### Mass

The amount of matter in an object

### Volume

The amount of capacity or liquid occupied by an object

### Density

Mass/volumecand if something is more dense than water than it will sink

### Weight

A measure of the force of gravity on an object

### Grams

A unit used to measure mass

### Liters

A unit for volume

### Meters

Metric unit of length measurement

### Cubic Centimeters

A unit to measure volume

### Newtons

A unit to measure weight

### Triple Beam Balance

A tool used to measure mass

A tool used to measure liquid volume or for the Displacement method

### Displacement Method

An irregular shaped object will be placed in a graduated cylinder to measure the volume of that object

### Meniscus

The bottom of the disc in a graduated cylinder when water is inside

### What tool is used to measure mass

Triple Beam Balance

meter stick

Metric Ruler

Spring Scale

### Viscosity

A liquid's resistance to flow

Grams

### What unit is used to measure volume

Cubic Centimeters (cm3) or for liquid a Graduated Cylinder

### What unit is used to measure density

You can do Mass/Volume

Newtons

### How to find the volume of regular objects

Use a metric ruler and measure height, length, and width

### How to find the volume of irregular objects

Use the displacement method or if its bigger than a graduated cylinder put the object in a beaker and the water that comes out pour into a graduated cylinder

### How to find the volume of liquids

Use a graduated cylinder and pour inside

### How to find the mass of a solid

Use a triple beam balance ot electric scale

### How to find the mass of a liquid

Put liquid into a graduated cylinder and measure with an electronic scale than subtract the graduated cylinder's mass

### List the units for measuring from smallest to largest

millimeter, centimeter, decimeter, meter, dekameter, hectometer, and kilometer

### Compare mass and weight

Mass is the amount of matter you have or an object has and never changes unless you cut off or add. Weight depends on the gravitational pull of where you are.

### What is the formula for density

Mass divided by Weight M/V
Think if a heart

9/9=3 g/cm3

### Explain how to find the density of any object

Divide mass by weight

1 g/mL

### Why does an object float or sink. Relate to density.

If the object is denser than water it will than sink because it has more molecules packed into it. It will float if it is less dense than water because less molecules are packed into the object.
