In All About Solids, Liquids & Gases, young students will be introduced to the three common forms of matter. They’ll learn that all things are made up of tiny particles called atoms and that the movement of these particles determines the form that matter takes. In solids, the particles are packed tightly together and move very little. The particles in liquids are more spread out and move faster. In a gas, the particles are spread even farther apart and move even faster.
Chemistry is a subject that many students approach with dread. With Chemistry Success there's no reason to fear. This friendly, straightforward guide uses a series of simple 20-step lesson plans to teach students what they need to quickly grasp the essentials of this subject. • Covers all key chemistry topics, from measurement and matter, to molecules, compounds, and chemical change, to energy, electrons, gases, liquids, solids, and solutions • Includes exercises in test format, tips on taking standardized tests, vital resources, and a glossary
While there are several factors that contribute to global warming, such as natural changes in the Earth's inclination and revolution around the sun, by far the biggest factor is the emission of greenhouse gases. Carbon dioxide, methane, ozone, chlorofluorocarbons, water vapor, and nitrous oxide are added at alarming rates to the atmosphere by daily human activity. Every person on Earth has a 'carbon footprint' - a measure of greenhouse gas contributed to the atmosphere on a daily basis.
Disney Educational - Bill Nye The Science Guy: Phases of Matter
The three phases of matter get the Bill Nye treatment in this program. As usual, although some of the science concepts explored in the programs can be complex, Nye is in tune with what students are capable of understanding and uses humor to create a fun learning atmosphere. In this episode, he discusses the finer points of solids, liquids, and gases, using examples that kids can relate to. The idea of frying an ice cube is presented to help illustrate what matter is all about.
Earth's atmosphere supports and protects all of its life, giving the planet its blue skies, mild temperatures, and weather. But people use the atmosphere for another purpose: as a dump for waste gases and particles. Air pollution obscures vistas, damages ecosystems, and compromises human health. Combined with water in the atmosphere, air pollutants create acid rain. In the upper atmosphere, air pollutants damage the ozone layer, which protects life from the sun's harmful rays. Excess emissions of greenhouse gases like carbon dioxide and methane push global temperatures higher, creating global warming. While some pollutants are successfully regulated, as population grows and industries expand, more intensive solutions are needed to deal with the many types of air pollution and its consequences. This provocative book tackles these issues in a straightforward manner and shows readers what they can do to help conserve our planet's atmosphere.
