Who knew science teachers read story books in science class?!?






Note 1.2

Percolation Lab

· Normally, substances with the greatest percentage of air space between the particles would hold the most water.

· The most porous material, rock, had the largest spaces for water to pass through.

· The water drains into sand more slowly than into the gravel and into clay more slowly than into sand.

· Gravity causes groundwater to move downhill.

Capillary Lab

· Sand and soil with very small pores and spaces can hold water and transport water slowly through capillary action.

· Capillary action allows for groundwater to move uphill.
