Defining Gravity: Crash Course Kids #4.1

Defining Gravity: Crash Course Kids #4.1 So, if gravity pulls everything down, then why don't things on the bottom of the Earth get pulled down into space? In this episode of Crash Course Kids, Sabrina talks about gravity and explains that when we talk about gravity pulling things down, what we really mean is gravity is pulling things TOWARD the Earth. Really, it's all about attraction. This first series is based on 5th grade science. We're super excited and hope you enjoy Crash Course Kids! ///Standards Used in This Video/// 5-PS2-1. Support an argument that the gravitational force exerted by Earth on objects is directed down. [Clarification Statement: “Down” is a local description of the direction that points toward the center of the spherical Earth.] [Assessm...

Identifying where to reforest after wildfire

Identifying where to reforest after wildfireIn the aftermath of megafires that devastated forests of the western United States, attention turns to whether forests will regenerate on their own or not. Forest managers can now look to a newly enhanced, predictive mapping tool to learn where forests are likely to regenerate on their own and where replanting efforts may be beneficial. The tool is described in a study published in the journal Ecological Applications by researchers from the University of California, Davis; U.S. Geological Survey (USGS), Cal Fire and the U.S. Forest Service. "Huge fires are converting forested areas to landscapes devoid of living trees," said lead author Joseph Stewart, a postdoctoral researcher at UC Davis and with USGS. "Managers need timely and accurate informa...
