This document is a lab activity designed for students to explore cell structure and biomolecules, particularly focusing on a mysterious sample labeled Specimen Alpha. The learning objective is to assess students’ baseline knowledge of biomolecules and safety protocols as they prepare for investigations into cellular biology. The lab includes multiple-choice questions addressing cell membrane functions, DNA roles, and enzyme activities within cells. Furthermore, students engage in a predictions section about the function of Specimen Alpha based on their observations and existing knowledge. It incorporates a sorting activity related to different biomolecules, requiring students to match them with their functions, followed by reflective questions that deepen understanding. Additionally, the document stresses the importance of safety in the science lab with specific safety protocols and guidelines for working with chemicals and biological materials.
