6. Steel is 8 times MORE dense than water. How does a steel ship manage to float?

7. 1.Change the Shape

8. Steel is 8 times MORE dense than water. How does a steel ship manage to float? 1.Change the Shape Ships are built with a hollow shape to decrease the density!

10. Steel is 8 times MORE dense than water. How does a steel ship manage to float? 1.Change the Shape Ships are built with a hollow shape to decrease the density!

11. 1.Change the Shape Ships are built with a hollow shape to decrease the density!

12. 1.Change the Shape Ships are built with a hollow shape to decrease the density! 2.Change the Mass

13. 1.Change the Shape Ships are built with a hollow shape to decrease the density! 2.Change the Mass A submarine uses ballast tanks to increase and decrease the mass. When the mass increases, it sinks.

18. 1.Change the Shape Ships are built with a hollow shape to decrease the density! 2.Change the Mass A submarine uses ballast tanks to increase and decrease the mass. When the mass increases, it sinks. 3.Change the Volume By increasing and decreasing the volume of their swim bladder, a fish keep from sinking. Sharks do not have a swim bladder so they must swim constantly!
