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...

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...

Curdle milk on purpose. Pupils mix vinegar with milk to produce curds and then explore the properties of the curds. Scholars redo the experiment by changing up one of the variables and observing what happens.

Carbon dioxide is on the rise; does that also mean a rise in danger to humans and animals? Scholars learn what that means for the environment and more specifically the ocean. They examine data on the pH of different ocean areas and learn...

It's all about the scale—they're not just wires, they're nanowires! The second lesson of the series builds on the oxidation-reduction experiment in the first lesson. Scholars synthesize a sample of nanowires using electrolysis. As they...

Create a coat of armor for dinosaur volunteers. Young scientists explore the oxidation-reduction reaction facilitated by electric current. The result of the reaction is a dinosaur coated in copper and zinc, which leads to an...

Microchips are a man-made wonder. Investigate the manufacturing wonder with a hands-on inquiry-based lesson. Scholars simulate the process of pattern transfer using photoresist. Their conclusion identifies how their process replicates...

Surface area certainly surfaces as a variable for chemical reaction rates. Scholars perform an experiment to discover how the size of catalysts affect the rate of a chemical reaction. They record their results in tables and graphs to...

What a big job for such a small particle. Young scientists learn about the role of nanoparticles in catalytic converters for cars. They conduct an experiment to create alginate-MnO2 catalytic spheres. 

Your class is bound to be fascinated by this virtual lab! Young biochemists explore molecules that bind to specific sites on the DNA molecule through a skillful simulation. The lesson challenges learners to create a DNA-bound solution...

Why do the bases in DNA pair up the way they do? Unravel the mystery of the double helix in a virtual lab. Young scientists follow in the footsteps of Watson and Crick to determine the free energy associated with DNA base pair binding....

Colorful cobalt complexes make a great way to learn about Le Chatelier! Eager chemists explore equilibrium through a virtual lab. Individuals use solutions with two different concentrations and observe the color changes that indicate...

How does carbon dioxide affect the world's oceans? The final installment in a series of six lessons has pupils research ocean acidification, then conduct an experiment to witness the delicate balance that exists in our seas. Materials...

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...

No one likes kidney stones, but they are very interesting to learn about. The last installment of a three-part unit has learners experiment with different chemicals to see which one inhibits the growth of calcium oxalate crystals (which...

Candy rocks! A sweet lesson offers a different take on the rock candy experiment. Groups use a supersaturated sugar solution to create rock candy. Pupils then add other ingredients to the solution to test their effect on the...

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...

Le Chatelier's interest in thermodynamics and building materials such as cement and plaster led to the Le Chatelier Principle in 1884. Activity 13 in a series of 36 extensively explores chemical equilibrium. Learners read about...

All chemists know that moles are made of molecules. Individuals see how changes in the amount of solute affect the concentration of the solutions. By manipulating solute amounts (moles), solution volume (liters), and solute types, the...

The best part of learning about equilibrium is that nothing changes. Young chemists observe four demonstrations during this lesson: equilibrium in a saturated solution, equilibrium with an acid-base indicator, equilibrium with cobalt...

Household materials can be used for more than cleaning! In this collaborative experiment, emerging chemists use products such as vinegar and liquid antacid to explore chemical reactions that commonly occur in the human body.
