Comment on this resource
The purpose of this resource is to introduce the different particle sizes of soils and the properties which each contributes to the soil character. Students make mud pies by adding water to the various soil components, letting them dry and observing the pie's characteristics. Students sift soil to remove organic materials and pebbles. They then sift the soil with smaller meshed sieves to separate ... Full description.

Comment on this resource
The purpose of this resource is to develop an understanding of some of the relationships between soils of different types and water. Students will time the flow of water through soils with different properties and measure the amount of water held in these soils. They will also experiment with the filtering ability of soils by testing the pH of the water before and after it passes through the soil ... Full description.

The purpose of this resource is to measure the pH of a soil horizon. Students mix dried and sieved soil samples with distilled water. The mixture is allowed to settle until a relatively clear layer is formed. Students use a pH pen, pH meter, or pH paper to determine the pH of the sample. The procedure is done three times for each horizon. Full description.

The purpose of this resource is to recognize patterns of green-up at the plant, landscape and regional scales. This activity is to prepare students to recognize what a bud looks like and the progression of green-up from the time of budburst. Students will arrange plant growth pictures taken from the bud, shrub canopy, grass clump, landscape and regional perspectives. Full description.

Comment on this resource
The purpose of this resource is to understand that soil, under different environmental conditions, plays a role in the decomposition of organic materials. Students use bottle experiments to observe changes in the decomposition of vegetable scraps. Students vary temperature, moisture, and light conditions to determine the conditions that best facilitate the decomposition of organic material in soil. ... Full description.
