The Underground Movement

This week at After School, girls applied the scientific method to the issue of pollution. Before beginning their experiments, students discussed how water moves underground. The groups hypothesized that different materials, such as sand and soil, would affect the movement of water and pollutants.

 

 

 

 

 

 

 

 

 

 

 

The girls created sand and soil filters, then watched as water polluted with dirt, dust, and food coloring made its way through the porous materials. Each girl wrote her observations next to her hypotheses. Finally, girls made a model of a well and poured polluted water in the sand and soil near the well opening. When the polluted water began to seep into the well, everyone agreed that it was very gross.

 

 

 

 

 

 

 

 

Pollution is icky and dangerous. At Girlstart we’re equipping future environmental scientists with the skills they need to improve our Earth’s precious resources!
