Unit 3- Relationships and Requirements of Living Things
Fourth Grade Unit 3: Relationships and Requirements of Living Things
Big Ideas (Key Concepts)
• Plants and animals have basic requirements for maintaining life, which include the need for air, water and a source of
energy (food).
• Organisms have observable traits and physical characteristics that help them survive and reproduce in their
environments.
• Organisms are a part of a food chain or food web where food/energy is supplied by plants, which need light to produce
food/energy.
• Plants and animals can be classified by observable traits and physical characteristics.
• Fossils provide evidence that life forms have changed over time and were influenced by changes in environmental
conditions.
Relationships and Requirements of Living Things Content Statements and Expectations
L.OL.E.1 Life Requirements – Organisms have basic needs. Animals and plants need air, water, and food. Plants also require light. Plants and animals use food as a
source of energy and as a source of building material for growth and repair.
L.OL.04.15 Determine that plants require air, water, light, and a source of energy and building material for growth and repair.
L.OL.04.16 Determine that animals require air, water and a source of energy and building material for growth and repair.
L.EV.E.2 Survival – Individuals of the same kind differ in their characteristics, and sometimes the differences give individuals an advantage in surviving and
reproducing.
L.EV.04.21 Identify individual differences (color, leg length, size, wing size, leaf shape) in organisms of the same kind.
L.EV.04.22 Identify how variations in physical characteristics of individual organisms give them an advantage for survival and reproduction.
L.EC.E.1 Interactions – Organisms interact in various ways including providing food and shelter to one another. Some interactions are helpful; others are harmful to the organism
and other organisms.
L.EC.04.11 Identify organisms as part of a food chain or food web. 6
L.EC.E.2 Changed Environment Effects – When the environment changes, some plants and animals survive to reproduce; others die or move to new locations.
L.EC.04.21 Explain how environmental changes can produce a change in the food web.
E.ST.E.3 Fossils – Fossils provide evidence about the plants and animals that lived long ago and the nature of the environment at that time.
E.ST.04.31 Explain how fossils provide evidence of Earth’s past.
E.ST.04.32 Compare and contrast life forms found in fossils and organisms that exist today.
