Standard 5
Students will understand that biological diversity is a result of evolutionary processes.
Objective 3
Classify organisms into a hierarchy of groups based on similarities that reflect their evolutionary relationships.
  • Classifying Fruit
    Students will classify fruit from pictures, using a scientific key, and by dissection of a real fruit. They will connect what they have learned to reading from their textbooks.
  • Ecosystem Survey Using Classification and Plant ID
    Scientists use many tools to evaluate the health of a habitat. One way to classify and determine the health of a habitat is to identify the organisms that live there and compare those to other habitats. To do this biologists use identification keys. In this exercise students will use identification keys to identify plants in various habitats and determine adaptations for success / evolution of different species.
  • Evolutionary Timelines
    In this activity students will build timelines of the history of life in the universe. The timelines are built to scale to help students visually see how life has developed over time.
  • Making Student Collections
    Students will gain an understanding of classification systems and find application of science to the world they come in contact with each day by creating their own collections.
  • Tree Key
    In this activity students will use a dichotomous key to identify native Utah conifers
