Grade 6 Lesson plan
The Dunmere Aquifer Model: Porosity and Groundwater Storage
A 50-minute grade 6 science lesson where students model an aquifer with gravel and sand, then calculate porosity to explain why some ground stores groundwater well.
NGSS · Middle School (6–8)
Construct a scientific explanation based on evidence for how the uneven distributions of Earth's mineral, energy, and groundwater resources are the result of past and current geoscience processes.
Clarification statement: Emphasis is on how these resources are limited and typically non-renewable, and how their distributions are significantly changing as a result of removal by humans. Examples of uneven distributions of resources as a result of past processes include but are not limited to petroleum (locations of the burial of organic marine sediments and subsequent geologic traps), metal ores (locations of past volcanic and hydrothermal activity associated with subduction zones), and soil (locations of active weathering and/or deposition of rock).
Why water teaches this standard well
Groundwater is named directly in this performance expectation, making it a natural home for aquifer lessons. Students can explain why some regions sit atop vast aquifers while others have little, and why heavy pumping, as in the Ogallala, is drawing down a resource that recharges only slowly.
Materials tagged with this code are written to the full standard , including its clarification statement , and each carries a written note explaining the alignment. See how we review materials.
