Avogadro's Bubbly Adventure
Source Institutions
In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.
To Dye For
Source Institutions
Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.
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.
Layers of Liquids
Source Institutions
Learners pour equal amounts of coffee, mineral oil, corn syrup, and alcohol into a beaker. The liquids resolve into stacked layers, and learners can infer which liquids are the most and least dense.
Paper Chromatography with Leaves
Source Institutions
In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.
Oil Spill Cleanup
This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.
Swirling Milk
Source Institutions
In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.
Temperature Affects Dissolving
Source Institutions
Learners design their own experiment to compare how well cocoa mix dissolves in cold and hot water. They will see that cocoa mix dissolves much better in hot water. Adult supervision recommended.
Resistance is Useful
Source Institutions
Learners write or draw with white crayon on white paper. They look and feel to detect their marks on the paper. Then, learners paint over their paper with watercolor paint.
All Mixed Up!
Source Institutions
In this activity, learners separate a mixture of pebbles, salt crystals, and wood pieces. They add water and pour the mixture through a strainer.
Dye Detective
Source Institutions
Learners use filter paper and water to analyze six different markers. They mark the paper with ink, and dip the paper in water. The water travels up the paper and dissolved ink travels with it.
