Lab techniques are the processes and practices that are recommended for using the various equipment in the laboratory. In this lesson, we will go over some of the most basic lab techniques you will need to know. Are you a student or a teacher?
It's important to learn proper lab techniques, or the processes and practices that are recommended for using the various equipment in the laboratory, for pouring, measuring, filtering, using gas burners and glassware. Pouring is done using a stirring rod, allowing liquids to flow down the rod.
When it comes to pouring substances in a laboratory, the technique has to be much more precise. So, what's the solution? The basic technique to pour liquid in a lab is to use a stirring rod, or another similar instrument. You use the stirring rod to connect the pouring spout from the source container to where you want the liquid to go.
Unwanted microorganisms can be introduced into samples by direct contact with contaminated surfaces or hands by touching either the growth media or the inner surfaces of the culture tube with objects that have not been sterilized. In addition, microbes in the air can enter tubes and plates of growth media by way of air currents.

Through a review of the literature, this paper asserts that four distinct styles of laboratory instruction have been utilized throughout the history of chemistry education: expository (traditional), inquiry, discovery, and problem-based.
Ensuring everyone is set up for mandatory safety training is necessary, as is making sure you outfit your lab with the basics, like a fire extinguisher, fire blankets, a first-aid kit, and emergency showers.
The laboratory techniques are very important in a researcher's life. These skills play a significant role in order to perform various experiments and to run various tests. Without proper knowledge, one can not apply these techniques in projects and researches. These techniques are vital for most of the experiments.
Introduction. Laboratory classes provide students with first-hand experience with course concepts and with the opportunity to explore methods used by scientists in their discipline. Leading a laboratory session has particular challenges and opportunities that differ from those in a standard classroom environment.
A lab course is a smaller, individual course component that supplements larger lectures. Labs allow for hands-on, practical exposure to subject matter. For instance, a biology lab may require students to dissect a frog and record the results in a journal.
List four things students should be before beginning any lab. Read instructions, Tie back long hair, Roll back loose sleeves, Put on safety goggles. List two things students should do after a lab. Wash hands with soap and water, Clean up your work area.
1. Dress appropriatelyBefore entering the lab, make sure to put on a lab coat. ... Wear closed shoes. ... Long pants are a must, as skirts and shorts expose the skin to dangerous chemicals.Avoid loose sleeves, as they are impractical when working.Tie back long hair. ... Only bring the things you need into the lab.More items...•

Laboratory experiences may enhance student understanding of specific scientific facts and concepts and of the way in which these facts and concepts are organized in the scientific disciplines. Developing scientific reasoning.
A 'wet-lab' is a traditional experimental laboratory in which scientific research is carried out using chemicals and biological samples (including patient material). These substances or materials require special handling by trained professionals, using sensitive equipment.
Flame Tests detect the presence of elements by dipping a wooden splint or nichrome wire in a sample of the element or its salt, then placing the sample over a Bunsen burner. The unique emission spectrum of the element present then causes the flame to briefly change color.
