Objective: Children will learn about their teeth and good dental care, and they will perform an experiment about tooth decay.
Note: This experiment will take 2 days to complete.
Our teeth are an important part of our bodies. Our teeth bite and chew our food so it is small enough to swallow. Different teeth have different shapes for the different jobs they do. Some of our teeth are for biting, some are for tearing, and some are for grinding up the food. Everyone has the same types of teeth and they are found in the same spot in each person’s mouth.
Teeth have two parts. The crown of the tooth is the part that we see. The root of the tooth is the part that is below our gum line. The root keeps the tooth anchored in our mouths. The first set of teeth we have are called deciduous teeth. Children have 20 deciduous teeth, which are also known as baby teeth. Around age 6, our baby teeth start getting replaced by our second set of teeth. They start to fall out because they are getting pushed out by the second set of teeth, which are called permanent teeth. When all of our permanent teeth are finished growing, there are 32 permanent teeth.
These lessons are aligned with the Common Core State Standards ("CCSS"). The CCSS provide a consistent, clear understanding of the concepts and skills children are expected to learn and guide teachers to provide their students with opportunities to gain these important skills and foundational knowledge.
