Content Videos (Lectures and animations to supplement lessons):

• Buoyant Force & Archimedes Principle
• Relative Density of a Solid
• Applications

Interactives (Online activities for student interaction & practice with content):

• Buoyancy Simulation (When will objects float and when will they sink? Students learn how buoyancy works with blocks. Arrows show the applied forces, and you can modify the properties of the blocks and the fluid)
• Archimedes’ Law of Flotation: Virtual Lab (students find the masses of various objects and then predict if an object will float by comparing the mass of the object to the mass of water that will be displaced by the object)
• Relative Density: Virtual Lab (students can create objects from object properties like mass, volume, and density, and drop these objects in a tube filled with a fluid. In some phases students can choose the density of the fluid themselves, allowing them to discover the interaction between object properties and fluid density. In other phases students can measure the amount of fluid displaced by the object and discover about Archimedes’ Principle)

Games (Online games for students to apply & test their content knowledge):

• Buoyancy Explorer (students play with hundreds of combinations of liquids and solids as you predict what floats and what sinks in this online game)
• Buoyancy: Match Game (Students drag the corresponding terms & definitions/examples onto each other to make them disappear)
• Buoyancy: Terminology Space Race (Destroy the scrolling words by typing in their corresponding term and pressing enter. You may destroy them in any order, but make sure they don’t scroll past the screen)
