Chemistry Online Lab

TL;DR

A web-based, photorealistic chemistry lab simulator built in Unity to teach essential laboratory techniques—most notably accurate meniscus reading—successfully used by 500+ students for remote and supplemental lab training.

Purpose

Introductory chemistry students often struggle with fundamental lab skills due to:

• limited physical lab access
• time pressure during in-person labs
• lack of visual clarity when learning precise techniques

This project was designed to provide a high-fidelity, repeatable training environment that allows students to practice critical lab operations before entering a physical lab.

Educational Context

The simulator was deployed as part of an online learning workflow, supporting:

• remote instruction
• pre-lab preparation
• skill reinforcement outside scheduled lab hours

Its design prioritizes clarity, realism, and instructional accuracy over gamification.

Methodology

1) Photorealistic 3D visualization

Unity was used to create accurate, photorealistic models of laboratory glassware and instruments, with particular focus on:

• transparent materials
• liquid surface curvature
• lighting conditions that affect visual perception

This visual fidelity is essential for correctly teaching meniscus reading, a skill that depends on subtle optical cues.

2) Meniscus reading training

The simulator guides students through:

• identifying the correct eye level
• recognizing concave vs convex meniscus shapes
• reading volume measurements accurately from glassware

Students can repeat the process multiple times, reinforcing correct technique through visual repetition rather than trial-and-error in a real lab.

3) Integrated lab procedures

Beyond meniscus reading, the simulator integrates full procedural workflows, including:

• spectrophotometer operation
• burette handling and measurement
• step-by-step experimental processes

This allows students to understand how individual techniques fit into broader lab experiments.

4) Web-based deployment

The lab was deployed as a web application, making it:

• easily accessible without local installation
• compatible with remote learning environments
• scalable to large student populations

This deployment choice significantly lowered barriers to adoption.

Results & Impact

• Successfully used by 500+ students
• Improved student confidence with basic lab operations
• Reduced time spent in physical labs correcting foundational mistakes
• Enabled consistent instruction across large course sections

Instructors reported smoother lab sessions due to students arriving better prepared.
