πŸ“š Quick Study Guide

  • β˜€οΈ Day and Night: 🌍 The Earth's rotation on its axis causes day and night. One full rotation takes approximately 24 hours.
  • πŸšΆβ€β™€οΈ Walking: 🦴 Involves complex coordination between your brain, muscles, and skeletal system. Newton's Third Law of Motion (action-reaction) plays a crucial role.
  • 🍎 Eating: πŸ§ͺ A chemical process where your body breaks down food to obtain energy. Enzymes and acids in your digestive system aid in this process.
  • πŸ‘οΈ Seeing: πŸ’‘ Light reflects off objects and enters our eyes. The lens focuses the light onto the retina, which converts it into electrical signals that the brain interprets.
  • πŸ”₯ Heating: 🌑️ Heat transfer can occur through conduction (direct contact), convection (movement of fluids), and radiation (electromagnetic waves).
  • πŸ’§ Water Cycle: πŸ”„ The continuous movement of water on, above, and below the surface of the Earth. Key processes include evaporation, condensation, precipitation, and collection.
  • 🌱 Plant Growth: 🌳 Plants use photosynthesis to convert light energy into chemical energy. The basic equation for photosynthesis is: $6CO_2 + 6H_2O + light \rightarrow C_6H_{12}O_6 + 6O_2$
