Question
They were concerned about toxins and other chemicals flowing into the aquifer. They hoped to simulate this happening in their model. They brainstormed and came up with several ideas that would help simulate the movement of toxins into their aquifer. Which scenario is the most likely?

A The students rebuilt the model with a layer of soil below the rock layer. They added brown dye directly to the groundwater to observe how it moved into the soils.The students rebuilt the model with a layer of soil below the rock layer.

B The students added dirt to the top of the hill in the model.They sprinkled water over the dirt to see if the dirt moved downhill into the area that represented groundwater.The students added dirt to the top of the hill in the model.They sprinkled water over the dirt to see if the dirt moved downhill into the area that represented groundwater.
C The students added some green grass and sprinkled the grass with some brown dye. They used the dye to represent the fertilizer.

The most likely scenario for simulating the movement of toxins into an aquifer would be:
**D**: The students added some brown dye to the water that they were pouring into the modeled aquifer. The dye represented the fertilizer that drains into the aquifer. They watched to see if the dye collected in the rock layer.
This scenario directly simulates the process of contaminants (represented by the dye) entering the aquifer through water movement, which is relevant to understanding how toxins can affect groundwater. It effectively models the potential pathways of pollutants from surface sources into the aquifer system.
