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
Working in a laboratory requires the use of specialized equipment. Learn about the common laboratory tools used for taking measurements, heating equipment, and performing dissections, and understand how to properly examine lab equipment.
2. Laboratory Safety Techniques: Protecting People and Equipment
Laboratory safety techniques include personal body protection, proper use of containers and substances, protocol for accidents and spills, clean up, and common sense. Explore these techniques for protecting people and equipment while in a laboratory.
3. Standard Laboratory Safety Equipment
Safety is a top priority in laboratories, which must remain stocked with the current, effective, and mandated equipment to keep scientists and others free from harm. Learn about the importance of frequently inspected safety equipment that is easily accessible, and types of needed equipment like fire extinguishers, ventilation hoods, and eye washing stations.
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
Microscopy involves using microscopes to see objects too small to be viewed with the unaided eye. This lesson will explore the different types of microscopy, from electron to optical microscopy, and its applications for learning more about the world.
6. Techniques to Maintain Data Integrity from Scientific Instruments
Discrepancies in measurement or calculation techniques result in less precise and valuable data. Learn different techniques to maintain data integrity by calibrating, measuring accurately, and properly accounting for significant figures with scientific instruments.
7. How to Preserve, Stain & Mount Microscope Specimens
Microscope specimens must undergo the process of staining and mounting before they are inspected with a microscope. Learn how to prepare microscope specimens, the use of slides, the difference between dry and wet mount slides, and the process of staining specimen slides.
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
Ethics is an important component of any study that involves living beings, especially biological studies that pose health and safety risks. Learn what composes an ethical biological study, including proper methods of procurement and treatment.
