For example, when the weather turns cold, bears return to their dens and hibernate for the winter. When the environment changes, life responds to those changes. All living things respond to changes in the world around them. All living things consume energy (they eat food), and use that energy for work, play, and growth. Mammals, like whales and giraffes, do so by giving birth to young. Think of a tree – it has roots to absorb water, a trunk and branches, and leaves to absorb sunlight.Īll living things have the ability to reproduce, or procreate. All lifeforms exist in a body of some kind that is highly organized. There is order and structure to living things. All lifeforms have similar characteristics or behaviors, too. On the inside, all lifeforms have tiny structures inside their bodies that are almost exactly the same and help them do all the things that they need to do so they can live – things like walking, flying, or swimming, and even basic functions like breathing and digesting food. ![]() (K-ESS2-2, K-ESS3-1)Īll living things on Earth have a lot in common. (K-LS1-1) *Systems and System Models: Systems in the natural and designed world have parts that work together. Patterns: Patterns in the natural and human designed world can be observed and used as evidence. LS3.B: Variation of Traits: Individuals of the same kind of plant or animal are recognizable as similar but can also vary in many ways. Plants also are very much, but not exactly, like their parents. LS3.A: Inheritance of Traits: Young animals are very much, but not exactly, like their parents. Plants also respond to some external inputs. Animals respond to these inputs with behaviors that help them survive. LS1.D: Information Processing: Animals have body parts that capture and convey different kinds of information needed for growth and survival. Plants need water and light to live and grow. They obtain their food from plants or from other animals. LS1.C: Organization for Matter and Energy Flow in Organisms: All animals need food in order to live and grow. Plants also have different parts (roots, stems,leaves, flowers, fruits) that help them survive and grow. ![]() Different animals use their body parts in different ways to see, hear, grasp objects, protect themselves, move from place to place, and seek, find, and take in food, water and air. LS1.A: Structure and Function: All organisms have external parts that they use to perform daily functions.
