Title: The 2019 Pi Day Challenge is Here

The 2019 NASA Pi Day Challenge Is Here!

The excitement of Pi Day – and our annual excuse to chow down on pie – is upon us! The holiday celebrating the mathematical constant pi arrives on March 14. Get the celebration started with the 2019 installment of NASA's Pi Day Challenge – now available!

› Explore the 2019 Pi Day Challenge lesson!

This illustrated problem set from the Jet Propulsion Laboratory's Education Office gives students in grades 6-12 a chance to solve four real-world problems faced by NASA scientists and engineers. This year, students will use their math skills (and pi) to weather through a Mars dust storm, size up a shrinking storm on Jupiter, estimate the water content of a rain cloud on Earth and blast ice samples with lasers! Answers will be available March 15.
