Oily Ice
Source Institutions
In this activity, learners experiment with the density of ice, water, and oil. Learners will discover that the density of a liquid determines whether it will float above or sink below another liquid.
Dancing Spaghetti
Source Institutions
In this chemistry activity, learners use spaghetti to explore density and chemical reactions.
Color Splash
Source Institutions
In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.
Layered Liquids: Chemistry You Can Drink
Source Institutions
In this chemistry activity (on page 2 of the PDF), learners make a layered drink with liquids of different densities.
Cauldron Bubbles
Source Institutions
In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.
Red, White and Blue II Demonstration
Source Institutions
In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.
Kimchee Fermentation Chamber
Source Institutions
Learners make kimchee or sauerkraut, which is really just fermented cabbage, in a 2-liter plastic bottle.
