Triple Beam Balance (TBB)

Metric Ruler

Spring Scale

Meters

### What is the unit for volume(soild)

Cubic Centimeters

Liters

g/cm3

g/mL

Newtons

### How to find the volume of an regular object

First, you would find the width, height and the length of the object. Then you would multiply those numbers together. That's the volume of the object

### How to find the volume of an irregular object

You would find the volume of an irregular object by first filling up an graduated cylinder with water up to a certain level(like 50 mL). Then put the object inside the graduated cylinder. The water level now says 67 mL so you subtract 67 from 50 to get 17 so the object has a volume of 17cc (1 cc is equal to 1mL)

### How to find the volume of liquids

You would first pour the liquid into the graduated cylinder. Then you would read the level that the water is on and you would get the volume of the liquid.

### How to find the mass of a soild

You find the mass of a soild by putting the object on a triple beam balance. Then you would used the 3 beams and move the 100-500 beam first. Once the scale drops down, stop and move back one. Do this to the 10-100 beam too. Then for the last beam (the 1-10), move the beam until it goes down. Then you would want to move the scale back until the arrow on the top of the balance is lined up with the 0 line mark.

### How to find the mass of liquids

First you would find the mass of the container that you are putting the water in, then you would put the water in the container and measure the mass of that, Lastly you would subtract the water with the container with just the container to get the mass of the water.

### Determinded the appropriate unit for meausring depending on the size of the object

Kilo,Hecto,Deka,Unit,Deci,Centi,Milli are the prefixs for the appropriate units

### Explain why the mass of an object is constant but its weight can change.

Mass can only be changed if you take something away or add something but weight can change because of gravity so if u went to another planet, your mass would be the same because you haven't added or taken away something but since their is a different gravity there your weight would change.

D=M/V

### Calculate density given mass and volume

You can calculate density by doing D=M/V

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

You can caculate density when you're given the mass and volume of the object. You do it by doing mass divided my weight

1 g/mL

### Why does an object sink/float Describe using the concept of density

An object sinks or floats when the object's density is greater that the liquid's density, it will sink but if the object's density is less that the liquid's density it will float on top of the liquid.
