TExES Life Science: Lab Equipment, Processes & Safety - Chapter Summary
If you need a little extra help getting ready for the TExES Life Science test, we've got you covered. You're likely to encounter test questions about laboratory safety and use, so let us help you prepare. These lessons guide you through laboratory fundamentals including:
- Types of laboratory equipment
- Safety processes and equipment for the lab
- Handling biologic and chemical hazards
- Common lab techniques like spectrophotometry, centrifugation, microscopy, dissection
- Ethics of studying living organisms in the lab
Our lessons are short but thorough and can easily be watched as many times as you'd like. They've been created by our instructors who are science experts. You can contact them if you have any questions. Take the practice quizzes that follow each lesson to gauge if you're ready to move on to the next topic.
TExES Life Science: Lab Equipment, Processes & Safety - Chapter Objectives
The TExES Life Science exam is part of the endorsement process to teach life science in the state of Texas. This test is computer-administered, consists of 100 multiple-choice questions and is subdivided into six domains. The Scientific Inquiry and Processes (SIP) domain accounts for about 15% of the test and will likely cover some material pertaining to laboratories.
In the SIP domain, you are likely to encounter questions assessing, among other things, your ability to use current sources for lab safety regulations and guidelines; recognize potential lab safety hazards and respond to accidents with basic first aid and other safety procedures; design and implement appropriate rules for maintaining a safe learning environment; select and maintain safe chemicals, tools, materials, specimens and equipment; recycle and reuse laboratory resources properly for safe conservation; treat organisms ethically; use equipment and technology appropriately for gathering, organizing and communicating scientific data in a variety of ways; perform calculations for statistical measurement and analysis and calibrate devices.
Our chapter topics correlate with these test objectives. Use the lesson quizzes and chapter exam to get a feel for the types of questions you might encounter on the test. We know you want to arrive on test day feeling confidently prepared and we'd love to help you accomplish that!
1. Common Laboratory Equipment: Types & Uses
Biologists use all kinds of equipment in their labs to run their experiments. In this lesson, you'll identify some of the most common pieces of equipment as well as when you should or shouldn't use them.
2. Laboratory Safety Techniques: Protecting People and Equipment
Laboratory safety is not fun, but following the rules ensures that lab activities can be enjoyed by everyone. In this lesson, we cover some basic lab safety rules to follow that will help lab time be both safe and fun.
3. Standard Laboratory Safety Equipment
Even with proper precautions, lab accidents do happen. When they do, knowing what safety equipment is in your lab, where it is located, and how to use it can prevent further harm to both the lab and the people working in it.
4. Handling Laboratory Solutions, Chemicals & Biological Materials
Working in a laboratory requires careful attention, both for safety and successful completion of tasks. Learn about the many ways biological and chemical substances need to be properly prepared, identified, stored, dispensed, and disposed of.
5. Microscopy Types & Applications
What is microscopy and how do we use it? Learn about the different types of microscopes and the ways we use them for practical purposes. You can then take a quiz and test what you've learned.
6. Techniques to Maintain Data Integrity from Scientific Instruments
In order to be a good scientist, you have to make sure that your data is worthwhile. But how can you be sure of that? This lesson goes over many of the techniques you can use to be sure that your data is both accurate and precise.
7. How to Preserve, Stain & Mount Microscope Specimens
Microscopes are incredible tools for observing the tiniest of organisms. Here we will identify the types of slides that can be made and describe how to best preserve, stain, and mount specimens. At the end, you can test yourself with a brief quiz.
8. Dissection Techniques & Alternatives
In this lesson, we'll talk about the importance of dissection, and hopefully about how to enjoy it! We'll introduce some safety rules and tools, and alternatives to dissection as well.
9. The Ethics of Biological Studies With Living Organisms
In this lesson, you'll learn about some general ethical considerations that must be taken when procuring and treating animals used in biological studies. Afterward, take our quiz to see what you've learned.
