Hedef

Farklı yoğunluklardaki birbiriyle karışmayan sıvıları yüksek bir silindir içinde katman katman yerleştirerek sıvı yoğunluğu kavramını göstermek.

Arka Plan

Different liquids have different densities, and immiscible liquids will arrange themselves with the densest at the bottom and the least dense at the top. By carefully layering liquids such as honey, corn syrup, dish soap, water, vegetable oil, and rubbing alcohol, a dramatic rainbow column can be created. Small solid objects placed in the column float at the interface matching their density, further illustrating the concept.

Güvenlik Uyarıları

  • Rubbing alcohol is flammable — no open flames
  • Some liquids are sticky — clean spills immediately
  • Do not drink any of the layered liquids

Malzemeler

  • Honey (50 mL)
    Density ≈ 1.42 g/mL
  • Corn syrup (50 mL)
    Density ≈ 1.38 g/mL
  • Maple syrup (50 mL)
    Density ≈ 1.32 g/mL
  • Dish soap (50 mL)
    Density ≈ 1.06 g/mL
  • Water (dyed blue) (50 mL)
    Density = 1.00 g/mL
  • Vegetable oil (50 mL)
    Density ≈ 0.92 g/mL
  • Rubbing alcohol (dyed red) (50 mL)
    Density ≈ 0.79 g/mL
  • Food coloring (Various)
    To distinguish water and alcohol layers

Ekipman

Tall clear glass or graduated cylinder (500 mL) Funnel or turkey baster Small objects: grape, cherry tomato, ping pong ball, bolt, cork

Prosedür

1

Start with the densest liquid: pour honey slowly into the bottom of the tall glass.

2

Tilt the glass slightly and pour corn syrup slowly down the side. It should form a distinct layer on top of the honey.

3

Continue adding layers in order of decreasing density: maple syrup, dish soap, blue-dyed water, vegetable oil, and red-dyed rubbing alcohol.

15 dak Pour very slowly for clean layers
4

Observe the distinct layers. Gently drop small objects (grape, bolt, cork, ping pong ball) into the column and note where they settle.

5

Discuss why the layers form (density differences), why some are miscible and some immiscible, and why objects float at specific levels.

Beklenen Sonuçlar

Seven distinct layers should be visible, creating a colorful rainbow column. A metal bolt sinks to the bottom, a grape rests on the corn syrup, a cherry tomato on the dish soap, and a ping pong ball floats on top. Cork floats on the water layer.

Temizlik

Pour the column into a waste container (do not pour down the drain due to oil and syrup). Wash the glass with hot soapy water.
