Using Lab Apparatus_P01_lower_review

Introduction

Scientists use many tools with their investigations. Astronomers use telescopes. Telescopes help us look at far away objects. Other scientists use microscopes. Microscopes help us look at very small objects. Chemists use lots of tools when mixing, heating, or even applying pressure to chemicals. When a piece of equipment is made 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 things to consider when learning about these tools of science. First, it is important to learn the names of the tools you will be using. Next, it is just as important to know what tools to use when doing an investigation. Last, you will need to learn how to use these tools correctly.

Tools can be similar. But they may have different purposes. Improper use of tools can result in imprecise data. Imprecise data may keep a scientist from forming a good conclusion. You should become familiar with the lab apparatus you will use. Then, you will be able to choose the best tool for the job.

For example, both a beaker and graduated cylinder can 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 an exact amount, it would be best 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 is also for staying safe.  Some of the tools in science can be dangerous if not used correctly. Knowing the tools and how to use them will help everyone stay safe.
