Student Exploration: Archimedes’ Principle
Vocabulary: Archimedes’ principle, buoyant force, density, displace, mass, volume, weight
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. Why does a small pebble sink in water? _Because its density is higher than that of the
water____
_________________________________________________________________________
1. A motorboat is a lot heavier than a pebble. Why does the boat float?
____because the boat is less dense than the surrounding water_______
Gizmo Warm-up
When you place an object in liquid, the downward pull
of gravity causes it to start to sink. As the object sinks,
the liquid pushes back up on the object with a force
that opposes gravity.
In the Archimedes’ Principle Gizmo, you will see how
these forces cause objects to either sink or float.
1. Check that the Width, Length, and Height of the
boat are set to 5.0 cm. Drag one of the green 50-g
cubes into the rectangular “boat.”
What happens? __The boat sank slightly and
water was displaced __
2. Add cubes until the boat sinks. What mass of cubes causes the boat to sink? _150g_
(Note: In this Gizmo, the mass of the boat itself is insignificant.)
3. Click Reset. Experiment with different boat dimensions until you create a boat that holds the
most cubes without sinking.
A. What are the boat’s dimensions? Width: _10g_ Length: __10g__ Height: _10g__
