Soil Stories

Class members analyze the water content in soil samples by drying out the samples and taking measurements every minute until all the moisture is gone. Scholars compare the initial weight to the dried weight to calculate the percentage of...

Do great gardeners really have green thumbs—or just really great soil? Environmental scholars discover what makes Earth's soil and soil quality so important through research and experimentation. Learners also develop an understanding of...

Here is an all-encompassing overview of the plant kingdom! In this learning exercise, beginning botanists describe characteristics of the four different plant phyla, explain various life cycles, differentiate between monocots and dicots,...

The ups and downs of plant vascular tissue are described by your beginning botanists as they complete this worksheet. Xylem and phloem are defined and identified on actual color photographs. Functions of the different types of meristem...

Is it true that larger animals have longer lifespans than smaller animals? Does an animal's habitat help shape the length of its life? And does the ability to adapt and evolve allow living things to expand their lifespans? Watch a...

Young scientists learn the importance of knowing blood types and their compatibility. The instructor in the video explains each type of blood and their antigens and antibodies, and then differentiates between AB blood and Rh blood...

All mammals have warm blood, are vertebrates, breathe with their lungs, have hair or fur on their bodies, and produce milk for their young. But not all mammals give birth to their young in the same manner. Watch a video that explains how...

Here is a fascinating video that explores the genetic implications of our blood types as humans, how we can determine an individual's blood type based on cell alleles, the RH factor, and how blood types can mean life or death for those...

Some scientists spend their entire careers analyzing and learning about soils. An interesting video lesson provides an overview of what soil scientists do and why. Pupils learn how soil analysis connects to other branches of science...

Soil pollution has a longer reach than may seem possible. A video presentation demonstrates how a seemingly isolated soil contamination spreads and even reaches waterways. The lesson demonstrates how scientists conduct porosity tests...
