Which of the following scenarios illustrates the proper use of a science tool?

Using a spring scale to test the amount of force used to move an object accurately showcases the proper use of a science tool. A spring scale is specifically designed to measure force, typically in units like newtons or pounds, which makes it ideal for determining how much force is required to move an object. This aligns directly with the fundamental purpose of the spring scale, allowing for precise measurement of force in physical science experiments. Utilizing tools in their designated roles maximizes the accuracy and reliability of the data collected during scientific investigations, which is essential for drawing valid conclusions.

The other scenarios illustrate misconceptions about the application of specific tools. For example, a thermometer is meant to measure temperature, not height, making its use in measuring plant height inappropriate. Similarly, a ruler is designed for measuring lengths or distances, not temperature, thereby demonstrating a misuse when attempting to gauge the temperature of a liquid. Lastly, a microscope serves to magnify small objects for detailed observation rather than measure pH, which is typically assessed using pH indicators or meters. Understanding the appropriate use of scientific tools is crucial for effective experimentation and accurate data interpretation.
