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.
Finding Red
Source Institutions
In this chemistry challenge, learners systematically investigate which combination of four solutions produces a deep red color.
Fizzy Fun
Source Institutions
In this activity, learners test what happens when they put baking power on different frozen liquids.
Physics by the Fire: Matchstick Rocket
Source Institutions
Learners build a small rocket using a matchstick and a piece of aluminum foil. A second, lit match launches the match rocket. This activity involves fire; adult supervision required.
Matter of Degree
Source Institutions
In two separate bags, learners mix water with Epsom salts and detergent.
Exploring Properties: Surface Area
Source Institutions
This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.
Finding Colors
Source Institutions
In this chemistry challenge, learners combine acids and bases in a universal indicator to create five different colors.
Ready, Set, Fizz!
Source Institutions
In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.
Invisible Ink
Source Institutions
In this simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a
Chemical Identification
Source Institutions
In this activity, learners discover how a cabbage juice indicator helps identify acids and bases, and how iodine indicates the presence of starch.
Using Chemical Change to Identify an Unknown
Source Institutions
In this activity, learners will develop a method to test five similar-looking powders (baking soda, baking powder, cream of tartar, detergent, and cornstarch) with four test liquids (water, vinegar, i
Rockets Away
Source Institutions
In this activity, learners build a simple "rocket" with ordinary household materials to demonstrate the basic principles behind rocketry and the principle of reaction.
Powder Particulars
Source Institutions
In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.
Double Replacement Micro-Reactions
Source Institutions
In this chemistry activity, learners use common chemicals to examine reactions that occur between two aqueous solutions.
Production of Carbon Dioxide
Source Institutions
In this chemistry activity, learners use common chemicals to produce carbon dioxide and observe its properties. This resource includes brief questions for learners to answer after the experiment.
Single Replacement Micro-Reactions
Source Institutions
In this chemistry activity, learners use common chemicals and metals to explore single replacement reactions.
Breaking Up with Combustion
Source Institutions
This activity teaches combustion as the interaction of a fuel source and oxygen.
Production of Hydrogen
Source Institutions
In this chemistry activity, learners use mossy zinc (or a galvanized nail) and hydrochloric acid to generate hydrogen gas and test some of its properties.
Comparing the Amount of Acid in Different Solutions
Source Institutions
In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.
Gas Producing Micro-Reaction
Source Institutions
In this chemistry activity, learners use common chemicals and metals to examine reactions that produce gaseous substances.
