Students develop their own water molecule model to help them understand the idea that water has a slight positive charge at one end of the molecule and a slight negative charge at the other.

This comprehensive article provides information about the physical properties of water, the importance of water as an Earth material, the processes and cycles that water undergoes on Earth, its importance to life on Earth, and why we...

This site helps students construct a model of the arrangement of water molecules when present as solid, liquid or gas. Includes background information, lesson plans, links to standards and assessment ideas.

Have you ever wondered what makes water 'bead' up on a freshly waxed car? In this project you'll investigate the chemistry of surface tension by measuring how many drops of water a penny can hold.

See how temperature changes affect dissolving and the molecular bonds in a water molecule.

Explore the water molecule, and understand how it is a polar molecule.

Online biology textbook discussing the chemical nature of water, and the importance of its molecular structure to life. Also discusses at length the organic molecules nucleic acids, proteins, lipids, and carbohydrates.

Explore this animation to learn why water dissolves sugar.

Use this interactive animation to find out about whether or not gases dissolving in water.

Discover the concept that energy transfer and molecular motion cause the change in state from a solid to a liquid. Also compare state changes of water to the state changes of other substances.

Lesson plan in which young scholars design an experiment to determine if different types of liquids affect the amount of dissolution of an M&M candy shell.

Explore the process of condensation as it pertains to molecular movement in water vapor.

Resource provides an explanation of Cell Transport. Includes many practical examples, as well as pictures. Sections include Water and Solute Movement, The Cell Membrane. Cells and Diffusion, Active and Passive Transport, Carrier-assisted...

Media-rich lesson in which students discover that it takes energy to break bonds, and that energy is released when bonds are formed during the process of dissolving. They also determine whether dissolving is either exothermic or...

This resource is an article about the cell membrane, and its role in water and solute movement in and out of the cell.

Making your own bubble solution is fun, but sometimes the bubbles don't seem to work as well as the solutions you buy in the store. In this experiment you can test if adding corn syrup or glycerin to your bubble solution will make it...
