Brooks River Brown Bears: Inheritance and Variation of Traits

Standards and Objectives

OBJECTIVES

Lesson 1

Understand the difference between inherited and acquired traits.

Lesson 2

Recognize that bears’ fishing techniques are learned, acquired behaviors that can be used as distinguishing traits.

Lesson 3

Identify brown bears based on their inherited and acquired traits.

3-LS3-1 Heredity: Inheritance and Variation of Traits
  • Analyze and interpret data to provide evidence that plants and animals have traits inherited from parents and that variation of these traits exists in a group of similar organisms.
3-LS3-2 Heredity: Inheritance and Variation of Traits
  • Use evidence to support the explanation that traits can be influenced by the environment.
Science and Engineering Practice 1Asking Questions and Defining Problems
  • Identify scientific (testable) and non-scientific (non-testable) questions.
  • Ask questions that can be investigated and predict reasonable outcomes based on patterns.
Science and Engineering Practice 4Analyzing and Interpreting Data
  • Represent data in tables to reveal patterns that indicate relationships.
  • Analyze and interpret data to make sense of phenomena.
Science and Engineering Practice 8Obtaining, Evaluating, and Communicating Information
  • Obtain and combine information from reliable media to explain phenomena.
Disciplinary Core Idea LS3.AInheritance of Traits
  • Many characteristics of organisms are inherited from their parents.
  • Other characteristics result from individuals’ interactions with the environment, which can range from diet to learning. Many characteristics involve both inheritance and environment.
Disciplinary Core Idea LS3.BVariation of Traits
  • Different organisms vary in how they look and function because they have different inherited information.
  • The environment also affects the traits that an organism develops.
Crosscutting Concept 1Patterns
  • Observed patterns of forms and events guide organization and classification, and they prompt questions about relationships and the factors that influence them.

Texas Essential Knowledge and Skills
Grade 3, Science, 3.4Scientific Investigation and Reasoning
  • The student knows how to use a variety of tools and methods to conduct science inquiry. The student is expected to collect, record, and analyze information using tools, including cameras, computers [...] and materials to support observation of habitats of organisms such as terrariums and aquariums.
Grade 4, Science, 4.4Scientific Investigation and Reasoning
  • The student knows how to use a variety of tools, materials, equipment, and models to conduct science inquiry. The student is expected to collect, record, and analyze information using tools, including [...] cameras, computers, [...] and materials to support observation of habitats of organisms such as terrariums and aquariums.
Grade 4, Science, 4.10.BOrganisms and Environments
  • The student is expected to explore and describe examples of traits that are inherited from parents to offspring such as eye color and shapes of leaves and behaviors that are learned such as reading a book and a wolf pack teaching their pups to hunt effectively.
Grace 5, Science, 5.10.BOrganisms and Environments
  • The student is expected to differentiate between inherited traits of plants and animals such as spines on a cactus or shape of a beak and learned behaviors such as an animal learning tricks or a child riding a bicycle.

Florida Next Generation Sunshine State Standards for Science
Grade 4, SC.4.L.16.2Explain that although characteristics of plants and animals are inherited, some characteristics can be affected by the environment.
Grade 4, SC.4.L.16.3Recognize that animal behaviors may be shaped by heredity and learning.
