Wimble

Wimble

Wimble is an energetic octopus who loves movement, games, and testing how far he can go.

Quick and agile, he enjoys underwater races and physical challenges where his athletic skills naturally shine. He is always eager to join in, especially when there is something exciting to try.

Although Wimble can lose confidence when things do not go as planned, he never stays discouraged for long. With a little encouragement, he listens, learns, and finds the courage to try again.

His determination and willingness to keep going remind others that progress often comes from not giving up.

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.
