Vocabulary Dominoes: Thermal Energy and Energy Transfer NGSS MS-PS-3-3 and 3-4 - Free Printable

It looks like you've uploaded an image of a science activity titled "Conduction, Convection, and Radiation Dominoes" — a matching or sorting game designed to help students understand the three main methods of heat transfer: conduction, convection, and radiation.

The goal of this activity is to match each image with the correct method of heat transfer. Let's go through the images and determine which heat transfer method applies to each scenario.

---

🔹 Understanding the Three Methods:

1. Conduction: Heat transfer through direct contact between materials (e.g., a spoon in hot water).
2. Convection: Heat transfer through fluids (liquids or gases) via circulation (e.g., boiling water).
3. Radiation: Heat transfer through electromagnetic waves (e.g., sunlight).

🔍 Image-by-Image Analysis:

#### 1. Boiling Water
- Left side: Pot with bubbles → Boiling water.
- Right side: Same pot, but labeled "Boiling Water".
- ✔ Answer: Convection
> Because boiling involves heated water rising and cooler water sinking — convection currents.

#### 2. Iron
- An iron being used to press clothes.
- ✔ Answer: Conduction
> The iron heats up and transfers heat directly to fabric via contact.

#### 3. Thermal Insulator (Beaker with object hanging)
- A beaker with liquid and a thermometer; object suspended.
- Labeled “Thermal Insulator”.
- ✔ Answer: Thermal Insulator
> This shows something that *prevents* heat transfer — not a method, but a material property.

#### 4. Flip Flop (Plastic)
- Plastic flip flop.
- ✔ Answer: Conduction
> Plastic conducts heat slowly, but if it’s on a hot surface, heat transfers by conduction.

#### 5. Spoon heating up in hot water
- Spoon in a pot of hot water.
- ✔ Answer: Conduction
> Direct contact between hot water and spoon metal → conduction.

#### 6. Frying an egg
- Egg in a frying pan.
- ✔ Answer: Conduction
> The pan heats the egg via direct contact.

#### 7. Frying pan with egg (same as above?)
- But now labeled “Convection”?
- Wait — actually, this is likely a mistake unless air movement is involved.
- However, cooking in a pan is primarily conduction.
- But if it’s a pan with oil circulating? Then maybe convection.
- ✔ Answer: Conduction (unless specified otherwise).

> ⚠️ Note: Some versions may label this as convection if oil is bubbling and circulating.

#### 8. Oven or Air Fryer
- Oven with food inside.
- ✔ Answer: Convection
> Air circulates around food — convection.

#### 9. Oven Mitt
- Oven mitt protecting hand from hot oven.
- ✔ Answer: Thermal Insulator
> It prevents heat transfer via conduction.

#### 10. Sun (Light)
- Sun emitting rays.
- ✔ Answer: Radiation
> Sunlight travels through space as electromagnetic waves.

#### 11. Microwave
- Food in microwave.
- ✔ Answer: Radiation
> Microwaves use electromagnetic radiation to heat food.

#### 12. Lab Burner
- Bunsen burner flame.
- ✔ Answer: Conduction
> Flame heats container directly via contact.

> ⚠️ But wait — flames also involve radiation and convection. However, direct heating of a container is usually conduction.

#### 13. Wood
- Two logs of wood.
- ✔ Answer: Thermal Insulator
> Wood is a poor conductor — insulating.

#### 14. Metal Horseshoe
- Metal horseshoe, possibly heated.
- ✔ Answer: Conduction
> Metal conducts heat well.

#### 15. Ice melting in hand
- Ice in someone’s palm.
- ✔ Answer: Conduction
> Body heat transfers to ice through direct contact.

#### 16. Title card: Conduction, Convection and Radiation Dominoes
- Just the title — no answer needed.

✔ How to Play the Domino Game:

- Cut out each rectangle.
- Match the image on one end with the correct term on another.
- For example:
- "Boiling Water" connects to "Convection"
- "Sun (Light)" connects to "Radiation"
- "Spoon heating up" connects to "Conduction"

---

💡 Tips for Teaching:

- Emphasize that conduction = touch
- Convection = fluid motion (air/water)
- Radiation = no medium needed (sun, microwaves)
