Hidden Color Chemistry
Source Institutions
In this activity, learners will discover what colors are in different markers, and may be surprised at the results.
Forgotten Genius
Source Institutions
This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or p
Rocket Reactions
Source Institutions
The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.
Build a Battery
Source Institutions
Learners make a simple battery out of "sandwiches" of aluminum foil, pennies, and a salt water-soaked paper towel.
Egg Osmosis: A four day eggsperience!
Source Institutions
Eggs are placed in vinegar for one or two days to dissolve the shells. Then, learners place the eggs in water or corn syrup and observe them over a period of days.
DNA Extraction
Source Institutions
Learners use a simple process to extract DNA from strawberries.
Bend a Carrot
Source Institutions
In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.
Shaving Cream Marbling
Source Institutions
In this activity, learners will create beautiful greeting cards by marbling with shaving cream and food dye. They will explore the chemistry behind the art of marbling.
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.
Glow Fast, Glow Slow: Alter the Rate of a Reaction!
Source Institutions
Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.
Homemade Bath Fizzies
Source Institutions
In this activity, learners make their own bath bomb fizzies and experience what happens when they mix a base and an acid.
Natural Indicators
Source Institutions
Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).
Changing Colors
Source Institutions
Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.
Disappearing Statues
Source Institutions
In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.
DNA Extraction from Wheat Germ
Source Institutions
DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.
Hot and Cold
Source Institutions
In this activity, learners explore temperature changes from chemical reactions by mixing urea with water in one flask and mixing calcium chloride with water in another flask.
DNA Extraction from Cheek Cells
Source Institutions
DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.
Shrinkers
Source Institutions
In this hands-on activity, learners use heat to shrink samples of polystyrene plastic (#6 recycle code). Learners compare the size and shape of the plastic pieces before and after shrinking.
Salting Out
Source Institutions
In this activity, learners create a mixture of water, alcohol and permanent marker ink, and then add salt to form a colored alcohol layer on top of a colorless water layer.
Diving Submarine
Source Institutions
Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.
