Floating Fluids  
In 'Floating Fluids' students investigate the density of various liquids. While students are likely familiar with solids floating in liquids, they may have less experience with one liquid floating on another. If two liquids are insoluble in each other, and are of different densities, one will float in a layer atop the other.

Full of Hot Air  
An empty bottle has its cap removed. The rim of the mouth is moistened, and the cap is placed upside down on the mouth. The bottle is placed in a container of hot water. The cap jiggles and then falls off. ,Just because the bottle looks empty doesn't mean that it is empty. The bottle actually contains air which is made up of different gases. When the bottle is placed in the hot tap water, the heat energy makes the gases in the air expand. The air expands in all directions and pushes against the inside of the bottle, knocking the lid off.

Heat Up and Cool Down  
When heat makes the particles of a substance speed up and spread out, the substance takes up more room. If a substance stays the same weight but takes up more room, it is less dense. In this activity students investigate if less dense hot water floats or sinks in more dense cold water.
