It looks like it could be from a giant tube of toothpaste! But adding a little dish soap provides additional surface tension, allowing the bubbles to get trapped and creating lots of foam. Weve used a low strength (3%) which isnt caustic, but can irritate skin and eyes. It is available in different strengths, or concentrations. NOTE: Although we call this toothpaste, it is not toothpaste and should not be tasted.

What is the purpose of the Elephant Toothpaste experiment? A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Step Three Add Try different shaped containers to see how the reaction changes. What is the catalyst in elephant toothpaste? The activity can be done as a teacher demonstration, or working in lab groups. 3. trailer Explore our digital archive back to 1845, including articles by more than 150 Nobel Prize winners. The second touch experience is with the foam. The activity can be done as a teacher demonstration, or working in lab groups. Students are mesmerized by the reaction that takes place and they will ask you to repeat the lab over and over again. 0000002871 00000 n WebShop by Cause. You usually find it in a 3 percent concentration (although higher concentrations are available, they are more dangerous and must be handled carefully). A visit to my toothpaste manufacturers web site didnt reveal any further ingredient information; in fact, the only way I can get information is to call a special number no email, no postal address to receive something back in writing. A clear teacher guide, student pages, and video demonstrations are included. Those gas bubbles would normally pop and disappear, but by adding a bit of dish soap, we can trap lots of bubbles thanks to an increase in surface tension. Complete PowerPoint with Directions, Standards and Objectives, Materials, Student Worksheet, Guiding Discussion Questions, and Video link.This resource, In this heat flow lab, students will determine if the removal of oxygen from hydrogen peroxide is endothermic or exothermic and they will calculate the heat exchanged as well! Answer questions in order to teacher students by using questions 0000002905 00000 n It is made from a combination of hydrogen peroxide and sodium bicarbonate (baking soda), which react to create oxygen bubbles. The lower concentration of peroxide can still discolor fabrics. ) Acting It Out Expan. The dishwashing detergent captures the oxygen that is released, making foam. 0000012588 00000 n All you need is some hydrogen peroxide, dish soap, dry yeast, and warm water. 0000196878 00000 n If you use the standard 3% hydrogen peroxide, then the foam is safe to touch. By clicking Accept, you consent to the use of ALL the cookies. Tooth decay, gum recession, enamel erosion, and other conditions can all contribute to tooth sensitivity.

It As an Amazon Associate I earn from qualifying purchases.Not seeing our videos? Have them touch the sides of the beaker before and after the experiment starts. Getty Images / Andy Crawford and Tim Ridley. This is because the heat produced by the reaction is equal to or greater than the heat lost to the surrounding environment. Its a chemical used in anti-freeze. According to the blog post, elephant toothpaste is safe to touch. Yeast needs warm water to reproduce, so the reaction won't work as well if you use cold water (no reaction) or very hot water (which kills the yeast). Add a big squirt of dish soap into the bottle, and swirl gently to mix. Grades 3-5 focuses on physical and chemical reactions But what is it? Elephant toothpaste is an exciting science experiment for children to learn about chemical reactions. Web2. Procedure. WebElephant toothpaste gets its name from the massive amounts of foam it produces. 0000034010 00000 n We are slowly uploading our archives. In this K-2 version, students practice the steps of the scientific method by changing one of the variables in the experiment, making a hypothesis (prediction), observations, and conclusions. Detergent solution captures gases to form the foam. The foam is safe to touch and play with as a sensory activity, but dont let your children eat it or get it in their eyes. Each of these cute animal pop-up sponges proceeds will be donated to the organization. Measure 1/2 cup of hydrogen peroxide, and carefully pour it into the bottle. Make multi-colored Elephants Toothpaste by dropping different colors of liquid food coloring down the inside of the bottle rather than mixing it into the solution. This means that if you mix yeast with hydrogen peroxide, the hydrogen peroxidewill rapidly break down into water and oxygen gas. Is Elephant Toothpaste a reversible reaction? We would also recommend wearing safety goggles, in case of splashes. (Ive heard 6% hydrogen peroxide can cause skin irritation to those with very sensitive skin.) Maybe a plastic soda bottle or a mason jar with a wider neck. Included: Wear gloves, goggles and a lab coat at all times. Elephant toothpaste is safe to touch after 3 minutes. Its also eco-friendly, which means all of the foam that spilled out into the surrounding vegetation probably didnt harm it. When these two substances come into contact with each other, they create bubbles of oxygen gas that cause the mixture to expand. Hydrogen peroxide is unstable and breaks down over time into water and oxygen gas, but the catalyst potassium iodide speeds up that decomposition into a matter of seconds. No, elephant toothpaste is not hazardous. - Stoichiometry This activity is not recommended for use as a science fair project.
