria. Advanced chemistry classes answer eight questions using the values listed for the H+ and the OH- ions that are part of the...

Amphoteric compounds act as both an acid and a base. Scholars apply their knowledge of the four oxide types while completing four puzzles. They match a sample of each type of oxide with the corresponding reaction.

In an electrolytic cell, electrical energy is converted into chemical energy, the exact opposite of a battery! Lesson 15 in a series of 36 explores electrochemistry. Participants begin by reading and discussing oxidation/reduction...

Practice naming chemical compounds or stating the formula when given the name. Discover how well you have mastered these skills either by time or percentage correct.

Students balance chemical equations and solve for gram to mole ratios.

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