8.E.1:  Understand the hydrosphere and the impact of humans on local systems and the effects of the hydrosphere on humans.
Essential Understanding:  The hydrosphere affects humans and humans affect the hydrosphere.
Essential Questions:  What is the structure  and function of the hydrosphere?
                                How does the hydrosphere affect humans?
                                How do humans; affect the hydrosphere


8E1.1:  Explain the structure of the hydrosphere including:
  •         Water distribution on Earth
  •         local river basins and water availability

Essential Understanding:  The students will understand:
  •             that the water is one of the most common substances on the surface of the Earth
  •            that the ocean is an integral component of the world's climate due to its capacity to collect, drive and mix water, heat, and carbon       dioxide.
  •         that the water cycle is the continuous movement of water in and around the Earth.
  •         that a river basin is the portion of land drained by a river and its tributaries
  •         that for land-dwellers, everyone lives in a river basin

Essential Questions:
  •           how do factors interact to determine the distribution of water in the hydrosphere?
  •         How does the water cycle affect water distribution on Earth?
  •         Hoe do river basins affect availability?

8.E.1.2:  Summarize evidence that Earth's oceans are a reservoir of nutrients, minerals, dissolved gases, an  life forms:  estuaries, marine ecosystems, upwelling, and behavior of gases in the marine environment, and deep ocean technology and understandings gained.

Essential Understandings:  The students will understand:
  •             That the ocean is a dynamic system in which many chemical, biological, and physical changes are taking place.
  •             That estuaries are areas where fresh and salt water mix, producing variations in salinity and high biological activity
  •             That from the seashore to the deepest depths, oceans are hoe to some of the most diverse life on Earth
  •             That in the ocean there are innumerable individual food chains overlapping and intersecting to form complex food webs.
  •             How winds have a powerful effect on the oceans and are an important force in creating ocean currents
  •               That seawater has many different gases dissolved in it, especially nitrogen, oxygen and carbon dioxide
  •             That carbon dioxide is one the most important gases that dissolve in the ocean.
  •             That the ocean is one of Earth's most valuable natural resources
Essential Questions: 


  •                 How do we know what the oceans are made of?
  •                 How do Earth's oceans affect other ecosystems?


8.E.1.3: Predict the safety and potability of water supplies in North Carolina based on physical and biological factors, including:  temperature, dissolved oxygen, pH, nitrates and phosphates, turbidity, bio-indicators.

Essential Understanding:  The student will understand:
  •             That the health of a water system in determined by the balance between physical, chemical and biological variables
  •             That the temperature of water in rivers and lakes determines the kinds of organisms that can survive there.
  •             That measuring dissolved oxygen is an important factor in determining water quality
  •             That pH is a measure of how acidic or basic water is
  •             That nitrogen and phosphorous are essential plant nutrients
  •             That turbidity is a measure of how clear water is.
  •             That the water quality of a body of water can also be assessed by using bio indicators (macro invertebrates)

Essential Questions: 
  •             How safe and drinkable is the water around North Carolina?
  •             How are physical and biological factors used to determine the quality of water?
8.E.1.4:  conclude that the good health of humans requires:
            Monitoring of the hydrosphere
            Water quality standards
            Methods of water treatment
            Maintaining safe water quality
            Stewardship

Essential Understandings:  The students will understand:
  •         That water quality is a term used to describe the chemical, physical, and biological characteristics of water
  •         That water quality standards outline the water quality pollution control program that is mandated and regulated by local, regional and federal agencies
  •         Clear water many contain odorless, tasteless, and colorless harmful contaminants
          That water is essential to life

Essential Questions:
  •             What can we do to protect our water supply?
8.L.3: Understand how organisms interact with and respond to the biotic and abiotic component of their environment.
Essential Understanding:  the students will understand:
Living things and non living things in and environment can affect organisms.

 
Essential Questions:
1)  How do living things obtain and use energy?
2)  How do organisms survive in harsh or changing environments?


8.L.3.1:  Explain how factors such as food, water, shelter, and space affect population in an ecosystem.

Essential Understandings:   The students will understand that:
  • ecosystems are complex, interactive systems that include both biological communities (biotic) and physical (abiotic) components of the environment
  • ecosystems are dynamic in nature; their characteristics can vary over time.
  • a population is a group of organisms belonging to the same species that live in a particular area
  • population density measures the number of individual organisms living in a defined space.

Essential Questions:
  1. How do factors such as food, water, shelter and space affect population in an ecosystem?
  1. How do these factors interact to affect populations in an ecosystem?
8.L.3.2:  Summarize teh relationship among producers, consumers, and decomposers including the positive and negative consequences of such interaction including:
  • coexistence and cooperation
  • competition
  • parasitism
  • mutualism

Essential Understandings:  The students will understand:
  • that organisms in an ecosystem constantly interact
  • that an ecosystem is defined as a community (all the organisms in a given area) and the abiotic factors (such as water, soil, or climate) that affect them.
  • that in any ecosystem, organisms and population with similar requirements for food, water, oxygen, or other resources may compete with each other for limited resources.

Essential Question:
  1. How and why do organisms interact with one another?


8.L.3.3: Explain how the flow of energy within food webs is interconnected with the cycling of matte (including water, nitrogen, carbon dioxide and oxygen) 

Essential Understandings:  The students will understand that:
  • the sun is the ultimate source of energy
  • food provides molecules that serve as fuel and building material for all organisms
  • over a long time, matter is transferred fro one organism to another repeatedly and between organisms and their physical environment
  • the flow of energy through ecosystems can be described and illustrated in food chains, food webs and  pyramids (energy, number, and biomass)
  • the flow of energy is interconnected with the cycling of matter

Essential Questions:
  1. How do food webs model the distribution of energy in an ecosystem?
  1. In what ways do matter and energy connect?
