About This Simulation
Join Dr. One in a spaceship and delve into the Earth’s history. Learn about the major events which caused dramatic changes to the composition of the atmosphere, and explore the theories and evidence which surrounds them.
Learning Objectives
- Broadly evaluate theories about the early composition of Earth's atmosphere and how it formed
- Recognize and explain general atmospheric composition stability and change over geologic time
- Detail the current composition of the earth's atmosphere and why this is important to modern life

Learn More About This Simulation
The carbon dioxide-rich, oxygen-deprived atmosphere of the early Earth was very different from our modern-day atmosphere. In this simulation, you will learn about the Earth’s atmospheric composition, how it has changed over the last 4.6 billion years, and its importance for sustaining life.
Explore the theory and find the trends!
The Earth was once a hostile environment with an atmosphere deprived of O2, so where did the oxygen come from? With our hi-tech spaceship, you will be able to collate theories and data to simulate the Earth’s past, taking you back billions of years before life evolved. You’ll explore major events which changed the Earth’s atmosphere, such as periods of high volcanic activity, the forming of the oceans, the evolution of photosynthesizing cyanobacteria, the Great Oxidation Event, and the accumulation of O2 which led to the Cambrian explosion! You’ll investigate periods of atmospheric changes and stability, and dig into the different sources of evidence, from fossils and stromatolites to isotopes and iron formations!
In an interactive activity, you will identify each major event on an area graph using what you know about the atmospheric composition during that period. You will be supported by tailored feedback, quiz questions, and detailed theory pages throughout.
Detail the modern-day atmosphere
A malfunction causes a glitch in the system, causing the data for the modern-day atmosphere to corrupt. It’s up to you to input the correct atmospheric composition into the computer and fix the simulation.
Restore the simulation
Use the knowledge you have learned whilst exploring the Earth’s past atmospheres to correctly input the composition of our modern-day atmosphere. Can you restore the simulation so we can return to modern Earth?

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."
