If you've ever been to or watched sporting events, you've probably seen several sports drinks on the sidelines. Why? Sports drinks are filled with electrolytes, which your body loses as you sweat; it's important to replenish them!

Do sports drinks really provide more electrolytes than other drinks, such as orange juice? Use this electrolyte challenge sensor kit to find out!

With this electrolyte test kit, middle school and high school students can learn all about electrolysis and how to measure electrolytes' concentration in a solution. This electrolyte challenge sensor kit comes with all the materials needed to build your own electrolyte sensor - an engaging, hands-on, DIY science activity!

  • Orange Juice vs. Sports Drink: Does Gatorade have more electrolytes than orange juice?
