Observing the Effect of a Change in Conditions on a System at Equilibrium by Applying Le Chatelier's Principle

Do you have young scientists wanting to make new discoveries rather than just completing the same experiments? Young scientists use their observational skills to identify animals and patterns in animal behavior. Through tracking...

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

Is qualitative or quantitative research more convincing when it comes to climate change? In the eighth lesson during this 21-part series, scholars begin by performing a quantitative analysis of deforestation and urbanization. Then, they...

Would you believe that your digestive system stretches to five times your height?! Help your pupils to understand this relationship as they work through the laboratory exercise. The first instructional activity of a 12-part series is a...

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...

When compounds react with each other, the rate of the forward reaction and the backward reaction are the same when the reaction is in equilibrium. However, if other factors come into play, such as an increase in temperature, or the...

Sometimes chemistry is a balancing act. Get to know Le Chatelier's Principle with a video from the JFR Science playlist. The narrator discusses pressure, temperature, and concentration in chemical reactions and how they affect the...

Build a strong foundation for your teaching of stability and change! The video addresses the Next Generation Science Standards Cross-Cutting Concept through insightful examples. The narrator includes ideas for introducing the standard in...

Equilibrium reactions are able to reach a steady state of products and reactants, but what happens when this careful balance is disturbed? With the help of this instructional video, young chemists learn to apply Le Chatelier's...

Identify how Le Chatelier's Principle predicts changes in concentration when "stressing" reactions at equilibrium. [14:39]
