This activity can be completed at the end of studying the NGSS MS-ESS2-1 standard as an assessment. This type of assessment allows for learning to continue while students are creating their model. It requires students to create a model to describe the cycling of Earth’s materials and the flow of energy that drives this process.
Students are presented with an incomplete model. They then add needed elements to the model to meet the requirements of the standard. Students must show connections between cycles and answer essential questions.
