Connecticut Content Standard 6: Cycles Of Life

Students will recognize patterns and products of genetics and evolution.


Grades K - 4


Educational experiences in Grades K - 4 will assure that students:

  • identify (in Grades K-2) external features of organisms that help them survive in different kinds of places;
  • understand (in Grades K-2) that offspring tend to resemble their parents and that individuals of the same species have variations;
  • recognize (in Grades K-2) that some organisms are alike in the way they look and in the things they do, and others are very different from one another;
  • recognize (in Grades K-2) that many organisms once living on the Earth have disappeared;
  • understand that organisms that are alive on the Earth today are both similar to and different from organisms that have disappeared;
  • understand that, when living things reproduce, they transfer genetic information from one generation to the next;
  • recognize that individuals of the same species differ in their characteristics, and sometimes these differences give individuals an advantage in surviving and reproducing; and
  • describe the life cycle of familiar organisms (e.g., frog, butterfly, cat, dandelion).

Grades 5 - 8

Educational experiences in Grades 5 - 8 will assure that students:

  • understand that each organism carries a set of instructions (genes) for specifying the components and functions of the organism;
  • explain that differences between parents and offspring can accumulate in successive generations so that descendants are very different from their ancestors;
  • recognize that individual organisms with certain traits are more likely than others to survive and have offspring;
  • understand that the extinction of a species occurs when the environment changes and the species is not able to adapt to the changes;
  • understand that the basic idea of biological evolution is that the Earth’s present-day species developed from earlier species; and
  • know that the many thousands of layers of sedimentary rock provide evidence for the history of the Earth and its changing life forms.

Grades 9 - 12

Educational experiences in Grades 9 - 12 will assure that students:

  • recognize that changes in the types of species on Earth may have occurred either gradually or through sudden bursts of major change (punctuated equilibrium);
  • compare and contrast Mendel’s laws (segregation and independent assortment) of heredity;
  • understand how fossil, anatomical, molecular and other observable forms of evidence provide support for the theory of natural selection;
  • explain that preservation of the Earth’s biological diversity is critical to the future of human beings and other living things;
  • describe scientific theories for the origin of life and the evidence to support the theories;
  • explain the differences between human beings and other primates;
  • describe the biological history of human beings;
  • compare and contrast different types of asexual and sexual reproduction;
  • explain how new heritable characteristics can result from new combinations of existing genes or from mutations of genes in reproductive cells; and
  • understand that modern molecular biology allows scientists to analyze, isolate and alter genes, and this ability helps scientists in the analysis and treatment of certain diseases.
