Matter Vocabulary
Anything that has mass and takes up space is called this
What is matter?
A balance is commonly used to measure this property of matter
What is mass?
If a material is attracted to a magnet, it has this property
What is magnetism?
You have an unknown material that is attracted to a magnet. Which test helped you identify this property?
What is a magnet test?
A raincoat is made from a material that does not easily allow water through. Which property is important?
What is low absorbency/water resistance?
The amount of matter in an object is called this
What is mass?
Mass is commonly measured in these units
What are grams?
A material that can soak up water, like a paper towel, has this property.
What is absorbency?
A mystery material has a mass of 50 g and a volume of 10 mL. What is its density?
What is 5 g/mL?
A refrigerator magnet sticks to the metal door. Which property allows this to happen?
What is magnetism?
The amount of space an object takes up is called this
What is volume?
A graduated cylinder can be used to measure this
What is volume?
The ability of a substance to dissolve in a liquid is called this
What is solubility?
A student puts an unknown powder into water. The powder disappears and mixes evenly into the water. What property does this demonstrate?
What is solubility?
Paper towels are designed to soak up spills. Which property makes them useful for this job?
What is absorbency?
A characteristic of a material that can be observed or measured is called this
What is a property?
A rock is placed in a graduated cylinder. The water level rises from 50 mL to 75 mL. What is the volume of the rock?
What is 25 mL?
A student scratches two materials. Material A scratches Material B. Which material is harder?
What is Material A?
A mystery material does not absorb water, is shiny, and is attracted to a magnet. Give two properties that could help identify the material.
Any two: magnetism, low absorbency, or reflectivity.
A jeweler wants to choose a material that is shiny and reflects light. Which property would they look for?
What is reflectivity?
This property describes how much mass is packed into a certain amount of space
What is density?
Two objects have the same volume. Object A has a mass of 20 g, and Object B has a mass of 40 g. Which object has the greater density?
What is Object B?
A shiny metal spoon reflects light. Which property is the student observing?
What is reflectivity?
You are given three unknown materials. Explain why scientists should use more than one property when trying to identify an unknown material.
Because using multiple properties provides more evidence and makes it easier to correctly identify the material.
A scientist needs to identify an unknown solid. She measures its mass and volume and also tests its magnetism, hardness, and solubility. Why is collecting all of this evidence useful?
Different materials can have similar individual properties, so using several properties provides stronger evidence for identifying the material.
