The constant motion of our oceans represents a vast and complicated system involving many different drivers. Sasha Wright explains the physics behind one of those drivers- the concentration gradient- and illustrates how our oceans are...

An extensive list of frequently asked questions about solutions. Dive in and gain better understanding to things like molality and colligative properties throughout the study of solutions.

An account of the role the Majdanek concentration camp in Poland played both in providing labor for the Nazi war effort and in the "final solution" the Nazis planned.

In this limiting reagents problem, students are given specific concentrations of DNA solutions and are asked to predict what products and reactants will remain after a specific volumes are mixed and reaction has occurred.

Teachers can choose from a range of teaching material to present the subject of the Final Solution to students. Materials include lesson plans, archival materials, presentations, testimonies, video lectures, and primary sources.

What happens when sugar and salt are added to water? Pour in sugar, shake in salt, and evaporate water to see the effects on concentration and conductivity. Zoom in to see how different sugar and salt compounds dissolve. Zoom in again to...

In this limiting reagents problem, students are given specific concentrations of DNA solutions and are asked to predict what products and reactants will remain after a specific volumes are mixed and reaction has occurred.

What determines the concentration of a solution? Learn about the relationships between moles, liters, and molarity by adjusting the amount of solute and solution volume. Change solutes to compare different chemical compounds in water.

Students have the opportunity to study examples and worked out example problems to further their understanding of chemical solution concentration.

In this activity, students use the virtual lab to create stock solutions starting from solid salts. Students must first calculate the correct amount of solid to make the solution. Next, they prepare the solution using the appropriate...

Learn the definitions of a solution, solute, and solvent. Understand how molarity is used to quantify the concentration of solute, and comcalculations related to molarity.

What determines the concentration of a solution? Learn about the relationships between moles, liters, and molarity by adjusting the amount of solute and solution volume. Change solutes to compare different chemical compounds in water.

This site provides a brief overview that examines the purpose and operation of German concentration camps during World War II. Suggestions for further reading are also made available. Uses popups.

An interactive simulation that teaches about Beer's Law, solutions, concentration, spectrophotometry, and more through observations to explore how much light is absorbed and transmitted with changes in thickness and color. This...

A moving online exhibit of photographs from an album of a Nazi officer who was the commandant at Auschwitz. The accompanying commentary includes a video, podcast, and comparison of the photos of Nazi officials to those of the inhabitants...

A 20-chapter book on the history of Nazi Germany over the course of the Second World War.

This site, which is provided for by the Purdue University, gives types of solutions, concentration, dilution, and titration.

This lesson will introduce the concept of concentration.

One method of measuring phosphate concentration is by using a Colorimeter. This instrument measures the amount of light transmitted through a sample at a given wavelength.The amount of light absorbed is mathematically related to the...

The problem of protecting food from spoilage has been with us since prehistoric times. The solutions to this problem have changed with advances in technology and knowledge about what causes food to spoil. This project uses liquid...

[Free Registration/Login Required] This flipchart covers the high school chemistry concept of solutions, types of solutions, solution concentration, molarity, percent concentration, Henry's law, solubility, and solubility curve.

Article details the Nazi need for forced labor and the solution they found in the concentration camps they established. It also mentions the use of prisoners in medical experiments.
