How Do We Measure and Observe Matter? CN

Name ______Room ______How do we measure and observe matter? CN Matter is anything that has mass and takes up space. Matter is made of tiny particles called molecules. Matter has properties. These are special things about matter that can be measured and observed. A property can be used to describe how an object looks, feels (hardness or texture), acts, or tastes. Some physical properties are mass, volume, size, shape, color, texture, state.

1. The measure of the amount of matter in an object is called mass. We measure mass with a scale balance. Mass is measured in grams (g). 2. The amount of space matter takes up is called volume. We measure volume with a graduated cylinder, meter stick or ruler. Volume is measured in milliliters (mL) with a graduated cylinder. 3. State of matter is a physical property. Matter can be a solid, liquid or gas. Air is an example of gas. 4. Length, width and height are physical properties related to size. We measure distance with a ruler, tape measure or meter stick. Scientists use meters, centimeters and millimeters to measure these properties. 5. You use your five senses to make qualitative observations. Shape, color and texture are physical properties we can observe using our 5 senses. Texture is how things feel when we touch it (rough, bumpy, smooth, sticky, or hard). Odor is a property identified using the sense of smell. The sense of sight can be used to determine an object’s luster or the ability of an object to reflect light.
