Standard
PS.6.2.1: Use models to compare directional heat transfer (Conduction, Convection, Radiation).
Duration
60 Minutes (Single Period)
Subject
Physical Science / Physics
Learning Objectives
Identify and define the three primary methods of heat transfer: conduction, convection, and radiation.
Analyze visual models to determine the direction of heat flow (from hotter to cooler matter).
Compare the physical mechanisms (particle contact vs. fluid movement vs. electromagnetic waves) of each transfer type.
Core Vocabulary
Conduction
Heat transfer through direct contact between particles.
Convection
Heat transfer through the movement of fluids (liquids or gases).
Radiation
Heat transfer through electromagnetic waves across space/air.
Thermal Equilibrium
When two objects reach the same temperature and heat flow stops.

Instructional Sequence
01
Engage: The Campfire Mystery (10 mins)
Open the lesson by presenting the Campfire Slide . Ask students to identify three different ways they would feel heat if they were sitting by a fire:
"Why does the metal roasting stick get hot in your hand?"
"Why does the smoke and hot air rise above the flames?"
"Why can you feel heat on your face even if you aren't touching the fire?"
02
Explain: Direct Instruction (20 mins)
Distribute the Heat Hunt Doodle Notes . Guide students through the presentation.
Teacher Tip:
Encourage students to use specific colors: Red for heat source, Blue for cooler areas, and Yellow/Orange for the "transfer" energy. This helps them visualize the standard's focus on direction .
Focus on the Particle Models . Discuss how conduction requires touching, convection requires movement of mass, and radiation can move through empty space.
03
Explore: Model Matching (20 mins)
Students work in pairs to identify "Heat Hunt" scenarios on the slides. For each image shown, they must:
Identify the heat source.
Identify the cooler object.
Draw an arrow showing the direction of transfer.
Label the method (Conduction, Convection, or Radiation).
04
Evaluate: Exit Ticket (10 mins)
Wrap up by having students complete the "Heat Direction Challenge" on the back of their doodle notes. They must explain why heat always flows from warmer to cooler matter until equilibrium is reached.
Scaffolding & Extension
Support
Provide word banks and pre-drawn arrows for direction of heat flow. Use real-world physical examples (ice cube in hand).
Extension
Have students research "Thermal Insulators" vs "Conductors" and how they affect the rate of transfer in these models.

The Big Question
How does heat energy move between objects?
Heat energy ALWAYS moves from:
HOT
Source
COLD
Target
Thermal Equilibrium
This transfer continues until both objects reach the same temperature.
Method 1: Conduction
"The Hand-Off"
1
Requires DIRECT CONTACT between objects.
2
Heat is transferred through particle vibrations.
3
Works best in solids (dense particles).
Contact Model
Method 2: Convection
"The Loop"
1
Transfer through the movement of fluids.
2
Hot fluids rise and Cold fluids sink.
3
Creates a Convection Current.
Fluid Loop Model
Method 3: Radiation
"The Signal"
1
Transfer through Electromagnetic Waves.
2
Does NOT require matter.
3
Can move through the vacuum of space.

Teacher Reference Sheet - Doodle Notes Vocabulary & Lab Challenge
Conduction
Definition: Heat transfer through direct contact between particles. Heat energy "bumps" from one particle to the next.
Example: Metal spoon in hot coffee; touching a warm car seat.
Convection
Definition: Heat transfer through the movement of fluids (liquids and gases). Warmer, less dense matter rises; cooler, denser matter sinks.
Example: Boiling water; hot air balloons; ocean currents.
Radiation
Definition: Heat transfer through electromagnetic waves across space. Does not require matter to travel.
Example: Sunlight hitting Earth; heat from a toaster or heat lamp.

Reflection Answer Guide
1. Why does heat move towards the colder object?
Heat is energy; nature naturally flows from high energy (hot/fast particles) to low energy (cold/slow particles) to reach equilibrium.
2. Which method is "fastest"?
Radiation is the fastest (speed of light). Conduction speed depends on the material; convection takes time for fluid to physically move.
3. Is the metal desk colder than the wood table?
No, they are usually the same temperature if in the same room. Metal feels colder because it is a better conductor and pulls heat away from your hand faster.
