6. Eggcellent Density

Dare to discover different densities! In this activity, students compare floating and sinking and how they relate to density.  Introduction Floating and sinking are due to density. If something ...

7. Floaters and Sinkers

In these activities, students will learn about mass, volume and density and their relationship to each other by conducting investigations in buoyancy—floating (and sinking) objects used in their everyday ...

8. Opposites Attract

... between magnets depends on the separation distance and the flux density (magnetic strength) of the magnets used. Objectives Students will be able to: Explain which parts of a magnet are attractive ...

9. Estuary Connections: Estuary In A Cup

Explore density through investigating properties of water in an estuary. Introduction Saltwater is more dense (heavier), than freshwater because of the salt it contains. When river water pours out ...

10. Kids Under Pressure

In this game, students use their bodies to illustrate how temperature, density, and volume affect air pressure. Introduction Temperature affects how particles move. As air warms up, the particles ...

11. Build a Barometer

... by temperature and density (i.e. how many air particles in a particular space). The Sun heats the Earth unevenly. When air is heated by the Sun, the air particles move faster and expand. This reduces its ...

12. Egg Volume Relay

...  Archimedes was asked by a king to figure out whether the king's crown was pure gold or gold mixed with silver. Archimedes knew that he had to figure out the crown's density: how heavy it is compared ...
