  1. Lab Safety

  2. Lesson Objectives: • Explain and demonstrate standards for conducting safe laboratory and field investigations. • Identify safety equipment and its use. • Explain how to use safety equipment. • Explain why safety is important in science. • Practice appropriate use and conservation of resources, including disposal, reuse, or recycling of materials.

  3. Essential Question: What tools and safety standards do scientists use in scientific investigations?

  4. Language Objectives: Communicate lab safety procedures with small learning groups using content and academic vocabulary acquired through the use of pre-reading supports such as graphic organizers and visuals.

  5. Standards (TEKS): • 6.1A: demonstrate safe practices during laboratory and field investigations as outlined in the Texas Safety Standards. • 6.1B: practice appropriate use and conservation of resources, including disposal, reuse, or recycling of materials. • 6.4B use preventative safety equipment, including chemical splash goggles, aprons, and gloves, and be prepared to use • emergency safety equipment, including an eye/face wash, a fire blanket, and a fire extinguisher.
