Using Lab Apparatus 820L_Rev

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.

Types of Lab Apparatus

There are two basic types of lab apparatus: those that measure and those that aid in the process of collecting data. Think of a time you worked at home. Maybe your mother asked you to dig a hole to plant a new flower she bought at the garden center. You needed a shovel to dig a hole for the plant. You used a tape measure to make sure the hole was deep enough. One tool was for measuring, while the other aided you with a process.

You have probably heard of tools such as a thermometer, meter stick and a balance. These tools are used to measure temperature, length, and mass. In other words, they are data collection devices. What they collect is the evidence that scientists use that will later help them draw conclusions.

Other tools of science are used to help influence the science inquiry. For example, some tools like a Bunsen burner may be used to heat items. Tools can also be used for mixing, heating, cooling, and even applying forces. These examples are only a small set of the long list of science equipment. There are many different tools and new devices being developed daily.

Using equipment to gather data must be done with care. Tools are only as accurate as the person using them. Human error accounts for much of the measuring problems found in science. Many of the tools you will be using are capable of great precision in the hands of an expert. With practice, you will become an expert. 

 To be a scientist assumes you are curious. To find answers requires looking carefully. Measurements must be taken in a careful and precise manner. All the looking in the world may not reveal the answer. The point to be made is superior analysis starts with data collection. The quality of this data is dependent on the care and precision in which you use the tools of science.

Conclusions

For now, it is important to listen to your teacher. They will explain the instructions in the lab and the tools you will use. As you spend more time in the lab, you will better learn the names of some basic apparatus. You will learn how to properly use the equipment. By learning how to use the equipment you will be able to collect good data and be safe at the same time. You will become a great scientist and an expert in the use of scientific tools.
