Explore! Mars: Inside and Out!
There's more to the Red Planet than its distinctive coloring! Discover the tallest volcano and deepest valley in the Solar System; take an inside look at the planet's interior; and compare Mars to Earth.
Learn more about Mars.
Additional Mars activities are at Life on Mars.
Scratching the Surface
These activities explore the features of Mars and Earth, include experiments to determine how these features form, and discuss what the features suggest about the history of Mars.
Setting the Scene
Compare Mars' surface features Earths’. Teams of "planetary investigators" examine images of volcanos, channels, and craters on Earth and Mars.
Create channel features with flowing water, and use observations to draw conclusions about Mars' geologic past.
Create impact craters and examine the associated features. Observe images of Martian craters and explore how the mass, velocity, and angle of impactors affects the size and shape of the crater.
These activities compare Mars’ volcanos with Earth’s, and explore Mars’ history and what the volcanos tell us about what is happening inside Mars.
Recipe for a Planet
Build edible models of Earth and Mars to compare their sizes and illustrate their internal layers.
Discover which planet is hotter inside - Mars or Earth, by considering the effect of size (volume) on the cooling rate of objects.
Mind Over Mars
Create question cards and use existing ones for a Mars feature board game.
