The 3 ways of heat transfer are : 2. Transfer of heat by touching is called ________. 3. Boiling water is an example of _________. 4. The element inside the oven which emits heat is an example of ___________ heat transfer. 5. All waves emit _______________. QUICK QUESTIONS : TUESDAY 1. Sound is a ________ type of wave. (transverse/longitudinal) 2. Light is a (taansverse/longitudinal) type of wave. 3. Mechanical waves, like sound needed a ___________ to travel. 4. Electromagnetic waves can travel in space. (T/F) 5. The higher the pitch, the higher the ____________. HOMEWORK : WEEK OF JAN. 59,2015 Review for the upcoming benchmark test in Science scheduled on January 13, 2015 Coverage will be : Waves, Sound, EM Spectrum and Heat Transfer ICE CREAM LAB : JANUARY 14 : WEDNESDAY / WHOLE CLASS! Items needed : 2 coolers of ice 3 gallons of whole milk 3 containers of half and half creamer (coffee creamer) 3 packs of rock salt 3 bags of sugar 3 vanilla flavor 5 big ziplock bags 5 small ziplock bags 2 boxes of spoons 2 big bowls 1 pack of napkins toppings LEARNING CENTERS FOR THE WEEK 1. Review Centers 2. Wave Lab 3. Literacy Station 4. NCFE station 5. discovery ed station ESSENTIAL STANDARDS : 6.E.2.1 By the end of the week I can : compare and contrast the crust, mantle and core of the Earth. describe the crust, mantle and core based on their relative position, composition and density. work in learning centers dealing with the Waves, sound, light and heat transfer increase Science literacy through reading, writing, speaking and listening Review for the benchmark test scheduled on Tuesday, January 13, 2015 Crust – the top layer of earth made of a thin layer of cool rock Lithosphere – the layer of earth made of the crust and the rigid rock of the upper mantle which is broken into tectonic plates Asthenosphere – the layer in earth’s upper mantle directly under the lithosphere in which rock is soft and weak because it is close to melting BENCHMARK REVIEW QUESTIONS 1. Which is one way sound waves are different from light waves? a. Sound waves travel through space but light waves cannot. b. Sound waves travel at a slower speed than light waves. c. Sound waves have shorter wavelengths than light waves. d. Sound waves are a source of energy but light waves are not. EARTH’S LAYERS VOCABULARY Inner core – a ball of hot solid metal at the center of the earth Outer core – liquid layer of metal that surrounds the inner core Mantle – earth’s thickest layer between the outer core and crust made of magma TUESDAY ACTIVITY : BENCHMARK REVIEW Matching type! Each group is given a puzzle packet containing questions and answers. Match the question with the answers, based on what we have learned from our previous review sessions. You will be given 15 minutes to complete the match, work with your group collaboratively! Answers will be shown after the 15 minute time frame! BENCHMARK QUESTION REVIEW Refer to common exam questions / eog questions NEW CONCEPT : TUESDAY The earth is composed - primarilyof rock. Three-fourths of the earth's surface is covered by a relatively thin layer of water (some of it frozen), and the entire planet is surrounded by a relatively thin layer of gas we call the atmosphere. The Earth has a solid inner core that is surrounded by a liquid outer core. NEW CONCEPT : TUESDAY The inner core is a solid section of the Earth and is unattached to the mantle, being suspended by the molten outer core. The inner core is predominantly iron metal with significant amounts of the element nickel. This inner layer in mutual combination with the rotational motion of the Earth creates a dynamo effect where a force field is generated. This field is also known as Earth's magnetic field. Cross-Section of the Layers of the Earth Tectonic plates – the process in which the motion of a hot material under the crust changes the crust of the Earth. These are called plate tectonics Continental drift – a hypothesis that Earth’s continents move on the surface Fault lines – a crack in Earth’s surface NEW CONCEPT : WEDNESDAY In terms of the physical aspects of the outer core, the layer is dense but not as dense as pure molten iron. Surrounding the entire dense, metallic core is a thick, hot, convective layer called the mantle. The crust consists of many continental and oceanic plates that have slowly moved and changed positions on the globe throughout geologic time. Pangaea – a hypothetical supercontinent in which all continents were once attached. It began breaking apart about 200 million years ago Convection – a process by which energy is transferred to cause warmer less dense air or liquid to rise while the dense cooler liquid or air is pushed down.
