Alternative titles: Ice Melt Race: Wood vs Metal
Summary
Ever wondered why some surfaces feel colder than others, even when they’re the same temperature? Try this quick experiment by melting ice cubes on wood and metal to explore how heat moves differently through materials.
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?
