Fun Science: Why Does Orange Juice Taste Bitter After Brushing One's Teeth?

In this one-time class, students will perform a hands-on experiment using the scientific method to understand how different toothpastes affect the way tastebuds react to orange juice.

Class Experience

This class is taught in English.
- Students will learn the six steps of the scientific method.
- Students will perform a science experiment.
- Students will learn about how and why different toothpastes affect one's tastebuds.
- Students will understand the importance of experimentation.
I took Elementary Science as part of my bachelor's degree.
- orange juice (any brand) - toothbrush - ordinary mint toothpaste (with sodium lauryl sulfate [SLS]), such as Colgate or Crest - mint toothpaste without foaming agents (no sodium lauryl sulfate [SLS]), such as Tom's or Hello brands - non-mint toothpaste, such as Colgate Kids - 2 separate cups/glasses of water (one to rinse their mouth; the other for rinsing their toothbrush) - bowl or bucket (to spit toothpaste and rinsed mouth into) I will also provide a handout that students can print and write on or fill out digitally in class.
Learner understanding will be assessed through informal discussions as a class.
30 minutes per week in class, and maybe some time outside of class.
Students will be using three different kinds of toothpastes to conduct the science experiment that you may try to avoid or your kids are not ready for:
1) ordinary mint (with sodium lauryl sulfate [SLS]), such as Colgate or Crest
2) mint without foaming agents (no sodium lauryl sulfate [SLS]), such as Tom's or Hello brands
3) non-mint toothpaste, such as Colgate Kids

Also note that rinsing our mouths and cleaning our toothbrushes can possibly get a little messy, so I would try to have towel nearby just in case.
