A recent sighting of a blue whale off Tathra inspired the children and educators at Tathra Preschool to investigate just how large the marine mammals are.
Last week the preschoolers watched footage of what was believed to be a blue whale, taken by local surf club member Nick Huggins, leading them to create a "Blue Whale Walk" in their playground.
Over the last few weeks children have been learning fun facts about the blue whale and sharing their learning with their families. They have discovered the blue whale can be 33 metres long and up to 4.5 metres wide (13 metre circumference).
They also found it amazing that the largest animal to ever live on earth eats one of the tiniest creatures.
"Unbelievable" as well was the whale's heart is the size of a small car, their eyes the size of grapefruits and their tongues can weigh as much as an elephant.
Using their environment and outdoor classroom, Tathra preschoolers are learning numeracy and exploring the concept of size through hands-on learning.
They used all their blue whale research to demonstrate the enormous size of the creature in their playground.
The length was created with balance beams and repurposed yellow material. The blue material indicated the width and visual of the whale's circumference.
