Can your classes solve the problem of the smelly sweat sock? Young scientists complete a lab investigation that begins by using electrochemistry to generate colloidal silver. They use their solutions to test the rate of microbial growth to prove or disprove claims that colloidal silver can inhibit microbial growth. Limit the microbial growth and smelly socks are no longer a problem!
