Students explain how water changes from vapor to liquid with a change in temperature by engaging in this experiment. They use a worksheet imbedded in this lesson to guide their inquiry.

Students study the physical properties of different fluids and investigate the relationship between the viscosities of liquid and how fast they flow through a confined area. Student groups conduct a brief experiment in which they...

Students act as chemical engineers and use LEGO MINDSTORMS NXT robotics to record temperatures and learn about the three states of matter. Properties of matter can be measured in various ways, including volume, mass, density and...

By making oil float on water--with the help of other ingredients--students can create a lava-lite effect.
