Density
10/1/13
Cubs
Density The purpose of this experiment is to find out the density of the unknown solid object by determining the mass and the volume through the experiment. To do this we will be get the mass of the object and determine the volume of the object by placing it into a liquid. Then we will divide mass by volume and get its density.
Materials
3 buckets filled with water
Water
A bucket to measure volume
A stool
Measuring scale to measure weight
Notebook
Procedure
1. Find the weight of the student and then convert to mass in grams.
2. Next, the student will get into the bucket of water.
3. Slowly the student will dunk their entire body below the surface of the water.
4. Then the student will get out of the bucket.
5. Another student will scoop some water from the other bucket filled with water and pour it into the bucket the student went in.
6. As the water is being poured into the bucket all the way to the top, it is being measured as volume

Results
Conclusion This lad explained the facts and density and how to find density. Density is a physical property of matter, as each element and compound has a unique density associated with it. Density defined in a qualitative manner as the measure of the relative heaviness of objects with a constant volume. The formal definition of density is mass per unit volume. Usually the density is expressed in grams per mL. Density = mass volume = g/mL
