## 15 terms

### WEIGHT

a measure of the force of gravity on an object.

### MASS

a measure of how much matter is in an object.

### VOLUME

the amount of space that matter occupies

### DENSITY

the measurement of how much mass of a substance is contained in a given volume.

### INTERNATIONAL SYSTEM OF UNITS (SI)

the system of units used by scientists to measure the properties of matter.

### MATTER

the "stuff" that makes up everything in the universe.

1. length
2. mass
3. volume
4. density

### WHAT IS THE DIFFERENCE BETWEEN MASS and WEIGHT?

If you move an object away from Earth, its weight changes (because of gravity) but its mass stays the same.

### HOW DO WE MEASURE MASS? WHAT SCIENTIFIC TOOL DO WE USE?

We place an object on a triple beam balance and record the number in grams.

### WHAT ARE THE METRIC UNITS FOR MASS?

Grams and kilograms.

### HOW DO WE MEASURE THE VOLUME OF A REGULAR OBJECT?

We use a ruler to measure length, width and height. Then, we multiply length x width x height to calculate volume.

### WHAT IS THE FORMULA FOR CALCULATING VOLUME?

Length X Width X Height
LxWxH
