How heavy is something? How much space does it take up? These questions lead us to two essential measurements—mass and volume. Mass tells us how much matter an object contains, while volume tells us how much space it occupies. We can measure mass using a scale and volume using graduated containers like beakers.
To measure mass, we use a scale or balance. First, place the object you want to measure onto the scale platform. The scale will display the mass of the object, usually in units like grams or kilograms. Digital scales are very accurate and easy to read. Let's see how this works with an apple.
To measure the volume of liquids, we use graduated containers like beakers or measuring cups. Pour the liquid into the beaker and read the level at eye level for accuracy. The markings on the side show the volume in milliliters or liters. Let's see how we measure 300 milliliters of water.
For irregular solid objects, we use water displacement to find volume. First, add a known amount of water to the beaker and note the initial level. Then carefully place the object into the water. The water level will rise. Subtract the initial volume from the final volume to find the object's volume.
In summary, mass and volume are fundamental measurements in science. Mass tells us how much matter an object contains and is measured using scales in grams or kilograms. Volume tells us how much space an object occupies and is measured using graduated containers in milliliters or liters. For irregular solids, we use water displacement. These measurements are essential in cooking, chemistry, physics, and many other fields.
