Wash the foam down the sink after the experiment. This means the foam is simply soap, oxygen and water. Normally this breakdown happens very slowly. Fluoride is also present, which helps to strengthen tooth enamel and prevent cavities. Elephant toothpaste is an exothermic reaction, so the foam will be warm to the touch. When mixed with baking soda and vinegar, it can create a powerful cleaning solution. If not, head over to Steve Spangler Science or Science Bob and check it out RIGHT AWAY! Some filters moved to Formats filters, which is at the top of the page. I decided to check out my toothpaste; a well known brand, to see what was in it.

If you want to add color, now is the time. How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide. This slide deck will walk you through a complete lesson and recipe to conduct the "Elephant's Toothpaste" experiment with upper elementary-aged students. But is it safe? Perfectly safe to touch and explore! What is the equation for elephant toothpaste? The kid-friendly version uses chemicals that are safe for children to touch, in case of a splash. When you touch elephant toothpaste, a physical and chemical reaction occurs that causes the toothpaste to expand rapidly. 0000000016 00000 n This makes the reaction colossal. In a measuring cupmix together one tablespoon of yeast and three tablespoons of warm water. This is a class favoriete - it is so exciting and has major wow factor. How does the higher concentration hydrogen peroxide change the results? You might be familiar with hydrogen peroxide as an antiseptic used to clean cuts and scrapes, which it does by killing bacteria. Create your free account or Sign in to continue. Place a funnel in the bottle neck. It also breaks down when exposed to light, which is why it usually comes in dark brown bottles. startxref Articles with space for Close Reading strategies, interactive notebook templates and detailed lesson plans are included.Nearly 70 pages of lesson plans, posters, lab sheets and assessments: Introduction to Matter Matter Mystery (What are the 3 types of matter) Zooming In (How are the 3 types of matter different? The second touch experience is with the foam. Please be aware the concentrated hydrogen peroxide (greater than the household 3%) is a strong oxidizer. Wear gloves, goggles and a lab coat at all times. I do think its time we all started hitting the big toothpaste manufacturers with demands for environmentally friendly ingredients and greener packaging. Measure 1/2 cup of hydrogen peroxide, and carefully pour it into the bottle. WebAn Investigation of Supersaturated Solutions Making rock candy is a safe way to introduce students to solutions and crystal growthand you can What effect does it have on the reaction? In this grades version, students are introduced to chemical reactions including: chemical equations, exothermic and endothermic reactions, reactants and products. How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide. All you need is some hydrogen peroxide, dish soap, dry yeast, and warm water. Into the flask add 150 mL of Hydrogen Peroxide, a tablespoon of dish soap (after a few tries we just used a squirt of dish soap, it doesnt need to be exact), and about 15 drops of food coloring (if desired). Experimental Report Or visit our YouTube channel to see if the video has been uploaded there. How does elephant toothpaste work? Sodium in Water Chemistry Demonstration. On the other hand, organic toothpaste is made with all-natural components that are kinder to teeth and gums. As with the above experiment, the soap foam is soap foam no peroxide is left so it is safe to handle once it has cooled. Normally it comes in a dark bottle because H2O2 or hydrogen peroxide breaks down in light, turning into oxygen (O2) and water (H2O). Food coloring can color the film of the bubbles so you get colored foam. It gets its name from the fast-moving foam produced, which looks like a giant tube of toothpaste being squeezed. Use an infrared no touch thermometer to measure the exothermic reaction. This download makes science easy! When you are ready to do the demo, pour the yeast mixture into the bottle. Stick with the safer 3% hydrogen peroxide you can buy at the drugstore. Students will collect evidence to complete a data chart.. 3. Are you a special education teacher looking to incorporate a fun science lesson? In a separate container, mix a packet of active yeast with a little warm water.
