Real-Life Examples of Separation Techniques for Kids

📚 Quick Study Guide

• 💧 Filtration: Separating solids from liquids using a filter (like straining pasta).
• 🧲 Magnetic Separation: Using a magnet to separate magnetic materials from non-magnetic ones (like separating iron filings from sand).
• 蒸 Evaporation: Separating a soluble solid from a liquid by heating the solution until the liquid evaporates (like getting salt from saltwater).
• 🧺 Sieving: Separating different sized particles using a sieve (like separating sand from pebbles).
• ⚗️ Decantation: Separating liquids with different densities by carefully pouring the top layer into another container (like separating oil and water).
