Page 1
Jun folded a foil boat to carry six counting bears across the classroom water tray. The empty boat floated level.
Page 2
Jun placed all six bears near one side. That edge dipped into the water, and two bears slid out.
Page 3
He made taller walls, but the boat still tilted when the cargo stayed on one side. The shape alone did not fix the balance.
Page 4
Jun moved three bears to the left and three to the right. The weight was spread evenly across the boat.
Page 5
The boat floated level but sat low. Jun rebuilt it with a wider bottom and sides, so it could push aside more water before the rim dipped close to the surface.
Page 6
He loaded the six bears evenly again. The wider boat crossed the tray when Jun made a gentle wave with his hand.
Page 7
Jun tried eight bears next, adding one to each side in turns. He stopped when the rim came close to the water.
Page 8
Jun learned that even cargo helps a boat balance. A wider hull can carry more before its rim gets too close to the water.
