Measure an orca!


Here's a fun orca activity you can do outside!

How big are orcas compared to where you live? How do they measure up when compared to other whales? Let's find out!

Take the whale lengths below and measure them outside. Start with an orca at 24 ft. (7.3m) long.



Have someone stand on either end and see just how far apart you are!



Use sidewalk chalk to draw lines to mark the lengths of different kinds of whales so you can compare and show others!

Did you know that whales play a vital role in our planet? Whales go to the bathroom at the ocean's surface where phytoplankton live. Phytoplankton are little plants that, when fertilized by whale poop, create oxygen! Since oceans make up around 71% of our Earth's surface, phytoplankton creates over half of the oxygen you breath! As you are out measuring whale lengths and getting fresh air, thank a whale for pooping!

We want to see the whales in your neighborhood!
