The scientist can use litmus paper or pH test strips to measure the approximate pH of swamp water. These tools are simple, inexpensive, and easy to use for a quick estimation of the water's acidity or alkalinity.
A pH indicator
The scientist should use a pH meter to measure the precise pH of the solution. This device provides an accurate numerical value for the acidity or alkalinity of the solution.
French scientist and statesman, Berthelot (1827-1907) in 1881
Mrs.Tuft used a hydrometer to determine the specific gravity of a liquid
Scientists use tools like graduated cylinders, beakers, and volumetric flasks to measure the volume of a substance. They then use scales to measure the mass of the substance. By dividing the mass by the volume, scientists can calculate the density of the material.

True. A scientist can observe and measure the color of matter to gather information about its properties or composition. This is a common technique used in various scientific disciplines such as chemistry, physics, and biology.
Most people just measure the circumference and divide by 3.14 (approximate pi) to find the (approximate) diameter.
