Reproduction is the third unit to be released from the Issues and Science, Third Edition from SEPUP at the Lawrence Hall of Science, University of California, Berkley. 

It is a 3-4 week middle school unit that focuses on the ethical issues involved in using genetic information. Reproduction is fully aligned to the three dimensions of the NGSS and bundles the following Performance Expectations: 

  • Performance Expectation MS-LS1-4: Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants, respectively.
  • Performance Expectation MS-LS1-5: Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms.
  • Performance Expectation MS-LS3-1: Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of an organism.
  • Performance Expectation MS-LS3-2: Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.
