Basic Vitamins: Water-Soluble and Fat-Soluble

Why do sharks swim in salt water? Because pepper water makes them sneeze! 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...

In this solubility worksheet, students determine if solutions are unsaturated, saturated, or supersaturated. They use a graph of solubility data to answer questions about the solubility of the three substances graphed.

When environmental studies classes are preparing to sample water for quality, they need to know what factors to test. This collection of slides explains different water quality indicators and why each is important. Viewers will be able...

You are what you eat, right down to your molecular structure. A hearty presentation begins with the two types of carbohydrates, simple and complex. Then it details proteins and amino acids. It ends by reviewing the three types of fats,...

Sal uses the substances, salt, and water to illustrate solubility of a substance. We all know that salt will eventually dissolve in water, but if the temperature is increased, that process happens much more quickly. He explains why this...

What is soap scum, and why does it form? Explore hard versus soft water with a video from JFR Science. The narrator explains why someone might have hard water, the factors that affect ion solubility, and how a water softener addresses...

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.

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. 

The two-day "Vital Vitamins" instructional activity from Do Something, Inc. is all about vitamins. Learners pair up to research a specific vitamin. There are two categories: water-soluble and fat-soluble. They research and write an...

Every cell in the human body contains salt. In an interactive simulation, participants add different salts to water. Some dissolve completely and some are slightly soluble, remaining partially in precipitate form. The number of ions,...
