Moisture—Student Laboratory Kit
Do all types of soil hold the same amount of water? How much more water can one soil hold than another? Students perform three easy-to-follow lab activities to determine how pore size, soil texture, compaction and surface runoff are affected.

Demonstrate the ability of soil to bind and store essential nutrients and exchange them with plants by filtering dye solutions through soil and sand. It also provides a nice visual aid to tie in larger environmental themes, such as the ability of soil to process “chem- ical waste” and protect against runoff and groundwater contamination.

Soil is a complex mixture of inorganic miner- als, organic matter, air and water. The size
of the particles in soil affects not only how much air is present but also the ability of soil to hold water. In this kit, students deter- mine the permeability and porosity of soil by measuring how easily air and water move through soil and the volume of air and water the soil will hold.

Porosity and Permeability—
Column Kit with Bead Set
How does porosity and permeability affect groundwater aquifers? Students, through experimentation, will learn about pore size, permeability and particle size. Help students learn these important concepts and integrate math, measurement and percentage skills. AP6434 I $76.35
Groundwater Exploration Activity Model
Your students will learn about the sources of groundwater, its storage and flow beneath the Earth’s surface and how this unseen resource impacts life at the Earth’s surface. They’ll use dyes as simulated contaminants to reveal how groundwater can become polluted and how its contamination can directly affect the environment.
