Sandy

Sandy

Sandy is a gentle little starfish with a soft heart and a calm, thoughtful nature.

She notices the small details around her and finds joy in simple moments, like the feeling of fresh water moving by or the quiet comfort of familiar places. Sandy often treasures ordinary experiences that others might overlook.

Sensitive and sentimental, she feels things deeply and openly. When situations become uncertain or a little frightening, Sandy may hesitate at first, but she gently encourages herself with quiet reassurance.

Though she is not naturally adventurous, Sandy’s caring spirit and thoughtful perspective often help her friends appreciate the beauty of slowing down and noticing the world around them.

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.
