  2. May 5, 2024 · There are many interesting and fun projects to try, but these 10 chemistry experiments might be the coolest. Whether you want to witness color transformations with copper and nitric acid or create a foam spectacle with hydrogen peroxide and potassium iodide, there's something here to spark curiosity in everyone.

    • Elephant Toothpaste
    • Color Change Chemiluminescence
    • Colored Fire Cool Chemistry Experiment
    • Copper and Nitric Acid Chemistry Experiment
    • Sodium in Water Reaction
    • Chemical Traffic Light
    • Thermite Reaction
    • Dancy Gummy Bear
    • Sugar and Sulfuric Acid Cool Reaction
    • Flower Shop Reaction

    Elephant toothpaste is one chemistry experiment you shouldn’t miss. The experiment produces heaps of foam, which you can color or even form into shapes by using special containers. The classic version is a reaction between sodium or potassium iodide and peroxide. There is also a kid-friendly versionthat is safe for children (and adults) to touch.

    Most likely, you know about chemiluminescence from glow sticks, but there are more dramatic reactions you can try. For example, there is a cool chemistry experiment where you mix together chemicals, add peroxide, and the solution glows red and then glows blue. This experiment illustrates an exothermic reaction and a decomposition reaction.

    Making colored fire certainly qualifies as a cool chemistry experiment. Just choose the chemical for the color you want. Some of the chemicals are appropriate for making colored fire spray bottles, too. In addition to looking awesome, colored fire demonstrates the emission spectra of ions.

    The copper and nitric acid experimentis as easy as it gets, but it produces dramatic results that illustrate the metal activity series and coordination complexes. All you do is drop a piece of copper into nitric acid. The liquid changes from clear to blue-green and the reaction releases bubbles of reddish-brown vapor. Eventually, the liquid changes...

    Sodium and other alkali metals react vigorously with water. The reaction become more vigorous as you move down the periodic table, so mixing sodium and wateris the safest version of this chemistry experiment. You only use a tiny bit of the metal, yet it burns brightly and gives of sparks and flames. Sodium burns with a yellow flame, but other metal...

    The chemical traffic light is one of many color change chemistry demonstrations. It is a redox reactionwhere a solution changes red, green, and amber, like a traffic light. Temperature affects the rate of the color change, so it also illustrates principles of kinetics.

    The thermite reactionis one of the more dramatic chemistry experiments. All you do is mix a metal and a metal oxide and ignite it. But, this is no ordinary fire. The reaction is very bright and extremely hot. It is the burning of metal, so it serves as an example of oxidation, combustion, and exothermic reactions.

    The dancing gummy bear is a chemistry experiment featuring a gummy bear candy “dancing” in purple flames. But, you can use any candy. A related experiment involves dropping a bit of charcoal into a tube of molten potassium nitrate, making the charcoal dance. The project illustrates combustion, oxidation, exothermic reactions, and the flame testfor ...

    The sugar and sulfuric acid reactionhas another name: the carbon snake. This is a dehydration reaction and decomposition reaction that breaks sugar molecules into elemental carbon, carbon dioxide, sulfur dioxide, and water. The result is a steaming column of black carbon rising from its container. The experiment smells of burning caramel and rotten...

    The flower shop or odor of violets reactiondoes not look as cool as some of the other reactions on this list, but it definitely smells the best. The simple reaction involves mixing two common chemicals and applying heat, releasing a chemical that smells like violets. This experiment demonstrates a rearrangement reaction. Another cool effect is the ...

  3. Mar 4, 2024 · Everybody loves chemistry experiments! We’ve rounded up the best activities, demos, and chemistry science fair projects for kids and teens. Try them in the classroom or at home.

    • Covalent Bonds. By engaging in activities that demonstrate the formation and properties of covalent bonds, students can grasp the significance of these bonds in holding atoms together and shaping the world around us.
    • Sulfuric Acid and Sugar Demonstration. Through this experiment, students can develop a deeper understanding of chemical properties, appreciate the power of chemical reactions, and ignite their passion for scientific exploration.
    • Make Hot Ice at Home. Making hot ice at home is a fascinating chemistry experiment that allows students to witness the captivating transformation of a liquid into a solid with a surprising twist.
    • Make a Bouncing Polymer Ball. This hands-on activity not only allows students to explore the fascinating properties of polymers but also encourages experimentation and creativity.
    • Anne Marie Helmenstine, Ph.D.
    • Thermite and Ice. The thermite reaction is basically an example of what happens when metal burns. What happens if you perform the thermite reaction on a block of ice?
    • Briggs-Rauscher Oscillating Clock. This chemical reaction is amazing because it involves a cyclic color change. A colorless solution cycles through clear, amber, and deep blue for several minutes.
    • Hot Ice or Sodium Acetate. Sodium acetate is a chemical that can be supercooled, meaning it can remain a liquid below its normal freezing point. The amazing part of this reaction is initiating crystallization.
    • Magnesium and Dry Ice Reaction. When ignited, magnesium produces a very bright white light—this is why handheld sparkler fireworks are so brilliant. While you may think fire requires oxygen, this reaction demonstrates that carbon dioxide and magnesium can participate in a displacement reaction that produces fire without oxygen gas.
