EARTH SCIENCE  LEARNING OBJECTIVES: At the of the discussion the learners are expected to: MELC : ( S11ES-1a-b-3) Know the characteristics of the Earth; Recognize the difference in characteristics between the Earth and its neighboring planets; Identify factors that allow planet to support life ; and Craft a slogan showing your care to all life forms in the planet. It presents the history of the Earth through geologic time. It discusses the Earth's structure and composition, the processes that occur EARTH beneath and on the Earth's SCIENCE surface, as well as issues, concerns, and problems pertaining to Earth's resources. MODULE 1:  ?

In this range, liquid water can still exist under certain condition.  EARTH’S ATMOSPHERE Earth and Venus are the right size to hold a sufficient-sized atmosphere. Earth’s atmosphere is about 100 miles thick. It keeps the surface warm and protects it from radiation and small- to medium- sized meteorites.  EARTH’S ENERGY With a steady input of either light or chemical energy, cells can run the chemical reactions necessary for life. Important FEATURES OF EARTH Everything in Earth’s system “The most impressive attribute of the can be placed into one of Earth is the existence and amount of four major subsystems: land, liquid water on its surface,” said by water, living things, or air. Geoffrey Marcy, an astronomer at These four subsystems are the University of California. He also called “spheres”. said that no one knows why Earth Specifically, they are the has the exact amount of water it does, which relatively small “lithosphere” (land), considering that water molecules “hydrosphere” (water), outnumber silicate molecules in the biosphere (living things), and galaxy. “atmosphere” (air).  SLOGAN-MAKING 1.Start with your logo.
