About This Simulation
Have you ever wondered what exactly makes bacteria divided into Gram groups? Do they have special barcodes or tiny identifiers at their surface? Let's find out together!
Learning Objectives
- Differentiate between Gram-positive and Gram-negative cell walls
- Relate the structure of bacterial cell envelopes to Gram stain outcomes

Learn More About This Simulation
This short, targeted simulation is adapted from the full-length “The Gram Stain: Identify and differentiate bacteria” simulation.
Did you know that there are approximately 5 million-trillion-trillion bacteria in the world? Most of them are harmless, some are the cause of serious diseases, but all of them are either Gram positive or Gram negative bacteria. In this simulation, you will explore the structure of bacterial cell walls and learn how to recognise them.
Explore cell wall structures
Discover different structures that build up both types of cell walls and familiarize yourself with their functions. What are the real differences between Gram positive and negative bacteria?
Build your own 3D models
Compare and contrast the cell wall of Gram-positive and Gram-negative bacteria. Play around at the holotable and see if you can replicate the structure of both groups. Test your knowledge on their structures by building your very own bacterial 3D models on the hologram table. Will you be the next Gram and discover a completely new group of bacteria?

For Science Programs Providing a Learning Advantage
North Dakota State College of Science
“They did the simulation at home, then completed the in-person lab within 30 minutes, no questions asked, and passed the quiz with flying colors.”
Lecturer in Human Physiology
University of Westminster
"I saw some of the students who clearly didn’t necessarily like sitting there reading a book discover they could turn on Labster and keep up with the rest of the class because it spoke to them.
Modesto City Schools
"Having something that's engaging for the students gives teachers that opportunity to breathe and get excited again. Because they're seeing the kids light up, they're seeing the kids engage with content."
Wenatchee Valley College
"The question always is, ‘Can we demonstrate that the students are meeting course outcomes?’ Check! We can do that.”
San José State University
"We surveyed over 400 students. More than 90% thought Labster was easy to navigate, and that it was fun, but more importantly, most of them felt confident that they could execute the labs in person. And that confidence is a big deal."

Labster is hosted online, which means that students only have to login from their internet browsers once an account is created.
Labster is only available for purchase by faculty and administration at academic institutions. To procure Labster, simply reach out to us on our website. Schedule a demo, book a meeting to discuss pricing, start a free trial, or simply fill out our contact form.
Labster simulations are created by real scientists and designed with unparalleled interactivity. Unlike point and click competitors, Labster simulations immerse students and encourage mastery through active learning.
Labster supports a wide range of courses at the high school and university level across fields in biology, chemistry and physics. Some simulations mimic lab procedures with high fidelity to train foundational skills, while others are meant to bring theory to life through interactive scenarios.
