Experiment 2
Density Ball: How to make a standard for measuring density

Purpose/Hypothesis

This experiment is designed to create a standardA base for comparison.. A standard is an object or instrument that has a fixed value. In this experiment, you will create a standard for measuring the density of a solution, called a density ballA ball with the fixed standard of 1.0 gram per milliliter, which is the exact density of pure water.. A density ball has the fixed standard of 1.0 gram/milliliter, which is the exact density of pure water. You will then determine if your standard can accurately indicate if a water sample's density is greater than or equal to pure water.

This experiment is similar to Experiment #1, except here you will determine...
