ETA

This page features the ETA protocol aligned to the Ohio Science Standards:  

Ohio Model Curriculum – Physical Geology

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.

Earth’s History

 

The geologic rock record

 

Relative and absolute age

 

Principles to determine relative age

  • Original horizontality

  • Superposition

  • Cross-cutting relationships

Absolute age

  • Radiometric dating (isotopes, radioactive decay)

  • Correct uses of radiometric dating

 

Combining relative and absolute age data

 

The geologic time scale

  • Comprehending geologic time

    • Climate changes evident through the rock record

  • Fossil record

 

Plate Tectonics

 

Internal Earth

Seismic waves

  • S and P waves

  • Velocities, reflection, refraction of waves

Structure of Earth (Note: specific layers were part of grade 8)

  • Asthenosphere

  • Lithosphere

  • Mohorovicic boundary (Moho)

  • Composition of each of the layers of Earth

  • Gravity, magnetism and isostasy

  • Thermal energy (geothermal gradient and heat flow)

Historical review (Note: this would include a review of continental drift and sea-floor spreading found in grade 8)

 
  • Paleomagnetism and magnetic anomalies

  • Paleoclimatology

 

Plate motion (Note: introduced in grade 8)

 
  • Causes and evidence of plate motion

  • Measuring plate motion

  • Characteristics of oceanic and continental plates

  • Relationship of plate movement and geologic events and features

  • Mantle plumes

 

Earth’s Resources

 

Energy resources

  • Renewable and nonrenewable energy sources and efficiency

  • Alternate energy sources and efficiency

  • Resource availability

  • Mining and resource extraction

 

Air and Air pollution

a. Primary and secondary contaminants

b. Greenhouse gases

c. Clean Air Act

d. Point source and nonpoint source contamination

Students will be observing canopy cover and can measure the amount of CO2 gases surrounding the area. The students can also research the Clean Air act and consider that while renovating the trees.

Glacial Geology

Glaciers and glaciation

  • Evidence of past glaciers (including features formed through erosion or deposition)

  • Glacial deposition and erosion (including features formed through erosion or deposition)

  • Data from ice cores

  • Historical changes (glacial ages, amounts, locations, particulate matter, correlation to fossil evidence)

  • Evidence of climate changes throughout Earth’s history

  • Glacial distribution and causes of glaciation

  • Types of glaciers – continental (ice sheets, ice caps), alpine/valley (piedmont, valley,

cirque, ice caps)

  • Glacial structure, formation and movement
