If there was an accident in the science lab, would you know what to do? What should you do if your lab partner has a chemical on his or her fingers and accidentally rubbed their eyes? What if your clothing caught on fire? The purpose of this WebQuest is to make you aware of the safety procedures that must be followed in the laboratory setting, and learn to avoid dangerous situations in the lab. Lab experiences give us the much needed hands-on opportunities to learn, but we need to be safe so that everyone enjoys the experience. How do we make sure that our labs are conducted in a safe way?
ESSENTIAL QUESTIONS: What are the critical safety rules that every student should know and why is that important to the physical protection of the entire class? How can a student identify what is hazardous about a particular chemical or science activity that requires special attention for the safety of all involved? How does a graph show the inter-relationship between different sets of data and why is it important to be able to identify trends within graphs? What techniques doe a scientist use to make accurate and precise measurement and why is this so important in any scientific investigation?
GUIDING QUESTIONS: What are the responsibilities of the student when conducting lab investigations? What are the hazards that can result from not following lab safety rules in class? What are some of the topics taught in a physics course and how do they impact your life? How do I construct a graph of data and use that graph to analyze the information it contains?
At the end of this WebQuest you should be able to:
- interpret safety symbols commonly encountered in the science classroom. (1A)
- apply safe practices while performing lab investigations and activities (1A)
- distinguish "safe" behaviors versus "unsafe" behaviors (1A)
- Identify the proper techniques to handle lab emergencies (1A)
- evaluate situations -- what to do "if" or what's wrong (1A)
- pass a written safety test covering safety rules and regulations specific to chemistry (1A)
- dispose of leftover materials and chemicals in a safe and proper manner (1B)
