NGSS MS LS2 Ecosystem Assessments: This resource is a set of assessments that cover the LS2 standards for Middle School Science for the DCI LS2 Interactions, Energy, and Dynamics. These assessments are multiple-choice and short-answer. You can use them after each standard is taught to assess the students or at the end of the year to review and assess. Answer Keys are included. This resource includes both a printable resource and five Google forms (one for each standard).
Covers the following standards:
NGSS MS LS Interactions, Energy, and Dynamics
NGSS MS- LS2-1 Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.
NGSS MS-LS2-2 Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.
NGSS MS LS 2.3 Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
NGSS MS LS 2.4 Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
Evaluate competing design solutions for maintaining biodiversity and ecosystem services.
The study of ecosystems includes the interaction of organisms with each other and with the physical environment. Consistent interactions occur within and between species in various ecosystems as organisms obtain resources, change the environment, and are affected by the environment. This influences the flow of energy through an ecosystem, resulting in system variations. Additionally, ecosystems benefit humans through processes and resources, such as the production of food, water, and air purification, and recreation opportunities. Scientists and engineers investigate interactions among organisms and evaluate design solutions to preserve biodiversity and ecosystem resources.
