Young students focus on healthy teeth – and a whole lot more

Pre-K students at The Varnett School East used the topic of teeth-brushing to learn about science, language and math.

In a month-long project on healthy choices, the instruction this week emphasized the importance of students brushing their teeth at least twice a day, flossing and going to the dentist for regular check-ups.

But in a more narrow focus, these 23 students conducted experiments about the damage certain food dyes can have on their teeth.

According to,artificial colors cause a change in the color of the teeth. But the challenge comes from the products they are added to like sweets, candies & aerated drinks. The extraordinary high content of sugar causes bacterial growth and cavities. The stickiness just adds to their harmfulness.”

The Top Drinks and Food That Stain Teeth

In the experiment, students dipped an egg in clean water and other eggs in water containing five colored substances, said Ms. Tesla Villeda, the teacher’s aide. The eggs have been left sitting for two days. The students were then asked if the different color dyes will change the color of the eggs. Yes or no? That question falls into the area of predictability and hypothesis.

“We had fun using big words,” Ms. Villeda said. That’s the vocabulary part. The majority of students predicted the eggs would change color. That’s the math part. The coloration of the eggs is the science part.

Later today, on Feb 1, the students will discuss the results.

This experiment leads to the ultimate question, Ms. Villeda said. “Does brushing your teeth with toothpaste clean your teeth?

So, watch what you eat, brush your teeth, don’t forget to floss and go to the dentist for regular checkups

Class dismissed!
