Science Activity
An Egg-speriment!
Materials: egg, toothbrush, toothpaste, dark soda (like Coke), and a jar or large glass
Materials: egg, toothbrush, toothpaste, dark soda (like Coke), and a jar or large glass
This simple experiment will show how sugary drinks can affect the teeth and why brushing is so important.
Pour the soda into the jar or glass. Place the egg inside the jar so that it’s completely covered by the soda.
Let the egg sit in the soda for 1-2 hours.
Remove the egg from the soda. What does the egg look like now? (The egg should be stained brown.)
Add a bit of toothpaste onto the toothbrush. Pick a dark spot on the egg and gently brush.
Dip the egg in water to wash off any excess toothpaste. What happened to the spot you brushed with toothpaste? Did the color change? How does brushing with toothpaste help clean your teeth?

Materiales: un huevo, cepillo de dientes, pasta de dientes, refresco de color oscuro (como Coca-Cola) y una jarra o vaso grande.
Este experimento sencillo mostrará cómo las bebidas azucaradas pueden afectar a los dientes y por qué cepillarse los dientes es tan importante.
Coloca el huevo dentro de la jarra o vaso y echa el refresco hasta que cubra el huevo.
Deja el huevo remojar en el refresco por 1 o 2 horas
Saca el huevo del refresco. ¿Cómo se ve el huevo ahora? (El huevo debería estar manchado de marrón).
Pon un poco de pasta de dientes en el cepillo de dientes. Escoge una parte oscura del huevo y cepilla suavemente.
Moja el huevo en agua para enjuagar el exceso de pasta de dientes. ¿Qué pasó donde limpiaste con la pasta de dientes? ¿Cambió el color? ¿Cómo cepillar con la pasta de dientes sirve para limpiar los dientes?
