Events & Programs

Be Curious. Celebrate Earth.

Curiosity springs to life at PacSci. Celebrate the 50th anniversary of Earth Day by planting seeds of wonder and change, all April long.

Get to know your fellow Earth inhabitants, from exotic butterflies to amazingly adaptable rats. Learn about forest bathing and try it out with a trek through our pollinator garden or Mercer Slough nature trails. Join enlightening talks by Earth experts, marvel at the wonders of the world on our monumental IMAX screens, probe pole to pole in the planetarium, and experience the Ice Under Fire live show—most Celebrate Earth events are included with general admission.

There’s something new to discover, explore, and inspire you to love your planet every day of the week.
