Module: Changes in Biodiversity
DCI: LS2.D (0) Changes in biodiversity can influence humans’
resources, such as food, energy, and medicines, as well as ecosystem services
that humans rely on – for example, water purification and recycling.
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 factors such 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.
DCI: ETS1.B: There are systematic processes for evaluating
solutions with respect to how well they meet the criteria and constraints of a
problem.
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.]
So the bottom line is that when the biodiversity in an ecosystem changes, it has an effect on the resources humans depend on. This will be a fairly easy topic to write very general questions on. We could provide a list of resources, their source, and their use. Then, we could ask, which of the following uses (related to the resource) would be most threatened by (a specific threat to biodiversity).
Possible Question Starters:
"Changes to an ecosystem's biodiversity can have a direct affect on humans because -"
correct answer - humans depend on many natural resources
incorrect answer -
