We had a BLAST with our dental health unit this past week! Let's get right to it!
On Monday we showed the kids eggs that had been soaked overnight in soda. This is what they looked like.
We talked about how it's important to limit our intake of sodas, coffee and tea and brush our teeth every day so we do not stain our teeth like this egg! We then gave each table an egg and toothbrushes.
We put some toothpaste on each of their brushes and let them go to work!
They had such a great time brushing off the stains. Just remember to use hard-boiled eggs for this experiment or else it could get messy!
Here are is a look at one of the eggs when they were finished.
To close out the lesson on Monday, we had a little discussion about plaque and then dropped one of our eggs in a jar of vinegar. We discussed how the egg was like our tooth and the vinegar was like the plaque that sticks to our teeth. The kids made predictions about what they thought the "plaque" would do to the "tooth".
*We used both hard-boiled and raw eggs for this experiment and the raw eggs definitely worked best.*
When we checked our eggs the following day, this is what we saw.
It's hard to tell from the picture but the shell had been eaten away and the egg was very soft and transparent in some areas. We passed the eggs around for the kids to feel and observe the effects. They then added their conclusions to their recording sheet from the day before.
We decided it was really important for us to brush our teeth every day so our teeth don't end up like the egg! We then gave each kid their own mouth, a toothbrush, and some white paint as toothpaste. They were able to practice brushing their teeth.
The next day we read Gregory, the Terrible Eater and sorted pictures based on whether they were healthy foods or non-healthy foods. I stepped out to complete an observation so I wasn't able to snap any pictures of the activity put here is an example of what it looks like.
If you are interested in any of these activities you can find them in my Dental Health packet on TPT. Click the image below to check it out!
