Using Lab Apparatus_P01_review
Introduction
Scientists use many tools with their investigations. Telescopes are used by astronomers to look at far away objects. Other scientists use microscopes to look at very small objects. Chemists use a variety of equipment when mixing, heating, or even applying pressure to chemicals. When a piece of equipment is designed for a specific purpose it is called apparatus. Some of these tools may be familiar, while others will be new to you.
The Tools of Science
There are three important considerations when learning about these tools of science. First, it is important to learn the names of lab apparatus you will be using. Being able to explain to a colleague what tools were used to obtain your data is very important. Second, it is just as important to know what equipment to use when doing an investigation. Last, but certainly not least, you will need to learn how to use these tools correctly.
While tools may sometimes be similar, they may be used for different purposes. Improper use of tools can result in imprecise data. Imprecise data may keep a scientist from forming a good conclusion. By becoming familiar with the laboratory apparatus, you will be in a better position to choose the correct apparatus for the job.
For example, a beaker and a graduated cylinder could both be used to measure the volume of a liquid. If you were looking for an approximate amount, a beaker may be appropriate to use. If you needed to be very accurate, you would choose to use the graduated cylinder.
A hand lens and a microscope can both be used to take a closer look when making observations. A microscope uses light to look through objects. Materials you cannot see through, like a seashell, are better observed with a hand lens. Learning about lab equipment also relates to the importance of staying safe. Some of the tools in science can be dangerous if not used correctly. Knowing the science tools and how to use each tool will help everyone stay safe.
