Where does dissolved sugar go?
Ari saw one cube drop in. After stirring, the water looks clear again. Did the cup lose something—or did Ari's eyes lose the trail?
A balance compares two pans
Add one ordinary block. Watch which side moves.
No sugar or water yet—this is only how to read the tool.
One cluster becomes scattered pieces
The same twelve model pieces change from clustered to spread throughout the cup.
Water separates the sugar pieces. Count these 12 model pieces: all stay inside the cup. Real sugar pieces are too small to see.
Record the starting beam
Same cups. Same water. A cube makes the right pan start lower. We mark that beam angle. Now Ari will stir until the cube is unseen, then compare again.
The right pan begins lower, with one visible cube in its water.
As the cube disappears from sight, what happens to the beam?
Move through the test until the cube cannot be seen. Watch the solid beam meet its recorded trace.
