Examples of materials that dissolve in water for kids

📚 Quick Study Guide

• 💧Solvent: Water is often called the 'universal solvent' because many substances dissolve in it.
• ➕ Solute: The substance that dissolves in a solvent.
• 💡Solution: The mixture formed when a solute dissolves in a solvent. For example, salt water is a solution of salt (solute) in water (solvent).
• 🌡️ Temperature: Usually, increasing the temperature of the water helps more of a solid solute to dissolve.
• 🍚 Examples of Soluble Materials: Salt, sugar, honey, powdered drink mixes (like Kool-Aid), and some types of soap.
• 🧱 Examples of Insoluble Materials: Sand, rocks, plastic, metal, and oil do not dissolve in water.
• 🧫 Dissolving at a Molecular Level: Dissolving happens when the molecules of the solute spread evenly among the molecules of the solvent.
