What is the hypothesis of the elephant toothpaste experiment?
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 purpose of elephant toothpaste experiment?
Ask if your kids noticed the bottle got warm? The experiment created a reaction called an exothermic reaction, which means it not only created foam, it created 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.
What does elephant toothpaste prove?
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.
Is Elephant Toothpaste a chemical or physical reaction?
As a result of a chemical reaction, new substances with new properties are formed. In this lesson, students will learn about physical and chemical changes. Physical changes will be demonstrated with playdough and/or M&M’s Candy. The chemical change will be demonstrated by making “Elephant’s Toothpaste.”
Is Elephant toothpaste safe to eat?
It really does look like toothpaste fit for an elephant, but it is also a fun reaction experiment; one you’ll want to do over and over. Common sense warning: Do not eat or brush your teeth with elephant toothpaste!
What household items can you use to make 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.
- In a separate container, mix a packet of active yeast with a little warm water.
- When you are ready to do the demo, pour the yeast mixture into the bottle.
What is the conclusion for elephant toothpaste?
What is the conclusion of the elephant toothpaste experiment? Our hypothesis stated that the trial using the 30% solution would be the fastest and it was proven correct. It was the fastest because it had more pure hydrogen peroxide making it have more oxygen when broken down and pushing the foam out faster.
Will 3 hydrogen peroxide work for elephant toothpaste?
What is Elephant Toothpaste? This large demonstration uses hydrogen peroxide (H2O2), sodium iodide (NaI) and soap. That is usually 3% hydrogen peroxide, and your local salon probably uses 6%. The 30% hydrogen peroxide is not something you would put on a cut or scrape, but it works perfectly for this demonstration.
What is the best container for elephant toothpaste?
You can easily use the elephant toothpaste reaction as a holiday chemistry demonstration. Just add green food coloring to the peroxide and detergent mixture and pour the two solutions into a Christmas tree-shaped container. A good choice is an Erlenmeyer flask because it has a cone shape.
Does 3 hydrogen peroxide work for elephant toothpaste?
Is elephant toothpaste safe to eat?
What are the procedures for making elephant toothpaste?
Elephant Toothpaste Procedure Put on gloves and safety glasses. Pour ~50 mL of 30% hydrogen peroxide solution into the graduated cylinder. Squirt in a little dishwashing detergent and swirl it around. You can place 5-10 drops of food coloring along the wall of the cylinder to make the foam resemble striped toothpaste. Add ~10 mL of potassium iodide solution.
What is the result of elephant toothpaste?
The original elephant toothpaste reaction, which uses a much higher concentration of hydrogen peroxide, can cause both chemical burns and thermal burns. While it produces a larger amount of foam, it’s not safe for kids and should be performed only by an adult using proper safety gear.
What is the elephant’s toothpaste experiment?
Elephant Toothpaste Experiment Details. Step 1 – Combine two tablespoons of warm water with one teaspoon of yeast and mix until the yeast is completely dissolved in the water. Step 2 – Pour 1/2 cup hydrogen peroxide into the empty bottle.
What do you need for elephant toothpaste?
To make elephant toothpaste you will need: 9% hydrogen peroxide, which is a mild skin disinfectant that you can buy over the counter at pharmacies (Warning: hydrogen peroxide can irritate eyes and sensitive skin, so wear safety glasses and gloves. Do not swallow hydrogen peroxide or splash in eyes.)
