A paper snake cut into a spiral shape spins when held over a heat source, demonstrating how convection currents move air and transfer heat.

1. Draw a snake in a spiral shape on a sheet of paper, or print a convection snake template.
2. Color and decorate the snake as desired.
3. Carefully cut out the spiral along the lines.
4. Tape a piece of cotton thread to the center end of the spiral so the snake can hang freely.
5. Hold the hanging snake above a gentle heat source, such as a candle, lamp, or radiator.
6. Observe as the snake begins to spin due to the movement of warm air rising.

• Try using different paper thicknesses to see how they affect the spinning speed.
• Test different heat sources such as a hair dryer on a low setting or a sunny windowsill.
• Make multiple snakes of different sizes and compare how quickly they spin.

• Adult supervision is essential when using a candle or any heat source.
• Keep the paper snake a safe distance from the flame to avoid fire hazards.
• Ensure the area around the heat source is clear of flammable materials.
• Do not leave the experiment unattended while heat is applied.

• Why does the snake spin when held over heat? (Because warm air rises, creating convection currents that move the snake.)
• What happens to the air particles near the heat source? (They move faster, spread out, and become less dense.)
• How does this demonstrate convection? (It shows how heat transfer through moving air causes circular motion.)
• Can you think of other real-life examples of convection? (Examples include radiators heating rooms and air rising over warm ground to form wind.)
