Koodis

Koodis

Meet Koodis, a soft, white sea creature, shaped like a gentle mix of a dolphin and a beluga whale. His bright white color makes him stand out in his blue ocean community and reflects his kind, open, and curious nature.

He loves simple comforts—a cozy nap, a good snack, and time with friends—but he also dreams about what lies beyond home. Small moments often become adventures for Koodis, because his curiosity makes every discovery feel special.

Always wearing his favorite hoodie, Koodis brings warmth, wonder, and quiet joy wherever he goes. He asks questions, explores with childlike excitement, and reminds everyone that adventure can begin anywhere.

Goals & Learning Outcomes

Predictions & Outcomes
Kids practice forming a hypothesis before observing.
Sorting & Classification
Grouping objects by sink/float builds early classification skills.
Pattern Recognition
Kids notice connections between an object's material, size, or shape and whether it sinks or floats.
Recording Observations
Using a simple chart introduces the idea of documenting results for comparison.

Science & Design Concepts

Density

Compares how much an object "weighs" for its size. Objects denser than water sink; objects less dense than water float.

Buoyant force

Water pushes up on every object placed in it. If that push is strong enough to support the object's weight, it floats; if not, it sinks.

Size vs Weight

A big object isn't always heavier "for its size" than a small one. Kids learn that size alone doesn't predict whether something sinks or floats — what matters is the material.

Shape and air pockets

Hollow or air-filled objects (like a closed bottle) float more easily because trapped air lowers the object's overall density.
