Summer SAVY, Session 4 Day 2, “Wonders of Electrochemistry” (7th-8th)
SAVY Families,
Day 2 of Wonders of Electrochemistry was action-packed with discoveries, challenges, and meaningful discussions! Today, we focused on the dynamic duo that makes electrochemistry tick: oxidation and reduction reactions, also known as REDOX reactions. We started the day by thinking critically with our ice breaker, “What could we use to power our devices?” Students shared ideas ranging from batteries and oranges, setting the stage for a deeper dive into the science behind it all.
In our morning session spotlight, we broke down redox reactions: what they are, how electrons are transferred, and why these processes are essential for generating electricity. To apply their knowledge, students worked in pairs on a hands-on activity, classifying equations into oxidation and reduction processes. Not only did they sharpen their chemistry skills, but they also learned to justify their reasoning and collaborate effectively with peers. The excitement continued with our DIY Electrochemical Circuit experiment, where students built simple circuits and observed how redox reactions could power a basic device. They were amazed at how chemical energy could be transformed into electrical energy through such accessible materials!
In the afternoon, we shifted gears and explored real-world applications, such as electric vehicle batteries, in a collaborative discussion. We examined what makes a good battery and how electrochemistry drives innovation in the clean energy sector. During our group discussions, we tackled big questions: Why do some metals corrode? How do electric vehicles rely on redox reactions? What environmental impacts arise from battery production and disposal? These conversations helped students connect chemistry to everyday life, even though we cannot always see chemistry in action. Students then conducted their own research for their final electric vehicle presentation!
To cap it all off, students analyzed real-world examples of battery waste and energy efficiency with an introduction to the lithium-ion battery crisis. We wrapped up with a reflection, and many students shared how surprised they were to see how relevant redox chemistry is to the world around them, from smartphones to electric cars. Some “Think Beyond” questions you can ask your student at home include: What happens when a metal corrodes? How do redox reactions make electric vehicles run? What is a battery (not what a battery does)?
Tomorrow, we will dive into electroplating with some shiny surprises! This class continues to impress me with their enthusiasm and insight!
Best Regards,
Ms. Richards
