Lesson 2 : Lab
Time Required: 200 minutes
- Participate in a Biodiversity Nature Walk in order to identify organisms inhabiting the schoolyard ecosystem.
- Diagram how organisms are connected to one another within the schoolyard ecosystem.
- Roll the “Dice of Destiny” to encounter an environmental stressor and predict how the environmental stressor could impact on the biodiversity within the schoolyard ecosystem.
- Create a final split-poster to show schoolyard biodiversity and organism connections before and after the environmental stressor.
Standards
- MS-ETS1-1
- Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
- MS-LS2-4
- Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations. [Clarification Statement: Emphasis is on recognizing patterns in data and making warranted inferences about changes in populations, and on evaluating empirical evidence supporting arguments about changes to ecosystems.]
- 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.]
