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?"
