The Science of Water Teacher's Guide provides a number of inquiry-based activities for grades 3-5 (although it can be expanded for other grades). The guide contains science lessons that enable students to explore water, behavior of...

Students observe and discuss water on the molecular level using the idea that water is composed of tiny molecules that are attracted to one another.

This simple lesson plan involves making a model of a water molecule from gumdrops. A toy car is also used to explain how a model compares to the real thing.

Kid's learn about the science and chemistry of water. Molecule H20 and states such as ice, liquid, and vapor.

Students observe and investigate why water has a strong surface tension.

Students investigate how low temperature causes water vapor to condense into a liquid and then freeze to form a solid.

Page uses movies and 3D images to explain how properties of water relate to polarity and hydrogen bonding.

Observe the motion and temperature of water molecules in this simulation as heat is applied to a beaker containing an ice cube.

Discover how the molecular make-up of water affects its density.

Students learn how to create stem-and-leaf diagrams and boxplots by collecting data on the surface tension of water molecules. This hands-on activity using pennies is a great way to learn how to organize data.

One way scientists talk about matter or substance-that is, the stuff in the world-is in terms of pure substances and mixtures. Pure substances are substances that contain only one kind of molecule. Water with nothing else in it is a pure...

Learn how the molecular movement in different temperature water affects the density of the liquid.

Explore surface tension in water by making a paper clip float.
