Elephant Toothpaste: Science Experiment
In this one-time course, students will learn the basics of chemical reactions by mixing common household items: hydrogen peroxide, dish soap, and activated yeast in order to produce oozing foam that looks like toothpaste!

During this class, students will be led through an exciting science experiment! Before the experiment begins, we will discuss what the students already know about chemical reactions. The students will then mix common household items: hydrogen peroxide, yeast, and dish soap, in a container to produce their own chemical reaction! When the items are mixed together, they produce a foam that oozes out of the bottle. As it is oozing out of the container, it resembles toothpaste being squeezed out of a tube! After we have completed the experiment, we will discuss the basics of what happened in our reaction. The students will learn what a chemical reaction is, what reaction occurred in their experiment, how their foam was produced! The students do not need any prior knowledge in order to complete this class. To instruct this course, I will complete the science experiment with the students in order to model. I also love to create meaningful discussion in the classroom! I have my bachelor's in elementary education, so I am certified to teach all elementary core subjects. I also did 2 internships in 2nd and 4th grade where I taught science classes specifically! I love teaching science because the hands-on learning helps students to learn by discovery!
Learning Goals
The students will learn the basics of chemical reactions through conducting their own experiment.
Other Details
Parental Guidance
The student will be mixing common household items such as hydrogen peroxide, dish soap, and yeast. When we mix the ingredients, a foam will be produced that will ooze out of the bottle. If the student's skin is sensitive to hydrogen peroxide, they will not want to touch the foam that is produced from their reaction. But, if the student is not sensitive to hydrogen peroxide, it is safe to touch! If you would like to help the student measure the ingredients, you can help guide them, but I will also be walking them through the experiment.
Supply List
Needed: 1/2 cup of hydrogen peroxide Dish soap 1 teaspoon of yeast 2 tablespoons of warm water Empty container (I use an empty, plastic water bottle) Cookie sheet or tray to catch the foam Optional: Food coloring Funnel

Hello! My name is Mrs. Kara! I have my bachelor's degree in elementary education, and I have my master's degree in reading and dyslexia. I currently teach kindergarten! I have a passion for teaching and learning! I teach classes for elementary students eager to learn. I believe learning is a gift, and I believe that students learn best through discovery! I love to teach hands-on science courses, themed math classes, and beginning reading courses!
If you do see a class that you would love to take, but it is not offered at a good time for you, please request a time! I will do my best to accommodate your schedule requests!
I want my classroom to be a place of good questions, good discussion, and engaging learning! I love to read, cook, and be outside. I hope to see you in my classroom soon!Reviews
