Pneumatic Trough
Source Institutions
In this activity, learners build a "pneumatic trough," a laboratory apparatus used for collecting pure gas samples over water.
Yeast Balloons: Can biochemistry blow up a balloon?
Source Institutions
Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.
pH Scale
Source Institutions
In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.
Watercolor
Source Institutions
In this activity, learners will use chemistry to create a night sky watercolor painting. They will experiment to learn the effects of mixing crayon, salt, and lemon juice with water color paints.
DNA Extraction: Look at your genes!
Source Institutions
Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.
Chemistry is Colorful
Source Institutions
In this activity, learners explore materials through paper chromatography.
Sweetly Balanced Equations
Source Institutions
In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.
