Summer SAVY, Session 4 Day 3, “Wonders of Electrochemistry” (7th-8th)
SAVY Families,
Today in Wonders of Electrochemistry, students explored the mechanism and real-world applications of electroplating, which is the process of coating a conductive object with a thin metal using electrochemistry fundamentals. Specifically, our content outcomes included students knowing (1) the process of electroplating and how industries use electrochemistry for manufacturing and (2) real-world applications of multiple, diverse electrochemical processes. To achieve this, we began with a session spotlight about metals in everyday objects and how electrochemistry is used to enhance durability, reduce costs, and improve appearance.
In our hands-on electroplating demonstration, students used vinegar, copper, and a battery to coat a quarter with a thin layer of copper (making it look like a penny), observing firsthand how metal ions can be transferred through a solution. This simple setup led to thoughtful discussions about corrosion resistance, material efficiency, and why coatings are often used instead of solid metals. From jewelry to electronics to aerospace, we discovered how a thin layer of metal can make a big impact. We divided into small teams where students created their own discussion boards that included many, many examples of electroplating that we use every day. Later in the afternoon, students conducted industry research, exploring how electrochemistry is used in fields like medicine and renewable energy. They presented their findings and reflected on how metal reactivity influences material choices.
What stood out most today was how quickly students connected these concepts to larger themes of sustainability, innovation, and design. Many expressed surprise that such a seemingly simple process could have such wide-ranging applications, from electric vehicle manufacturing to medical implant coatings. Students also participated in collaborative discussions and reflected on how electroplating may evolve with future technology, including nanomaterials and environmentally friendly practices.
As always, we ended the day with thoughtful reflection to conclude what we learned. Some “Think Beyond” questions to ask your student include:
- What happened during the electroplating experiment?
- What are some of the electroplating examples included on your team’s discussion board?
- Why are certain metals used for coating?
- How is electrochemistry applied in modern industries?
Tomorrow, we will turn our focus to biosensors and how electrochemical reactions are used in health technologies. I am so excited to see what the day brings!
Best regards,
Ms. Richards
