6th U 3.1 Science
6th U 3.1 Introduction to Matter
| Question | Answer |
|---|---|
| Anything that has mass and takes up space. | Matter |
| ___ and ___ are not matter. | Light and sound |
| ___ describes the amount of matter in an object. | Mass |
| A ___ is the unit of mass we use most often. | Gram |
| ___ is a measure of the gravitational force on an object. | Weight |
| Gravitational force keeps objects on Earth from floating into ___. | Space |
| The greater the mass of an object is the greater the ___ force on the object, and the greater the object's weight will be. | Gravitational |
| Mass is often measured by using a ___. | Triple-beam balance |
| Weight is measured with devices such as the ___. | Spring scale |
| Weight is a measure of gravitational force, it is given in units of force such as ___. | Pounds |
| The standard scientific unit for weight is the ___ | Newton (N) |
| One newton is about ____ of a pound. | One-fourth |
| All matter takes up space. The amount of space that an object takes up, or occupies, is known as the objects ___. | Volume. |
| To find the volume of objects with well-defined shapes, such as a rectangle, you use ___. | Formulas |
| The volume of a solid is measured in units of length ___ | Cubed (3) |
| ___ are used to measure liquid volume. | Graduated cylinder |
| The volume of liquids is often expressed in ___ or ___. | Liters (L) or milliliters (mL) |
| When an object is placed in water, the object pushes the water out of the way. This is called ___. | Displacement |
| Displacement can be used to measure the volume of an ___ shaped object. | Irregularly |
| When using water displacement remember that 1mL of water is equal to __. | 1 cm3 |
| __ and ___ are properties of all substances that are related to another property called density. | Mass and Volume |
| ___ is a measure of the amount of mass in a given volume. | Density |
| Which has the most density, a cup of water or a bucket of water? | Neither, density remains the same n a given substance. |
| The formula for density is ____. | mass divided by volume |
| ___ is the amount of space that matter in an object occupies. | Volume |
| ___ is anything that has mass and takes up space. | Matter |
| ___ is the amount of matter in an object. | Mass |
| ___ is the measure of the amount of matter in a given amount of space. | Density |
| ___ is the measure of the gravitational force on an object. | Weight |
| How do you know that air is matter? | Because it takes up space and has mass. |
| Is it possible for an object's weight to change while its mass remains constant? | Weight is the gravitational pull of an object. We would weigh less on the moon, less gravitational pull, than we do on Earth. Mass is the amount of matter in an object. We would have the same mass on the moon as we do on Earth. |
