Back to School STEM Activity: Lab Equipment & Calibration (BTS9) | Middle School Science Lab Skills (Grades 6-8)

? BACK TO SCHOOL STEM ACTIVITY: LAB EQUIPMENT IDENTIFICATION & CALIBRATION (BTS9)

2-Page Printable STEM Packet | Print-Ready PDF Format

Master core laboratory tools and measurement precision from day one! Lab Equipment Identification & Calibration (BTS9) trains middle school students to act as calibration technicians, learning how to select the right equipment, read liquid meniscus lines accurately, and zero-calibrate digital balances.

Students practice using graduated cylinders, beakers, Erlenmeyer flasks, balances, rulers, and thermometers while calculating net liquid mass and analyzing scale precision limits!

? WHAT'S INCLUDED IN THIS 2-PAGE PACKET?

• ? Page 1: Student Mission Card & Blueprint: Real-world metrology and analytical testing scenario. Clear skill constraints box (Tool matching, meniscus reading protocols, balance tare/zero rules). Dedicated Laboratory Tool Schematics & Meniscus Diagram sketching zone for eye-level meniscus and glassware sketching.

• ? Page 2: Testing Log & Scientific Reflection: Structured Data Testing Table (Equipment audit table linking lab tools to primary functions, scale units, and precision limits). Applied Math Connection (Practice tare mass subtraction equations: Net Mass = Gross Mass - Tare Mass in grams). Scientific reflection questions analyzing volumetric precision, surface tension, and zero-calibration.
