MS - LS3.C (B) - Ecosystem Diversity - FINAL (WND)

Module: Ecosystem Biodiversity
DCI: LS2.C (B) Biodiversity describes the variety of species found in Earth’s terrestrial and oceanic ecosystems. The completeness or integrity of an ecosystem’s biodiversity is often used as a measure of its health.
Connections to Engineering, Technology, and Application of Science: Influence of Science, Engineering, and Technology on Society and the Natural World: The use of technologies and any limitations on their use are driven by individual or societal needs, desires, and values; by the findings of scientific research; and by differences in such factors as climate, natural resources, and economic conditions. Thus technology use varies from region to region and over time.
Connections to Nature of Science: Science Addresses Questions About the Natural and Material World: Science knowledge can describe consequences of actions but does not make the decisions that society takes.

 PE: MS-LS2-5 Evaluate competing design solutions for maintaining biodiversity and ecosystem services.

 [Clarification Statement: Examples of ecosystem services could include water purification, nutrient recycling, and prevention of soil erosion. Examples of design solution constraints could include scientific, economic, and social considerations.]

The ideas in this standard are: 
- biodiversity is the variety of species found in ecosystems
- the biodiversity of an ecosystem can be used as a way to assess its overall health. 

Possible Question Starters
"An increase in which of the following factors of an ecosystem would most likely increase its biodiversity?"
