Compare the density of water to that of different liquids. Krystal Balmes and Sahil from the Brooklyn Preschool of Science make predictions about the density of water to that of honey, corn syrup, and ...

Students will be able to explain that the density of a liquid has to do with how heavy it is for the sample size. Students will also be able to explain that if a liquid is more dense than water, it ...

But what does that mean? The simple answer is how heavy something is for its size. If something seems very heavy for its size (like a heavy metal object), we say it is more dense. If something seems ...

The particles of a solid are very close together. It melts when it changes from the solid state to the liquid state. The same mass of liquid will have slightly greater volume than the solid. As ...

Water is so common that we take it for granted. Yet water also has very strange properties compared to most other liquids. In addition to ordinary water and water vapor, or steam, there are at least ...
