This page features the alignment of the ETA protocol to the Ohio science standards  

Ohio Model Curriculum – Biology

Alignment with ETA Protocol


1)  Overall Goals


• Know, use and interpret scientific explanations of the natural world;

-Hydrology, habitat alteration and development, and plant communities all relate to the creation of habitat for living organisms.

-The better outcome from the survey, the more money the community will is worth as far as trees goes which is related to habitat improving biodiversity


• Generate and evaluate scientific evidence and explanations, distinguishing science from pseudoscience

-The ETA metric allows a community to see how much money it will provide based on the tree survey

-The ETA can also display a map of the trees that have been surveyed, which includes the species, diameter, GPS location, and any maintenance that is required


• Understand the nature and development of scientific knowledge;

-The ETA allows the students to understand that scientific knowledge is constantly changing and improving.

• Participate productively in scientific practices and discourse.

- Students learn about common scientific protocols, metrics and how they are used to compare results gathered by anyone using the protocol.

- Students see how to interpret their results in light of the results gathered by others using the same protocols increasing discourse among scientists

2) Specific Curricular Goals

Science Inquiry and Application

• Identify questions and concepts that guide scientific investigations;

-Students determine the quality of tree in its environment  based on observations and questions from the app. They identify questions and concepts that link biological findings to the physical environment, i.e. Is the bark damaged? What condition are the leaves in?


• Design and conduct scientific investigations;

- Students observe trees, and hypothesize the hydrology, habitat alteration and development, and plant communities present in the urban tree distribution. They follow a standardized protocol to gather data and score the trees through a mobile web app.


• Use technology and mathematics to improve investigations and communications;

-The use of smartphones and tablets in completing ETA will allow the students to use technology to improve their learning.

• Formulate and revise explanations and models using logic and evidence (critical thinking);

- Results can be compared with other trees and other sites in surrounding areas

- Results are used to determine the best place to sight future development and to conserve habitat.


• Recognize and analyze explanations and models; and

-Students relate habitat to the biology of organisms determining why specific habitats support organisms that are more sensitive to changes in high quality environments

• Communicate and support a scientific argument.

- Students use their own data to determine the quality of the tree they observed.

Course Content

  • Heredity

    • Cellular genetics

    • Structure and Function of DNA cells

    • Genetic mechanisms and inheritance

    • Mutations

    • Modern genetics

    • Students can study genetic variations between the same species of trees. They could look at mutations that are affecting the trees. They could disucss the role of some organelles and the processes they are involved in.

  • Evolution

    • Natural Selection

    • Mutation

    • Genetic drift

    • Gene Flow

    • Diversity of Life

    • Students can examine the diversity of trees on their campus and see how genetics has changed from tree to tree.

  • Diversity and Interdependence of Life

    • Diversity of Life Ecosystems

    • Homeostasis

    • Carrying Capacity

    • Classification Systems are Frameworks created by scientists for describing the vast diversity of organisms indicating the degree of relatedness between organisms

    • Students can examine the role trees have in the environemnt, and see how they relate to other organisms in the ecosystem.

  • Cells

    • Cells structure and function

    • Cellular process

    • Students can examine the role organelles have in trees and what cellular processes they are involved in.
