4th Grade Life Science Curriculum

A comprehensive 4th Grade Life Science curriculum is currently being developed and tested in local classrooms to teach all of the 4th Grade Food Web and Ecosystems Standards. These lessons were developed by the Moorea Coral Reef LTER Education Coordinator.

Food Chain Hide and Seek

OBJECTIVES:
Students will learn:
• The basic interactions between consumers in a food chain (predation, competition).
• The number of damselfish in an area can influence how many
damselfish die due to predation, termed density-dependence.
• Pollution decreases the amount of coral habitat available for shelter, which will contribute to the number of damselfish
that die due to predation.

STANDARDS:
California State Science Standards, 4th Grade
Life Science, Energy and Matter, 2abc

In Hot Water


OBJECTIVES:
Students will learn:
•Temperature is influential in determining the geographic range organisms, in this case kelp forests and coral reefs.
• Interactions with both the living and non-living components of an
organism’s ecosystem are essential for an organism’s survival.
•Solar heat and the spinning of the Earth create wind patterns and ocean circulation gyres that affect an organism’s survival.

STANDARDS:
California State Science Standards, 4th Grade
Life Science, Ecosystems, 3ab
Investigation and Experimentation, 6ace

Connected Ecosystems

OBJECTIVES:
Students will learn:
• Ecosystems are made of animals and plants (biotic) working together with the abiotic (non-living) components of their habitat, such as light, temperature, food, and shelter.
• Interactions with both the living and non-living components of an organism's ecosystem are essential for an organism's survival.
• Natural ecosystems go through cycles, which can be altered by natural and human-induced disturbance.

STANDARDS:
California State Science Standards, 4th Grade
Life Science, Ecosystems, 3ab

Ecosystem Assessment Lab


OBJECTIVES:
Students demonstrate their understanding of ecosystem structure by creating:
Option 1: the perfect organism, adapted to the biotic and abiotic components of their habitat, or
Option 2: a unique food web, complete with the complex predator-prey relationships of producers and consumers in their system

By justifying their designs, students will show they have learned the materials and progressed to applying the concepts in new situations.  This lesson works well as a follow-up toa field trip experience to an aquarium or local body of water, but can also be done using your students' imagination.
