  1. Objective 05/02/2013 Page SW be introduced to new forms of energy and connect them to energy terms learned in Earth science through notes and practice. Jumpstart All forms of matter, whether a solid, liquid, or gas, are composed of atoms or molecules in ____________ motion. Because of this, all atoms have ________________ energy. When a substance is heated, the atoms move _____________. When a substance is cooled, the atoms move _____________. The "average motion" of the atoms that we sense is what we call ________________ Word Bank: temperature, slower, constant, faster, thermal (heat)

  2. Introduction to Energy

  3. Packet 13- Page 1 What is Energy?? • Energy- the ability to do work • Energy can be transferred from one object to another by doing work • When work is done on an object, it results in a change in the object's motion (more specifically, a change in the object's kinetic energy)

  4. Temperature vs. Heat Page 1- Temperature and heat ARE NOT technically the same thing. • Temperature- a MEASURE of the average kinetic energy of the molecules of a substance • Heat – the TRANSFER of thermal energy from a warmer object to a cooler object • Note: This is a different definition than the “common” one people use daily

  5. Facts about Water. • Hydrology- study of water Facts: • Nearly 70% of the earth's surface is covered with water • Most of the earth's water is either salt water (97%) or in the form of ice and snow (2%) • Only 1% of the earth's water is available for us to drink What do you already know about the Water Cycle?

  6. Continuous process: same water used over and over again The water on the earth today has been there for millions of years Water moves: earth  air  earth Water changes: solid(snow and sleet)  liquid (rain, river water, groundwater)  gas (water vapor) Water Cycle

  7. 7.6- TSW DESCRIBE HOW SOLAR ENERGY DRIVES THE WATER CYCLE • How does solar energy drive the water cycle? • Solar energy heats water on the surface, causing it to evaporate • SOLAR ENERGY DRIVES THE WATER CYCLE

  8. Solar Energy and the Water Cycle • Evaporation- liquid absorbs enough energy to change into a gas • Transpiration- water evaporates through a plant's leaves • Condensation- gas (water vapor)  liquid • Precipitation- forms of water that fall back to the Earth's surface • Depends on temperature: rain, sleet, hail, or snow

  9. Packet 13, Page 1Heat Transfer~Transfer of thermal energy~ Heat is transferred through: 1. Conduction 2. Convection 3. Radiation

  10. Conduction- transfer of heat through a solid material; transfer of energy from one molecule to another; occurs when molecules hit against each other • similar to a game of pool where one moving ball strikes another, causing the second to move

  11. Conductor- a material which easily allows the flow of electricity or heat through it • Most metals are good conductors • Metallic bonds = hippie bonds = free flowing e’ • Ex. iron, copper • Insulator- a material which does not easily allow the flow of electricity or heat through it • Ex. glass, plastic, rubber, air, wood • used to protect us from the dangerous effects of electricity flowing through conductors

  12. Convection- transfer of heat by the movement of a fluid (liquid or gas); Convection current- circular motion caused by convection; hot rises, cold falls

  13. Radiation- transfer of energy by electromagnetic waves

  14. Radiation- transfer of energy by electromagnetic waves

  15. Objective 05/03/2013 Page 124 SW be introduced to new forms of energy and connect them to energy terms through book work. Jumpstart How does the hydrosphere drive all of our other Earth systems?

  16. Thermal Energy and Heat Page 439 in blue book Page 2 in Packet 13

  17. Understanding the states of matter is important to engineers and other builders. However, those who build out of ice must have a special knowledge of the solid state of water. • Building Igloos or Snow-and-Ice Houses- After the blocks are secured, a lamp is lit inside. Heat from the lamp __________ the snow on the inside walls. The water would then _________ when cold air was let in from the outside. melts freeze • The melted and rehardened snow functions as a cement. Gradually, the heat from people living and working inside changes the snow dome into a solid dome of ice!
