Grade 1 science quiz on material properties and uses

📚 Quick Study Guide

• 🔍 Material Properties: Materials have different properties like hardness, flexibility, transparency, and absorbency.
• 🪵 Hardness: How easily a material can be scratched. Diamond is very hard!
• 🌱 Flexibility: How easily a material can bend without breaking. Rubber is flexible.
• 👓 Transparency: How much light can pass through a material. Glass is transparent.
• 💧 Absorbency: How much liquid a material can soak up. Paper towels are absorbent.
• 🔨 Uses of Materials: We use materials based on their properties. For example, we use glass for windows because it's transparent, and metal for pots because it can withstand heat.
• 🔥 Conductors: Some materials allow heat or electricity to pass through them easily. Metals are good conductors.
• 🧱 Insulators: Some materials do not allow heat or electricity to pass through them easily. Wood and plastic are good insulators.
