Brine Shrimp 2: Brine Shrimp Survival


Content Source:

Science NetLinks
Type: Lesson/Unit Plan


In this lesson, students will develop an understanding of how the growth and survival of an organism depends on physical conditions. This is accomplished by designing an artificial environment in which brine shrimp can thrive. This lesson is the second of a two-part series on brine shrimp. In Brine Shrimp 1: Hatching Brine Shrimp, students determined the optimum salinity for hatching. In this lesson, students will raise brine shrimp, designing an artificial environment in which they can survive.

Life Science
11 ) Analyze and interpret data to predict how environmental conditions (e.g., weather, availability of nutrients, location) and genetic factors (e.g., selective breeding of cattle or crops) influence the growth of organisms (e.g., drought decreasing plant growth, adequate supply of nutrients for maintaining normal plant growth, identical plant seeds growing at different rates in different weather conditions, fish growing larger in large ponds than in small ponds).

NAEP Framework
NAEP Statement::
L8.10a: For some characteristics, inheritance is more important; for other characteristics, interactions with the environment are more important.

NAEP Statement::
L8.10b: The characteristics of organisms are influenced by heredity and environment.

Scientific And Engineering Practices:
Analyzing and Interpreting Data
Crosscutting Concepts: Cause and Effect
Disciplinary Core Idea: Ecosystems: Interactions, Energy, and Dynamics
Evidence Of Student Attainment:
  • Predict, using analysis and interpretation of data, how both environmental and genetic factors influence the growth of organisms.
Teacher Vocabulary:
  • Analyze
  • Interpret
  • Data
  • Predict
  • Environmental
  • Conditions (e.g., weather, resource availability, etc.)
  • Genetics
  • Genetic Factors (e.g., selective breeding, etc.)
  • Organisms
Students know:
  • Environmental factors can influence growth.
  • Genetic factors can influence growth.
  • Changes in the growth of organisms can occur as specific environmental and genetic factors change.
Students are able to:
  • Organize given data on how both environmental and genetic factors influence the growth of organisms to allow for analysis and interpretation.
  • Analyze the data to identify possible causal relationships between environmental and genetic factors and the growth of organisms.
  • Interpret patterns observed from the data to provide causal accounts for events and make predictions for events by constructing explanations.
Students understand that:
  • Genetic factors as well as local conditions affect the growth of organisms.
  • Because both environmental and genetic factors can influence organisms simultaneously, organism growth is the result of environmental and genetic factors working together.
  • Because organism growth can have several genetic and environmental causes, the contributions of specific causes or factors to organism growth can be described only using probability.
