Chemistry - Annenburg Foundation Unit Overview Since the first time early humans lit a fire, cooked food, fermented fruit, or flaked a stone axe, we have been manipulating the matter around us. This unit explores how chemistry evolved from adapting materials for practical purposes to a science that systematically offers solutions to the world's challenges. It is a story that will start with Democritus around 400 BCE, taking us through the early Arab chemist, Jābir ibn Hayyān, to the meticulous work of the Middle Age alchemists, and finally to the birth of chemistry as a science during the Age of Enlightenment in the 18th century. In the accompanying video, we explore the Silicon Age, where the goal of manipulating and purifying matter at the atomic scale is making possible today's technological advances such as cell phones and solar panels.

Herd Instinct in Horses Herd Instinct Horses are social herd animals that follow a leader and conform to a dominance hierarchy. For their own safety they choose to be a part of a group of horses such as a band or a herd. A horse is a grazing animal, never a predator and always the prey. kamal Wafi 1 General Physics (IGCSE) Play all These videos will hopefully eventually cover all of the topics for IGCSE international GCSE in the Cambridge syllabus labelled general physics. 15:03 5:09 9:20 8:00 6:22 9:54 This item has been hidden This item has been hidden This item has been hidden This item has been hidden This item has been hidden This item has been hidden This item has been hidden

Virtual Labs The Virtual Lab is an online simulation of a chemistry lab. It is designed to help students link chemical computations with authentic laboratory chemistry. The lab allows students to select from hundreds of standard reagents (aqueous) and manipulate them in a manner resembling a real lab. Nonrenewable and Renewable Energy Resources : QUEST There are nine major areas of energy resources. They fall into two categories: nonrenewable and renewable. Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. This is usually due to the long time it takes for them to be replenished. Renewable resources are replenished naturally and over relatively short periods of time. The five major renewable energy resources are solar, wind, water (hydro), biomass, and geothermal.
