Max made a sealed toy submarine from a small plastic bottle. In a shallow tub with Mom nearby, it floated high.
Page 2
He pushed it down, but trapped air made it pop back up. Max needed weight that would stay attached during the test.
Page 3
He pressed one large lump of clay under the bottle. The submarine tipped nose-first and rested crooked at the bottom.
Page 4
Max removed the lump and divided it into four equal pieces. He placed two near the front and two near the back.
Page 5
The submarine sank level but still touched the bottom. Max removed one small clay piece and tried the test again.
Page 6
Now it floated just below the surface. Max nudged it gently, and it returned to a level position in the water.
Page 7
He recorded three results: no clay floated high, four pieces sank, and three pieces hovered. Mom helped him dry everything.
Page 8
Max learned that trapped air kept the sealed bottle light for its size, while clay added weight. Small, balanced changes helped him find the middle point.
