In this classroom activity, students will show how soil composition affects the amount of water the soil holds. They will test sand and soil independently and then create their own mixture.

As a citizen scientist, students use a soil test kit to find out how much of each type of chemical is in the local soil.

Compare soil composition from different regions of the Earth, including the Galapagos Islands, and perform analysis of three important macronutrients found in regional soil.

For this activity, young scholars test the percolation rates of water passing through different soil compositions.

Students investigate the critical nature of foundations as they learn differences between shallow and deep foundations, including the concepts of bearing pressure and settlement. Using models representing a shallow foundation and a deep...

Students conduct an experiment to determine how varying the composition of a construction material affects its strength. They make several adobe bricks with differing percentages of sand, soil, fibrous material and water. They test the...
