Overview:

Ecosystems are constantly going through gradual changes. Sometimes those changes are natural, and sometimes they are caused by humans.

The classroom resource provides a video that will describe how ecosystems can change over time due to natural and human activity. There is also a short test that can be used to assess students' understanding.

Content Standard(s):
Science
SC2015 (2015)
Grade: 7
Life Science
7 ) Use empirical evidence from patterns and data to demonstrate how changes to physical or biological components of an ecosystem (e.g., deforestation, succession, drought, fire, disease, human activities, invasive species) can lead to shifts in populations.


NAEP Framework
NAEP Statement::
L8.8a: All organisms cause changes in the environment where they live.

NAEP Statement::
L8.8b: Some of these changes are detrimental to the organisms or other organisms, whereas others are beneficial.


Unpacked Content
Scientific And Engineering Practices:
Analyzing and Interpreting Data
Crosscutting Concepts: Stability and Change
Disciplinary Core Idea: Ecosystems: Interactions, Energy, and Dynamics
Evidence Of Student Attainment:
Students:
  • Use information gained from data patterns and analysis to demonstrate that any change in an ecosystem can lead to shifts in populations.
Teacher Vocabulary:
  • Empirical evidence
  • Patterns
  • Data
  • Ecosystem
  • Populations
  • Physical components (e.g., water, air, temperature, sunlight, soil, etc.)
  • Biological components (e.g., plants, animals, etc.)
  • Phenomena (e.g., deforestation, succession, drought, fire, disease, human activities, invasive species, etc.)
Knowledge:
Students know:
  • Ecosystems are dynamic in nature and can change over time.
  • Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations.
  • Changes in the physical or biological components of an ecosystem (e.g., rainfall, species introduction) can lead to changes in populations of species.
Skills:
Students are able to:
  • Demonstrate the scientific idea that changes to physical or biological components of an ecosystem can affect the populations living there.
  • Identify and describe the given evidence needed to demonstrate the scientific idea that changes to physical or biological components of an ecosystem can affect the populations living there.
  • Evaluate the given evidence, identifying the necessary and sufficient evidence for supporting the scientific idea.
  • Use reasoning to connect the evidence and support an explanation using patterns in the evidence to predict the causal relationship between physical and biological components of an ecosystem and changes in organism populations.
Understanding:
Students understand that:
  • Changes in the amount and availability of given resource may result in changes in the population of an organism.
  • Changes in the amount or availability of a resource may result in changes in the growth of individual organisms.
  • Resource availability drives competition among organisms, both within a population as well as between populations.
  • Resource availability may have an effect on a population's rate of reproduction.
