5 Engaging Ways to Teach Electrolysis Without Lecturing

Hasan Amjad

Electrolysis, the fascinating process of using an electric current to drive non-spontaneous chemical reactions, has been a staple in the chemistry world for decades. Considering its importance, it is usually taught in basic chemistry courses.

However, at times, teaching this intriguing subject can be challenging for educators as it involves abstract concepts and complex equations. 

To help educators bring the magic of electrolysis to life in their classrooms, we have curated a list of 5 engaging ways to teach this vital topic. 

1. Engage Learners With Interactive Models

Electrolysis can often seem like an intangible concept to students, as they are typically exposed to intricate equations in their textbooks. They don’t get to observe the actual process. Interactive models are an excellent approach to overcome this problem. 

Interactive models provide students with a clear visual representation of the electrolysis process. This makes it easier for them to understand the movement of ions and their role in electrolysis.

Some interactive models, like Labster’s Electrolysis simulation, offer a controlled environment for students to experiment with different electrolytes, electrode materials, and experimental setups. In this particular simulation, students design and build an electrolytic cell to fuel a rocket on Mars while understanding the basic concepts of electrolysis.

2. Add fun With Games and Activities

Educators can make the learning journey enjoyable, fun, and exciting by adding interactive games that test knowledge as well as horn their problem-solving skills. 

You can create a set of trivia questions about electrolysis, covering topics such as types of electrolytes, electrode reactions, and applications of electrolysis. Divide the class into teams and take turns asking each team a question.

Another interesting activity could be designing an electrolytic cell. Make small groups and provide each group with a set of materials, including a battery, wires, and two electrodes. Once a group sets up the experiment, ask them to identify the products formed as a result of the chemical reaction. 

These activities promote collaboration and critical thinking in students, making your lessons more productive and engaging. 

3. Harness the Power of Modern Tools

You can also enhance students' understanding of electrolysis by providing interactive and engaging learning experiences. Use virtual reality systems, simulations, and animations to describe the electrolysis process.

With 3D animations or simulations, the process becomes more accessible since they can visually understand how ions segregate and travel to different electrodes. And how the processes of oxidation and reduction take place at these electrodes.

An excellent resource in this regard is Labster electrolysis simulation, in which students can virtually experiment and build an electrolytic cell with existing components. They manipulate and observe the different aspects of the process through its schematic diagram.

4. Inspire Students through Career Exploration

Helping students connect their learning to potential careers can inspire and motivate them to engage with the subject matter. 

Discuss various careers related to electrolysis, such as electrochemists, chemical engineers, and environmental scientists, and highlight the role of electrolysis in these professions. 

Encourage students to research and present specific job profiles. This gives them a broader perspective on the potential real-world applications of their knowledge.

5. Relate it to the Real-World: Cite Applications

Chemistry, in general, is considered one of the most complex subjects as students fail to understand its relevance in the real world. Mostly that is due to the educators who unintentionally overlook highlighting the practical applications. However, there are plenty of examples that can be cited. 

One interesting application to quote students is metal extraction. Metals are found in nature as ores. Electrolysis is used to extract and refine these metals, such as aluminum, copper, and gold. 

The electroplating of jewelry items and utensils is another household application of electrolysis. In electroplating, a thin layer of one metal is deposited onto the surface of another metal to make it shiny, smooth, and corrosion-resistant. 

With these practical applications, students can understand the relevance and significance of the subject in various industries and everyday life. This sparks interest in the subject and motivates them to explore further.

Regardless of your experience as a chemistry educator, implementing these strategies can motivate your students to explore the captivating realm of ions, electrodes, and electric currents.
