... the opposite is true. The relative densities of an object and the liquid it is placed in determine whether that object will sink or float. An object that has a higher density than the liquid it's in will ...
... the interactions of liquids and solids. Investigate the relative densities of liquids and the relative densities of solids. Demonstrate an understanding of the relationship between density and buoyancy ...
... flight distance of a toy rocket. Background To make a rocket, you need a container with a pressurized gas or liquid inside. A balloon makes a simple example. When it's inflated, the air inside is ...
... is the force between liquid molecules at the surface of the liquid (in this case water). The water molecules cling to each other, which causes the surface of the water to behave like an elastic sheet. ...

Students explore the melting and solidification of wax. Introduction Students observe wax as it is heated and cooled, and make observations about this substance as it changes from a solid to a liquid, ...
