Conductors and Insulators in Electricity

Jacob and Sam from Science for Kids explore electricity by testing various objects to determine if they are conductors or insulators. They use a battery, light bulb, and alligator clips to create circuits and test materials like metal, plastic, and graphite. The video concludes with a summary of findings, highlighting that metals are good conductors, while most non-metals are insulators, except for graphite.
