Adjust amounts of ionic charges in this simulation to see how water molecules react to polar substances in solution.

Learners explore graphing polar equations by hand. The activity has several examples with detailed solutions. The method used to sketch the graph is point-by-point.

Learners explore the Pre-Calculus topic of polar and rectangular coordinates. The activity has several examples with detailed solutions.

Article offers a comparison between a solution, a solute, and a solution and provides examples.

An experiment where polarized light is shone into a solution of sugared water, causing each of the colors in white light to change direction in varying amounts.

This site from the University of Frostburg provides an explanation of the process by which nonpolar molecules dissolve in water.

Students use conductivity meters to measure various salt and water solutions, as indicated by the number of LEDs (light emitting diodes) that illuminate on the meter. Students create calibration curves using known amounts of table salt...

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 tutorial reviews complex numbers, notation associated with complex numbers, and the basic operations involving complex numbers. Topics examined are conjugates and moduli, polar form, exponential form, arithmetic of complex numbers,...

The University of Saskatchewan's Department of Mathematics and Statistics provides high school students with an online tutorial on complex numbers. Students can access accompanying examples within the tutorial. After you can also test...

College-level physics course highlighting electromagnetism. This course also includes a wide variety of other physics topics including lightning, electrocardiograms, metal detectors, and atom smashers, to name a few. Course includes a...

The resource examines vectors and their properties. Topics investigated are vector, vector arithmetic, dot product, and cross product. Class notes, definitions, and examples with detailed solutions are included. The notes are available...

College-level electrical engineering textbook starting from the Coulomb-Lorentz force law on a point charge. Sample problems that reinforce the content are found at the end of each chapter. Includes downloadable excerpts of the textbook...

A lab activity that introduces chromatography using markers, plus water and acetone as the solvents. Students will take measurements to compare the mobile and stationary phases of the inks, and find the polarity of the inks and solvents....

Explore survival strategies of animals in freezing climates. Investigate the role of glucose (sugar solution) when used as an antifreeze and the relationship between temperature and metabolism.

This lesson will provide an understanding of the chemical and physical nature of water. It is 3 of 4 in the series titled "The Properties of Water."

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."

Uncountable times every day "with the merest flick of a finger"each one of us calls on electricity to do our bidding. What would your life be like without electricity? Students begin learning about electricity with an introduction to the...

This lesson provides basic instruction on the major concepts in algebra. Content includes a focus on fractions, units of conversion, complex numbers, quadratic equations, factorization and roots of polynomials, solving equations, systems...

Learners use their own model of a salt crystal and water molecule to show how water dissolves salt. Then, they relate their observations to the structure of salt, water, and alcohol on the molecular level.

Some proteins are soluble in aqueous solutions and some are not. Insoluble proteins can be a problem because the proteins can form large aggregates in solution which are difficult to purify, crystallize, and use in experiments. Compare...
