What This Document Is
This resource is a set of preparatory exercises designed to accompany the first laboratory session in a General Chemistry I course (CHEM 1110) at Western Michigan University. It functions as a “scavenger hunt” intended to familiarize students with the physical laboratory space, common equipment, and essential safety procedures *before* undertaking actual experiments. The exercises require students to locate and identify key items and understand their proper use, reinforcing foundational lab skills.
Why This Document Matters
This exercise set is crucial for any student enrolled in General Chemistry Lab I. Successfully completing these exercises will build confidence and reduce anxiety when entering the lab for the first time. It’s best utilized *before* your first scheduled lab meeting, allowing you to proactively learn about the environment and equipment. A strong understanding of these preliminary concepts will contribute to a safer and more productive lab experience, and help you avoid common errors during experiments. It’s particularly helpful for students new to a college laboratory setting.
Common Limitations or Challenges
This resource focuses on *identifying* and understanding the *purpose* of lab equipment and procedures. It does not provide detailed instructions on how to perform specific chemical reactions or analyze experimental data. It also doesn’t cover the theoretical background of chemistry concepts; it’s purely a practical, introductory guide to the lab environment. It will not substitute for reading the full lab manual or attending lectures.
