Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

Ever wonder how they solve those mysterious murders in TV crime dramas? The second of four units in a Biotechnology series introduces scholars to the many methods of DNA analysis. Pupils create and run their own gel electrophoresis...

Students examine the topics of ocean waves, currents, and tides. They locate and label ocean currents on a world map, conduct experiments, analyze key vocabulary, view demonstrations and record the data, and complete handouts.

This video/lesson series explains how the structure and behavior of H2O in liquid form gives water its properties, and make it a chemical essential for life. Also in this collection: a Victorian-era depiction of the water molecule; news...

A brief introduction to the molecular structure of a water molecule, and the chemical bonding which gives it its unique properties.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will describe the structure and polarity of a water molecule. They will also describe the hydrogen bonding that occurs in...

In this investigation students will add energy to the model of how molecules interact by completing the following activities. Activity 1 What does boiling do to water molecules? Activity 2 How hot can water go? Activity 3 How does energy...

Activity 1 investigates What does boiling do to water molecules? In this activity students will collect evidence to analyze what happens to water during boiling.

[Free Registration/Login may be required to access all resource tools.] Covers structure of water molecule, hydrogen bonding on water, polarity of water molecule, and bond angles of water molecule.

An audio podcast accompanied by a diagram of a water molecule helps the learner understand molecular structure. [0:23]

Given scenarios, descriptions, or illustrations, the student will determine the properties of water that affect chemical and biological systems.

Activity 2 investigates How Hot Can Water Get? In Activity 2 students analyze the relationship between energy changes and phrase changes as they discuss what happens when water boils. Bonus reading includes Why is Temperature Constant...

[Free Registration/Login may be required to access all resource tools.] Covers the structure and properties of water.

This general tutorial begins with an explanation of the polarity of the water molecule and the effects this polarity has on the properties of water. Goes on to introduce organic molecules and has a thourough tutorial on the third page.

This lesson will provide an understanding of the chemical and physical nature of water. It is 1 of 4 in the series titled "The Properties of Water."

Activity 4 investigates How does electron distribution impact our observations? Students have described how properties of molecules change depending on what atoms make up the molecule. In this activity students will use those ideas to...

An investigation of how polar and nonpolar interactions affect shapes of biological molecules and their function. Modules explore the following: 1. Why don't oil and water mix? 2. Can a substance dissolve in both a nonpolar and a polar...

How does energy charge when evaporation is reversed? and What powers a hurricane? are explored in this module.

This lesson explains the process of osmosis. It explains how osmosis is a passive form of transport, used to move water molecules across a semi-permeable membrane, down their concentration gradient. It is 1 of 8 in the series titled...

In this learning module from The Concord Consortium, students will investigate how polar and nonpolar regions in big molecules interact to result in certain shapes and properties for those molecules.

The purpose of this tutorial is to introduce you to some of the chemical concepts which are necessary to understand biology. Concepts include the basics for understanding biology, chemical bonds and attractive forces, the chemistry of...

How do microwaves heat up your coffee? Adjust the frequency and amplitude of microwaves. Watch water molecules rotating and bouncing around. View the microwave field as a wave, a single line of vectors, or the entire field.
