This short video describes the difference between conductors and insulators. It is short, extremely clear, and easy for your students to understand. This video could be shown during a mini lesson for electrical circuits to help students grasp this concept. I really enjoyed the fact that this video was made by another teacher, because she knew how to make an effective video for all students. Definitely a great resource for teaching electrical circuits!
