Statement of the Problem:

We were trying to build a density jar with four visible liquid layers, with objects in three of those layers. At the beginning of the lab, I thought that it would be easy to find four stackable liquids, I was wrong. Before we started the lab we did a lot of other labs dealing with density, such as the "Liquid Rainbow", and the "Liquid Density" labs.

Objective:

I kept trying liquids and objects until I found four liquids, and three objects that I thought would work.

Materials:

1-250 ml beaker

1 electronic balance

Test tubes

Droppers

Liquids

Objects

1 jar

1 long ruler with no holes

Salt

Graduated cylinders

Procedure:

1. Get all of your materials

2. Place the beaker on the balance and press "on" or "reset"

3. Put 25ml of water in the beaker and put it back on the balance

4. Make a chart to record the data and then do so.

5. Find the density by ...
