We had a busy week learning about our teeth. We learned we must brush, floss and eat good foods so we will have healthy teeth and a beautiful smile.
We practiced brushing!
and flossing!
Our taste test!
We tasted lettuce from our school garden
and broccoli too!
Even the boys liked broccoli...yum!
Our taste test!
And we tasted purple cauliflower from our school garden!
Healthy food is pretty good!!!!
And then we did several experiments!!!
We used Coke and a boiled egg to show how foods can stain our teeth. We learned how important it is to brush our teeth at least 2 times a day. 
We observed the egg all week to see
what would happen...
We used a toothbrush and toothpaste
to clean off the Coke stain!
Brushing and brushing!
Our egg cleaned up pretty good!
The Egg and Vinegar Experiment!
The vinegar caused the shell of the egg to break down and become soft, the same way that tooth enamel is damaged by acid and bacteria in the mouth.
Brushing every day is the only way to keep this from happening.
After a week in the vinegar we observed
what happened to our egg...
It's smelly!
It feels soft!
It's like a rubber egg!
Wow!
Our Apple "Tooth" Experiment!
We used an apple for a tooth model to demonstrate how a cavity forms.
We learned that if bacteria in your mouth creates a hole in the enamel of a tooth, then that tooth will decay and cause a cavity, similar to what happened to the inside of the apple.
