====Summary====                   
{{$demo.summary}}



====Procedure====  
- Freeze a tray of ice cubes.  
- Place one ice cube on a piece of wood and another on a piece of metal.  
- Watch closely to see which ice cube melts faster.  
- Touch the dry parts of both surfaces—do they feel the same? Which one feels cooler?

====Variations====
- Try using different metals (like aluminum vs. steel) to compare melting speeds.  
- Test insulators like plastic or fabric alongside wood and metal.  
- Place both surfaces in the sun and see if the results change.



====Safety Precautions====
- If testing with very hot metal (left in the sun or near heat), handle with care to avoid burns.  
- Melted water may make surfaces slippery—wipe up spills quickly.




====Questions to Consider====
- Which ice cube melted faster: the one on wood or the one on metal?  
- Why does metal feel colder to touch than wood, even though both are at room temperature?  
- How does this relate to the way oven mitts protect your hands from heat?
