Flashcard 1: Which property describes whether a material allows water to pass through it?
Answer: Permeability. Water flows through cloth but not through plastic sheets.
Flashcard 2: Identify the property tested when you compare how rough or smooth two materials feel.
Answer: Texture. Sandpaper feels rough while glass feels smooth to touch.
Flashcard 3: Which property describes a material’s ability to soak up water into its surface or spaces?
Answer: Absorbency. Paper towels absorb water while plastic repels it.
Flashcard 4: Which term means a characteristic you can observe or measure to identify a material?
Answer: A physical property. Observable or measurable characteristics help identify materials.
Flashcard 5: Which property describes the ability of a material to bend without breaking?
Answer: Flexibility. Rubber bands bend easily while glass rods break when bent.
Flashcard 6: Which property describes how easily a material breaks or shatters when force is applied?
Answer: Brittleness. Glass and ceramics shatter easily while metals bend first.
Flashcard 7: Which property describes whether a material dissolves in water?
Answer: Solubility. Sugar dissolves in water while sand does not.
Flashcard 8: Which property best distinguishes wax from metal if both are solid: melting point or color?
Answer: Melting point. Wax melts at low temperature while metal needs high heat.
Flashcard 9: Which property best distinguishes a sponge from a plastic block when both are the same size: absorbency or hardness?
Answer: Absorbency. Sponges soak up water while plastic blocks repel it.
Flashcard 10: Which property describes whether a material can be pulled into a wire?
Answer: Ductility. Most metals can be stretched into wires.
Flashcard 11: Which property describes the temperature at which a solid becomes a liquid?
Answer: Melting point. Each material has a specific melting temperature.
Flashcard 12: Identify the property being tested when a solid is placed in water to see if it dissolves.
Answer: Solubility. Testing if the solid dissolves in water.
Flashcard 13: Identify the property being tested when a nail is brought near a magnet to see if it is attracted.
Answer: Magnetism. Testing if the nail is attracted to the magnet.
Flashcard 14: Identify the property being tested when two objects are compared to see which scratches the other.
Answer: Hardness. The harder object scratches the softer one.
Flashcard 15: Which material property best distinguishes copper wire from a rubber band in a circuit?
Answer: Electrical conductivity. Copper conducts electricity; rubber doesn't.
Flashcard 16: Which property best distinguishes a glass window from a wooden board when light shines through?
Answer: Transparency. Glass is transparent; wood is opaque.
Flashcard 17: Which property describes whether light can pass through a material clearly, partly, or not at all?
Answer: Transparency (transparent, translucent, or opaque). Light passes through, partially, or not at all.
Flashcard 18: Which property describes a material’s resistance to being scratched?
Answer: Hardness. Harder materials scratch softer ones.
Flashcard 19: Which property describes whether a material can be bent without breaking?
Answer: Flexibility. Flexible materials bend; brittle ones break.
Flashcard 20: Which property describes how a material reflects light (for example, shiny or dull)?
Answer: Luster. Metals are shiny; non-metals are usually dull.
Flashcard 21: Which property tells whether a material dissolves in water?
Answer: Solubility. Soluble materials dissolve; insoluble don't.
Flashcard 22: Which property describes a material’s ability to transfer heat?
Answer: Thermal conductivity. Metals transfer heat well; insulators don't.
Flashcard 23: Which property describes a material’s ability to let electric current pass through it?
Answer: Electrical conductivity. Metals conduct electricity; insulators don't.
Flashcard 24: What is the formula for density using mass and volume?
Answer: D=Vm. Density equals mass divided by volume.
Flashcard 25: Which property describes how much mass is in a given volume of a material?
Answer: Density. Calculated as mass divided by volume.
Flashcard 26: Which property describes whether a material is attracted to a magnet?
Answer: Magnetism. Materials are either magnetic or non-magnetic.
Flashcard 27: What is a chemical property of a material?
Answer: A characteristic describing how a material can change into new substances. Involves reactions that create new substances.
Flashcard 28: Which property best distinguishes glass from wax paper when light shines through it?
Answer: Transparency. Glass is transparent; wax paper is translucent.
Flashcard 29: What property describes whether a material can be bent without breaking?
Answer: Flexibility. Rubber bands bend; glass shatters when bent.
Flashcard 30: Which property best distinguishes aluminum foil from plastic wrap when stretched?
Answer: Malleability. Aluminum can be hammered flat; plastic tears.
