Key concepts students will learn:

  • Living organisms maintain homeostasis, which is a regulated balance of internal conditions, such as temperature and water concentration.

  • All living things must have metabolism, meaning they capture and use energy through chemical reactions like photosynthesis or cellular respiration.

  • Living organisms can reproduce, either simply like bacteria copying DNA or more complexly with sperm and egg cells uniting.
