Here's a quick and easy science project you can do: make a cloud inside a bottle. This simple project uses water vapor and smoke from a match to help form a cloud.
Dancing Gummi Bear Demonstration
Place a Gummi Bear candy into a test tube containing molten potassium chlorate and watch it dance amidst purple flames. This stunning demonstration is an example of a strongly product-favored reaction, plus it's a lot of fun.
Disappearing Ink Instructions
Learn how to make blue or red ink that will disappear after exposure to air. Tips for restoring the color and an explanation of the acid-base chemistry of the reaction are also included.
Dissolve Styrofoam in Acetone
Dissolving Styrofoam or another polystyrene product in acetone is a spectacular demonstration of the solubility of this plastic in an organic solvent, plus it illustrates just how much air is in the Styrofoam.
Do You Add Sulfuric Acid to Water or Water to Sulfuric Acid?
It's important to add sulfuric acid to water and not water to concentrated sulfuric acid. Here's an explanation of why you don't want to make a mistake and some mnemonics that might help you remember how to play it safe in the chemistry lab.
Endothermic Reaction Demonstration
Here's an endothermic reaction demonstration that is easy to do and cold enough to freeze water.
Experimental Determination of Avogadro's Number
Did you know that Avogadro's number isn't a mathematically derived unit. The number of particles in a mole of a material is determined experimentally. This easy method uses electrochemistry to make the determination.
If you have fruit, a couple of nails, and wire then you can generate electricity to turn on a light bulb. Learn how to make a fruit battery. It's fun, safe, and easy.
Fruit Ripening and Ethylene Experiment
Measure the ripening of fruit from exposure to the plant hormone ethylene by testing starch levels with an iodine solution. This easy experiment can be performed on several types of fruit, such as apples, pears, and bananas.
Gold and Silver Pennies
Take copper pennies and turn then silver, then make them gold. This is an easy chemistry project that uses common laboratory chemicals.
Hot Ice or Sodium Acetate
Sodium acetate or hot ice is an amazing chemical you can prepare yourself from baking soda and vinegar. You can cool a solution of sodium acetate below its melting point and then cause the liquid to crystallize. The crystallization is an exothermic process, so the resulting ice is hot. Solidification occurs so quickly you can form sculptures as you pour the hot ice.
How to Perform a Recrystallization
Recrystallization is a laboratory technique used to purify a sample based on the different solubilites of its components. Learn how to perform a recrystallization and get tips on how to avoid common problems and improve your product yield.
Human Battery Demonstration
Make a human battery by substituting fingers for the salt bridge in a galvanic cell. You can make a human battery with one person, a group of people, or even a thousand people. This is a simple yet impressive electrochemistry demonstration.
Luminol Chemiluminescence Test for Blood
You can use the luminol chemiluminescence reaction as a quick and easy forensic test for blood. Here's a look at what you need to perform the test, how to do it, and an explanation of how the luminol test works.
Mixture and a Compound from Iron and Sulfur
Do you know the difference between a mixture and a compound? Combine iron and sulfur to make a mixture and then react them to form a chemical compound.
Perform the Mohs Test
The Mohs test is one way to determine the hardness of a rock or mineral. You can use the Mohs hardness to help identify an unknown specimen. Here's how you can do the test yourself.
Poinsettia pH Paper
You can make pH indicator from poinsettia flowers, then use the indicator to make your own pH paper test strips.
