Gummy bear water uptake

INVESTIGATION QUESTIONHow does soaking liquid change a gummy bear's mass overnight?

● ILLUSTRATIVE SCIENCE MODEL
ENGLISH CAPTIONS

Weigh matching bears. The starting mass is the baseline for calculating each bear’s mass change.

01 / SCIENCE

What explains the result?

Gelatin and sugar create a porous food material that takes up liquid; it is not living tissue and is not a faithful cell model.

02 / EVERYDAY CONNECTION

Where does this matter?

Food texture and water movement matter in cooking, candy making, and food storage.

03 / MODEL LIMIT

What should you keep in mind?

Values shown in this visual model are illustrative. Bear recipes and colors differ; weigh before and after, blot consistently, and record real measurements.

MODEL LIMIT

A gummy bear is a polymer gel, not a cell.

Osmosis is commonly taught with this activity, but the candy does not have a living cell membrane. Water absorption occurs through a gelatin-and-sugar polymer network. Use it to observe swelling and compare treatments, then compare its limits with osmosis in cells.
