- Slide 3
- What is temperature? Any ideas? Think, pair, share (1min)
- Slide 4
- 2 things you need to know: 1.All things are made of atoms or particles that are too small to see
- Slide 5
- 2. The particles are always moving in all directions.
- Slide 6
- Particle Movement in a Solid, Liquid, Gas Students as particles demo
- Slide 7
- Back to Temperature The measure of kinetic energy of the particles in an object Temperature = Kinetic energy of particles
- Slide 8
- Measuring Temperature 2 ways: 1.Fahrenheit Scale: At what temp does H 2 O freeze?________ At what temp does H 2 O boil?____
- Slide 9
- Measuring Temperature 2. Celcius Scale: At what temp does water freeze?_____ At what temp does water boil?_____
- Slide 10
- What is heat? Think about this : What happens to your hand when you grab a cold drink out of the fridge?
- Slide 11
- Heat The transfer of energy from one object to another Flows from warmer to cooler objects
- Slide 12
- Lets go back to this situation Knowing what you know about heatthink about this: What happens to your hand when you grab a cold drink out of the fridge?
- Slide 13
- Midpoint Review How are temperature and kinetic energy related? Heat is transferred how?
- Slide 14
- Heat Transfer There are 3 types: Conduction Convection Radiation
- Slide 15
- Conduction Transfer of energy by collisions of molecules in a material (2 things touching) Usually happens in solids
- Slide 16
- Conduction
- Slide 17
- Which spoon would you rather cook with? metal wooden Metal is a good conductor
- Slide 18
- Insulators Some things are bad conductors They can be used as insulators Sweaters Blankets Plastics Wood rubber
- Slide 19
- Convection Heat is transferred between objects of different temperatures Most common in gases and liquids
- Slide 20
- Examples of Convection Birds can float with out flapping wings Heating your home
- Slide 21
- Radiation Transfer of heat energy by waves
- Slide 22
- Examples of Radiation Heat from fire Microwave heating food
- Slide 23
- Heat BrainPop BrainPop
- Slide 24
- Quick Review Heat is transferred from ______ things to _______things. What are the 3 types of heat transfer? This is more common in solids____ This is more common in liquid/gas_
