What is the end result of elephant toothpaste?
Hydrogen peroxide breaks down into oxygen and water. As a small amount of hydrogen peroxide generates a large volume of oxygen, the oxygen quickly pushes out of the container. The soapy water traps the oxygen, creating bubbles, and turns into foam.
What does the elephant toothpaste experiment teach?
Inspire scientific inquiry and discovery with the Elephant Toothpaste Activity. This sensory science experiment is a safe and fun way for teachers to introduce children four years and up to chemical and physical science within small group settings.
What is the hypothesis for elephant toothpaste?
Here, our hypothesis is about hydrogen peroxide. So the experiment needs to change the proportion of hydrogen peroxide in the elephant toothpaste. An experiment also needs a control — a part of the experiment where nothing changes. The control could be no hydrogen peroxide (and no foam).
What is the solution for elephant toothpaste?
Make Elephant Toothpaste Pour 1/2 cup hydrogen peroxide solution, 1/4 cup dishwashing soap, and a few drops of food coloring into the bottle. Swish the bottle around to mix the ingredients. Set the bottle in a sink or outdoors or some other place where you won’t mind getting wet foam everywhere.
What makes elephant toothpaste go higher?
The foam you made in this classic Elephant’s Toothpaste reaction is extra-special because each tiny foam bubble is filled with oxygen. The yeast acted as a catalyst; a catalyst is used to speed up a reaction. It quickly broke apart the oxygen from the hydrogen peroxide.
What kind of chemical reaction is elephant toothpaste?
decomposition reaction
The reaction is an example of a decomposition reaction. Hydrogen peroxide is mixed with some dish soap (and food colouring for effect) and then mixed with either potassium iodide or baker’s yeast mixed with warm water. The hydrogen peroxide decomposes into water and oxygen.
What is the independent variable in elephant toothpaste?
The independent variable is the temperature of the water used. The dependent variable is the foam produced in the reaction. The controlled variable are the amounts of yeast, hydrogen peroxide, dish washing liquid, water, and food coloring that is used.
What is the dependent variable in the elephant toothpaste experiment?
The dependent variable is the foam produced in the reaction. The controlled variable are the amounts of yeast, hydrogen peroxide, dish washing liquid, water, and food coloring that is used.
What causes the reaction in elephant toothpaste?
How does this reaction occur? This reaction occurs when the yeast acts as a catalyst to separate the oxygen from the hydrogen peroxide. The foam is a result of oxygen-filled bubbles from the hydrogen peroxide being broke into water (H2O) and oxygen (O2).
What makes elephant toothpaste explode more?
These bubbles would usually escape from the liquid and pop quickly. But adding a little dish soap provides additional surface tension, allowing the bubbles to get trapped and creating lots of foam. This foam looks like a giant squeeze of toothpaste—almost big enough for an elephant!
