Osmosis:
Osmosis is a specific type of diffusion where it mostly relates to the movement of water through a semi-permeable membrane.
The experiment includes filing 3 beakers with the same volume of water. One beaker must be filled with sugar, another one must be mixed with slate and the last one shall be left in its natural state. All beakers will have one gummy bear each.
Hypothesis: I believe that the gummy inside the saltwater beaker will be smaller than its original size. While the gummy bears inside water and the sugary water will expand in size.
Questions:
1. Was your hypothesis correct for each? Two were correct and one was wrong. The gummy bears are inside the slat water and the normal water. my prediction were right. However, I have not taken into the thought that the gummy inside the sugary water would roughly stay the same.
2. Did the bear get bigger or smaller?
Sugary water - Roughly stayed the same
Saltwater - Decreased in size
Water - Enlarged
3. Does that mean that the gummy bear was
- Hypertonic? The gummy bear was hypertonic of glucose, therefore water went inside the gummy hence why it enlarged.
- Hypotonic? The gummy bear was hypotonic of saltwater, hence why glucose went out of the gummy and the size decreased.
- Isotonic? The gummy bear was isotonic to sugary water, meaning equilibrium. This is why there is hardly no change in size.
