A Comparison of Polymeric Liquids with Newtonian Liquids

When life hands you lemons ... experiment on them! Green chemistry gurus compare extraction methods for essential oils through a lab activity. Lab groups use traditional distillation and liquid carbon dioxide extraction methods, then...

Here is the first of four experiments to differentiate among unknown liquids by their behaviors and properties. Pupils observe how different liquids respond to being placed on plastic and paper, and they take notes about their...

Blue-tinted water is added to unknown liquids that have been tinted yellow to find out how they interact. This is a memorable activity that is part of an investigation on the properties of liquids, which is part of a unit on the...

We don't think of liquids as floating typically, but a quick look at any oil spill tells a different story. Lesson explores various densities of liquids and why this fact is important. After observing the density variation, scholars...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation. The...

Liquids are lovely, and this slide show pays them the honor due! It introduces physics participants to the behavior and characteristics of liquids, buoyant force, Archimedes' and Pascal's principles, and the amazing properties of water....

In this fascinating episode, Mr. Spangler uses cornstarch and water to create a solution known as "non-Newtonian" solution, meaning that the solution doesn't behave in the way that Newton's laws would expect it to. This is one of the...

Use class time to perfect your hollandaise sauce with a chemistry lesson. It includes two activities to teach about immiscible liquids, emulsifiers, and creating a stable homogenous mixture. Young scientists first mix liquids in a...

I can get more water to stay on a penny than you can! Collaborative pairs determine the volume of liquids that can be contained on the surface of copper pennies and plastic coins. The pairs analyze their results using graphs and go on to...

In this fascinating episode, Mr. Spangler uses cornstarch and water to create a solution known as "non-Newtonian" solution, meaning that the solution doesn't behave in the way that Newton's laws would expect it to. This is one of the...
