Finn & Franky

Finn & Franky

Finn and Franky are an inseparable pair who love exploring the ocean side by side.

Finn, the thoughtful seahorse, prefers to observe carefully and think things through. He is practical, honest, and often the voice of reason. Franky, the cheerful sea slug, brings energy and curiosity always asking questions, reacting dramatically, and turning everyday moments into something fun.

Together, they spend their time watching the world around them, chatting about what they see, and sharing their own little “commentary” on ocean life. Finn keeps things grounded, while Franky adds humor and excitement, making them a perfectly balanced duo.

Though different in personality, they share a strong bond. Finn looks out for Franky with quiet care, while Franky brings lightness and joy to their adventures.

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.
