Say Cheese!
Source Institutions
Create a chemical reaction that makes cheese! This hands-on activity demonstrates that molecules and atoms are tiny particles that make up everything around us.
Chromatography Can Separate!
Source Institutions
In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.
Density: Make a golf ball float!
Source Institutions
In this activity (on page 2 of the PDF), the learner places a golf ball between salt water and colored fresh water. The golf ball is not as dense as the saltwater.
Digit's Cyber-Dough
Source Institutions
In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.
Mystery Powders
Source Institutions
In this activity on page 2 of the PDF (Get Cooking With Chemistry), learners conduct chemical tests on certain powders used in cooking.
Rocket Reactions
Source Institutions
The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.
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.
Toy Chemistry
Source Institutions
In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.
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.
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.
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.
Acids & Bases
Source Institutions
In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.
Shrinkers: Cook up some plastic!
Source Institutions
In this activity (on page 2 of the PDF), learners (with adult help and supervision) investigate how heat affects polystyrene plastic.
Choose Your Ooze
Source Institutions
During this activity, learners will make different versions of "ooze" using varied proportions of detergent and glue.
Invisible Ink
Source Institutions
In this hands-on activity (on page 2 of the PDF), learners experiment with lemon juice and paper to create a message that can only be revealed using chemistry.
The Pressure's On
Source Institutions
In this chemistry activity, learners explore chemical reactions and their effects, including the kind of reaction in the human body that makes people burp!
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.
Polishing Pennies
Source Institutions
In this experiment, learners try different liquids to see which ones clean pennies best. Liquids to try include water, lemon juice, cola, vinegar, and dishwashing detergent.
Sugar/Salt Crystals
Source Institutions
In this chemistry activity (page 1 of the PDF), learners will observe a physical change.
Penny for Your Thoughts
Source Institutions
In this activity, learners will explore how metals react with each other. They will see these metals change before their eyes as they coat a paperclip with the copper taken from a penny.
