The Action |
Heat rising from a candle causes an aluminum coil to turn. | ||
Grade Level |
Grade 1 - Motion | ||
Materials |
Small candles (possibly birthday candles) Candle holders Needle and thread Aluminum foil Matches |
||
Instructions |
Make a "wind snake" by cutting the aluminum foil in a circular pattern (see picture). Suspend the snakes from the ceiling on a thread so they are approximately 25 cm from the tabletop. Light the candle and place it on the table directly below the wind snake. |
||
Safety |
Students must be made aware of the danger involved when using candles. | ||
Science Principle |
Hot air rises and as a result, the candle heats the air under the snake. The snake begins to turn as a result of the warm air rising and following the pattern of the coil. | ||
