  1. Electricity is about how electrons interact with atoms. Electrons can move from one place to another, creating electric current in conductive materials like metals.
  2. Conductors, like metals, allow electrons to flow freely, while insulators hold onto their electrons tightly. This difference determines how well materials conduct electricity.
  3. The movement of electrons in a wire is what allows us to use electricity for various tasks. It can be quick, but individual electrons move slowly compared to the speed at which electrical signals travel.

  1. When a whale dies and sinks to the ocean floor, it becomes a feast for many sea creatures. This event leads to a chaotic but vital ecosystem around the whale carcass.
  2. After larger scavengers eat their fill, bacteria step in to break down the whale's body, turning it into nutrients for other life forms. This process creates a thriving community in a place that usually has little life.
  3. The cycle of life and death in the ocean shows that nothing goes to waste. Even in death, a whale can support new life for decades, reminding us that everything in nature is interconnected.
