This short, targeted simulation is adapted from the full-length “Stoichiometric Calculations” simulation.

How many moles of sand grains has the Sahara desert? What is the only equation you´ll ever need in chemistry? The short stoichiometry simulation will help you answer those questions! Follow the footsteps of great chemists and learn about key molecular parameters based on one and only star of chemistry calculations: Avogadro’s Law!

Your first mission in this short simulation is to familiarize yourself with the concept of mole and the way of counting molecules of substances using the one and only Avogadro’s Law. You will learn how to convert huge numbers of particles into handy Avogadro’s number, extensively used by all chemists around the world!

Chemical units relationship

Next, you will explore the relationship between mass, molecular weight, and number of atoms. This magical equation will enable you to perform derivations of molecular quantity parameters for various chemical substances. You will feel like Marie Curie analysing chemical dependencies of chemicals in her french laboratory!

Use theoretical knowledge in practice:

When you learn about those concepts of Avogadro’s number and unit conversion of molecular quantity parameters, jump to the second stoichiometry short simulation “Stoichiometry: Gravimetric Analysis” to use this theoretical knowledge in practice and discover the name of the unknown chemical in the Labster chemistry lab!

Associate Professor
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.”

Lewis Mattin
PhD
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.

Melody McGill
Curriculum Coordinator
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."

Kyle Hammon
Wenatchee Valley College

"The question always is, ‘Can we demonstrate that the students are meeting course outcomes?’ Check! We can do that.”

Dr. Melody Esfandiari
Chemistry Lecturer
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."

Dr. Stuart Goodall
Lecturer
Northumbria University

“The Labster simulations get students to do things, and they're not just sitting there consuming a webinar where their mind can drift. They become an active participant in that learning experience.”

How do students access Labster?

Labster can be integrated within a school's LMS (Learning Management System), and students can access it like any other assignment in their LMS. If your Institution does not choose an LMS integration, students will log in to Labster's Course Manager once they have an account created. Your institution will decide the access method during the sales process.

How is Labster purchased?

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.

How is Labster different from other learning solutions?

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.

What types of courses does Labster support?

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.
