Overview:

Through videos and sorting exercises, this lesson delves into the fascinating process and products of sexual selection: the process by which traits become more or less common depending on an individual’s ability to mate with more or better partners.

10 ) Use evidence and scientific reasoning to explain how characteristic animal behaviors (e.g., building nests to protect young from cold, herding to protect young from predators, attracting mates for breeding by producing special sounds and displaying colorful plumage, transferring pollen or seeds to create conditions for seed germination and growth) and specialized plant structures (e.g., flower brightness, nectar, and odor attracting birds that transfer pollen; hard outer shells on seeds providing protection prior to germination) affect the probability of successful reproduction of both animals and plants.

Evidence Of Student Attainment:
Students:
  • Make a claim to support a given explanation including the idea that characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants respectively.
Teacher Vocabulary:
  • Evidence
  • Cause and effect
  • Scientific Reasoning
  • Characteristics
  • Behaviors
  • Specialization
  • Probability
  • Reproduction
  • Validity
  • Reliability
  • Relevance
Knowledge:
Students know:
  • Animals engage in characteristic behaviors that increase the odds of reproduction.
  • Plants reproduce in a variety of ways, sometimes depending on animal behavior and specialized features for reproduction.
Skills:
Students are able to:
  • Make a claim to support a given explanation of a phenomenon, including the idea that characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants respectively.
  • dentify the given evidence that supports the claim (e.g., evidence from data and scientific literature).
  • Evaluate the evidence and identify the strengths and weaknesses of the evidence used to support the claim.
  • Use reasoning to connect the appropriate evidence to the claim, using oral or written arguments.
Understanding:
Students understand that:
  • Many characteristics and behaviors of animals and plants increase the likelihood of successful reproduction.
  • Animal behavior plays a role in the likelihood of successful reproduction in plants.
  • Because successful reproduction has several causes and contributing factors, the cause and effect relationships between any of these characteristics and reproductive likelihood can be accurately reflected only in terms of probability.
