Only do this next extension with responsible middle or high school students, and under direct adult supervision Visit the hair supply store and get 6% or higher hydrogen peroxide. While both versions of the reaction may be performed for a young audience, the original version uses concentrated hydrogen peroxide, which is a strong oxidizer, and potassium iodide, which may not be readily available. Welcome to STEAM Powered Family! xb```g```zAX,-{:`%5,&cyS"C'N In late May 2007, a retailer in New South Wales Australia noticed a box of toothpaste on his shelves also containing that chemical. 2. Elephant's Toothpaste. 30% hydrogen peroxide is added to a glass cylinder containing a concentrated aqueous mixture of potassium iodide and dishwashing soap. The iodide ion catalyzes the decomposition of hydrogen peroxide, generating oxygen gas which causes the soap to foam up and shoot up out of the cylinder. The reaction occurs immediately upon the addition of the yeast. Elephant toothpaste is an exciting science experiment for children to learn about chemical reactions. The expansion is caused by a combination of the soap, which is a surfactant, and the hydrogen peroxide, which is a oxidizer. Potassium nitrate is also an aquatic environmental nasty, parabens can disrupt the hormones in animals and so on and so on. It also breaks down when exposed to light, which is why it usually comes in dark brown bottles. If you want to make your foam a single color, add a few drops of food coloring directly into the hydrogen peroxide, and swirl the bottle gently to mix. When the hydrogen peroxide comes into contact with the yeastit starts breaking down into water and oxygen. This simple science experiment is a another erupting science that thrills kids of all ages.

WebThis is an exothermic reaction, so stand back to avoid burns from the heat. This cookie is set by GDPR Cookie Consent plugin. When you touch elephant toothpaste, a physical and chemical reaction occurs that causes the toothpaste to expand rapidly. Students will also witness a chemical exothermic reaction - aka "heat". The foam produced is just water, soap, and oxygen, so you can clean it up with a sponge and pour any extra liquid left in the bottle down the drain. The two mixtures will react together and burst out of the bottle. 0000094931 00000 n 0000165245 00000 n Knowledge awaits. In this activity, students are wowed by the chemical reaction between hydrogen peroxide, yeast, and dish soap when they make elephant's toothpaste - so much foam! None of the ingredients are toxic, but they should not be ingested. The foam is composed of soap, oxygen and water. On the other hand, organic toothpaste uses natural, environmentally friendly chemicals that can be broken down. Watch Yeast Live and Breathe, Dry yeast (found in the baking section of the grocery store), Location for the activity that can tolerate spills (of hydrogen peroxide as well as possibly food coloring), such as a kitchen or bathroomor an outdoor location, Different-shaped bottles or glasses (optional), Put on your safety glasses to do this activity because hydrogen peroxide can irritate your eyes. Yeast, which we use to make bread, is an organism that contains a special chemical called catalase that can act as a catalyst to help break down hydrogen peroxide.
