About

At Blue Marble Sims, we believe Earth and space science is the most important science most people will ever take. It shapes everyday decisions about drinking water, weather, and climate, and a solid grounding in it is the best defense against misinformation, from a flat Earth to a faked Moon landing.

We make free simulations and games for middle and high school Earth and space science. Each activity is designed around a specific science standard and includes questions a teacher can assign to a class in a few minutes. Students learn by working with the system directly, such as moving the Moon around Earth, following a carbon atom through the carbon cycle, or digging through layers of rock, and drawing their own conclusions.

The team behind Blue Marble

Hi, I'm Aaron. My wife, Devon, and I bring years of experience in software engineering, the energy industry, geology field work, and teaching high school Earth science. Earth science education is our passion, and we firmly believe it is the most important science for everyday life. Blue Marble Sims is our way of giving back, which is why it is free.

There are no ads and no student accounts, and no data is sold. Details are on the privacy page.
