Have you been searching for environmentally friendly chemistry experiments to use in your high school laboratory? This stoichiometry experiment replaces a conventional aluminum to alum lab by using sodium carbonate and calcium chloride...

Teaching is a balancing act! Keep things on an even keel with a comprehensive equilibrium lesson plan. The resource covers reversible and irreversible reactions, Le Chatelier's Principle, and the industrial applications of equilibrium...

Whoa! What just happened? That's right, change is everywhere. But what exactly is changing? Middle school science sleuths get to the bottom of the changes matter can experience. Through simple demonstrations, engaging videos, and an...

Just like the old saying goes, "What goes in must come out." This simulation allows pupils to balance chemical equations. The introduction gives three examples before scholars switch to game mode, pick their level, and continue to...

Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the lesson uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a hands-on activity, scholars...

Fritz Haber was awarded the 1918 Nobel Prize, but 30 years later was considered a war criminal. This video provides the story of Fritz Haber as well as Henry Louis Le Chatalier, who is much more famous though he considered himself a...

College-level or AP chemists use phthalic anhydride to synthesize two different polyesters, one linear and one cross-linked in structure. A detailed materials list and well-written procedures are provided on a lab sheet. Learners write...

Keep it simple with this chemistry assignment. Learners examine an acid-base titration graph and answer four questions about the data. Then they will balance neutralization equations and calculate molarity for several specific solutions....

This 60-question comprehensive exam was designed to determine who would go on to compete in the 2000 US National Chemistry Olympiad. Hopefuls answer multiple choice questions regarding all chemistry topics taught in the first year...

Only eight problems are on this competitive national chemistry exam. It required the balancing of chemical equations, solving stoichiometry questions, and more. This is part two of three of the national exam. Also available is a local...

Sal introduces students of chemistry to "Stoichiometry," which is the calculation of measureable relationships of the reactants and products in a chemical reaction. Sal sets up a balanced chemical equation and then, using the Periodic...

Students are introduced to the process of balancing chemical equations. First, students see that a chemical equation describes the chemical reaction that takes place when two elements are combined together. In the world of chemistry,...

You're bound to get a reaction from your classes with this experiment! Scholars perform several chemical reactions, make observations, and classify the reactions as single replacement, double replacement, composition, or decomposition...

Cookies and chemical equations have a lot in common! Using cookies as a reference, scholars learn to balance chemical equations. Pieces of the cookies represent different parts of the compounds and elements. This is the sixth installment...

More than half of AP Chemistry test takers earn a high enough score to get college credit. Improve that statistic by using past test questions including precipitate, molarity, and chemical equations to prepare for a future exam. The...

The College Board published the mean score on the 2016 AP Chemistry exam as a 2.69, but a minimum of a three is required to earn college credit. Help pupils study for the upcoming exam with actual test questions, sample answers, and...

More than 83,000 scholars earned college credit, thus saving time and money by passing the AP Chemistry exam in 2017. Use the exact test questions covering concepts from activation energy to solubility to prepare for the upcoming...

2018 saw some of the highest AP Chemistry scores in years. The College Board released each test question covering topics from enthalpy to net ionic equations, as well as scoring guidelines and more to benefit future scientists. Example...

Highlight DNA solution with fluorescent dyes! Scholars use dye to determine the concentration of a DNA solution. As the dyes bind with the DNA solution, learners make conclusions about the limiting reactants.

Play a little game of concentration! A virtual lab investigation allows learners to predict the products and reactants of a DNA reaction. They make their calculations and then test their predictions in the lab workbench.
