Think Garden: Soil Composition

This video explains why soil is more than just dirt. Learn how to tell if soil is rich and healthy or lacking in nutrients, which nutrients are essential, and what happens if plants lack these nutrients. Also find out how to improve soil, and find out what compost is, and how to use it.

Scientific Tools and Methods

Adapted from the Kentucky Life Biodiversity series, the videos in this interactive explore three examples of researchers applying the scientific method in various field situations.

Indicator Species: Hooded Warbler
