Grade 4 4-3

Page history last edited by Pam Merrill 3 years, 10 months ago

Oklahoma Academic Standard 4. The student will identify basic economic activities of the United States. 

Objective 4.3 Explain how economic activities can threaten the physical environment.
A.  Identify ways in which humans can change ecosystems, such as clearing forests, draining wetlands, and diverting waterways, by examining present-day issues related to the use of resources.

B.  Identify examples of changes in land use in local communities and how the physical environment can be stressed by human activities.

In a Nutshell

Students should understand how human decisions to alter their environment can result in significant changes to ecosystems, some of which are highly beneficial and needed for human development, while others may be detrimental to the natural environment or a future threat to quality of life. Students should begin to examine the fact that human actions have both short-term and long term consequences which can be mitigated by careful planning and management of available resources.

Teacher Action 

Student Action 

  • Assist students to answer geographic questions by organizing geographic information about regions of the United States from historical as well as contemporary perspectives, including how  geographic features have been modified for human use.

  • Provide opportunities for students to explain how economic actions can influence the ways people modify and adapt to their environment and how those actions can positively or negatively impact ecosystems.

  • Assist students to clearly state an opinion through written products, supported by commentary including examples, details, and reasoning. 

  • Explain multiple causes and effects of events and developments of the past or present.

  • Gather, compare, and analyze information between primary and secondary sources about the past and present. 

  • Engage in collaborative discussions regarding responsibilities of individuals and communities to reduce stress on their physical environments.

  • Explain the challenges people have faced and the strategies used to address local, regional, or national historical problems.

  • Compose informative essays and written products by introducing and developing a topic, incorporating evidence (e.g. facts, examples, details) related to historic or contemporary examples of human-environment-interaction.
