Paper Chromatography

Is artesian water designed to be better, or is it just from wells similar to those in the city of Artesium? This experiment looks at many different types of bottled waters, including artesian. Using a soap mixture, scholars test to see...

Through the analysis of paper chromatography to separate ink from the pen found at the crime scene, learners analyze the different stains and through calculations determine the thief. 

Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

An educational lesson allows young chemists to test the solubility of different types of salt at various temperatures. Groups create a graph using data from unsaturated, saturated, and supersaturated solutions.

Someone stole a diamond-making machine. Who done it? Scholars use forensic science at six different stations to determine the culprit. They analyze fingerprints, use their senses, and complete chemistry experiments to determine the...

Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule. 

The Universal Solvent? Module nine of a 14-part video series involving solids, liquids, and gases is packed full of useful hydration information. The narrator explains such concepts as water solubility, hydrogen bonding, and polarity.

If you don't get along with someone, it's said that the two of you are like oil and water. Why is this? Explore the phenomenon and explain the phrase in one resource! Science superstars first observe samples of oil and water together....

The rules related to solubility of salts are explained in a video that shows the solubility table that summarizes them and concludes with why this information is important to know. 

Want to know a secret? Young chemists may dismiss the idea of needing to test for the presence of water after a chemical reaction,  but when you tell them they can create invisible ink in the process, that might get their attention!...
