WELCOME TO OUR SCIENCE CLASS MODULE 4 Prepared by: Sir Gelo Espino OPENING PRAYER CHECKING OF ATTENDANCE REVIEW QUESTIONS? WHEN YOU SAW THESE PICTURES, WHAT WORD COMES TO YOUR MIND? SOUND  MODULE 4 EFFECTS OF TEMPERATURE TO THE SPEED OF SOUND Prepared by: Sir Gelo Espino LEARNING OBJECTIVES THE STUDENTS SHOULD BE ABLE TO; 1. INVESTIGATE THE EFFECT OF TEMPERATURE ON THE SPEED OF SOUND 2. INFER HOW THE MOVEMENT OF PARTICLES OF AN OBJECT AFFECTS THE SPEED OF SOUND THROUGH IT GUIDE QUESTIONS: 1. WHAT IS THE SIMPLE DEFINITION OF SOUND? 2. WHERE DOES SOUND TRAVEL? 3. WHY IS THERE NO SOUND IN A VACUUM? 4. WHAT IS THE DIFFERENCE BETWEEN HIGH FREQUENCY AND LOW FREQUENCY? WHAT ARE THE OTHER EXAMPLE OF SOUNDS IN YOUR DAILY LIFE? SOUND IS CREATED BY VIBRATING OBJECT IF AN OBJECT VIBRATES, IT CREATES SOUND ENERGY HOW DOES A SOUND TRAVEL? SOUND TRAVELS IN THE FORM OF SOUND WAVES WHERE DOES THE SOUND TRAVELS? SOUND TRAVELS THROUGH THREE STATE OF MATTER SOLID LIQUID GAS HOW DOES A SOUND TRAVEL IN THE FORM OF SOUND WAVES? FACTORS AFFECTING THE SPEED OF SOUND 1. MOLECULES FACTORS AFFECTING THE SPEED OF SOUND 2. ELASTICITY OF AN OBJECT FACTORS AFFECTING THE SPEED OF SOUND 3. DENSITY OF AN OBJECT DENSER OBJECTS RESULTS TO SLOWER SPEED OF SOUND LESS DENSE OBJECTS RESULTS TO FASTER SPEED OF SOUND FACTORS AFFECTING THE SPEED OF SOUND 4. TEMPERATURE HOW DOES A TEMPERATURE AFFECT THE SPEED OF SOUND? GUIDE QUESTIONS: 1. WHERE DOES THE SOUND TRAVEL FASTER? HIGH TEMPERATURE OR LOW TEMPERATURE? 2. WHY DOES THE SPEED OF SOUND VARIES IN HIGH AND LOW TEMPERATURE? WHERE DOES THE SPEED OF SOUND TRAVEL FASTER? SUMMER? WINTER? GUIDE QUESTIONS: 1. WHERE DOES THE SOUND TRAVEL FASTER? HIGH TEMPERATURE OR LOW TEMPERATURE? 2. WHY DOES THE SPEED OF SOUND VARIES IN HIGH AND LOW TEMPERATURE? WHY DOES THE SPEED OF SOUND TRAVELS FASTER IN HIGHER TEMPERATURE? WHY DOES THE SPEED OF SOUND TRAVELS FASTER IN HIGHER TEMPERATURE? WHY DOES THE SPEED OF SOUND TRAVELS FASTER IN HIGHER TEMPERATURE? WHY DOES THE SPEED OF SOUND TRAVELS FASTER IN HIGHER TEMPERATURE? WHY DOES THE SPEED OF SOUND TRAVELS FASTER IN HIGHER TEMPERATURE? PROPERTIES OF SOUND PROPERTIES OF SOUND 1. REFLECTION THE TURNING BACK OF WAVE AS IT HITS A BARRIER PROPERTIES OF SOUND 1. B. REVERBERATION REFERS TO MULTIPLE REFLECTIONS OR ECHOES IN A CERTAIN PLACE PROPERTIES OF SOUND 2. REFRACTION INVOLVES A CHANGE IN DIRECTION OF WAVES FROM ONE MEDIUM TO ANOTHER PROPERTIES OF SOUND 2. REFRACTION THE SOUND WAVE TRAVELS FROM AIR OF HIGHER TEMPERATURE TO LOWER TEMPERAURE PROPERTIES OF SOUND 2. REFRACTION THE SOUND WAVE TRAVELS FROM AIR OF HIGHER TEMPERATURE TO LOWER TEMPERAURE WELCOME TO OUR SCIENCE CLASS MODULE 4 Prepared by: Sir Gelo Espino
