1. TURBO TAKS Week 6 Lesson 1: Body Systems Lesson 2: Heat Transfer Lesson 3: Waves Lesson 4: Physics Equations

2. Lesson 2: Heat Transfer

3. Conduction Transfer from one substance to another by direct contact of molecules. THINK: Solids Example: When you touch a hot stove!

4. Convection Heat carried from one place to another in a liquid or a gas as molecules move in currents caused by density differences. THINK: Liquids and Gases Example: Heat leaves the coffee cup as the currents of steam and air rise.

5. Radiation Heat (thermal energy) in the form of electromagnetic radiation Examples: The sun warming your face. Warmth you feel sitting close to a campfire.

6. Lesson 3: Waves A wave is any disturbance that transmits energy through matter or space

7. Types of Waves Transverse Wave Produced by waving a rope or slinky spring up and down Can be made on the surface of water; ripple on a pond Example: Light wave

8. Parts of a Wave

11. Types of Waves Compression/ Longitudinal wave Produced by moving a slinky spring back and forth. Example: Sound

12. Characteristics of Waves Frequency- the measurement of the number of times that a repeated event occurs per unit of time High pitch noises = high frequency Wavelength- distance from a point in a wave to the next point on the next wave in the same phase Velocity = wavelength x frequency

13. Wave Properties Reflection When light rays bounce off the surface of an object Refraction The bending of light as it passes from one medium into another.

14. Wave Properties Diffraction Occurs when a wave passes through a gap between two barriers and spreads out into a circular pattern. Interference A wave interaction that occurs when two or more waves overlap.

15. Wave Properties Resonance What occurs when an object vibration at or near a resonant frequency of a second object causes the second object to vibrate. Common in tuning forks and other musical instruments Example: Ear  hearing
