Label the teeth worksheet for Year 4 Science.

Problem Description:

The task is to label the teeth in the provided diagram using the words from the word bank: premolar, canine, incisor, molar. The diagram shows an open mouth with labeled sections for upper and lower teeth.

Solution Approach:

1. Understand the Function and Position of Each Type of Tooth:
- Incisors: These are the front teeth used for biting and cutting food. They are located at the front of the mouth.
- Canines: These are the sharp, pointed teeth next to the incisors. They are used for tearing food.
- Premolars: Also known as bicuspids, these are located behind the canines and are used for crushing and grinding food.
- Molars: These are the largest teeth located at the back of the mouth. They are used for chewing and grinding food.

2. Analyze the Diagram:
- The diagram shows two rows of teeth: one on the upper jaw and one on the lower jaw.
- Each row has four types of teeth: incisors, canines, premolars, and molars.

3. Label the Teeth:
- Upper Teeth:
- The first set of teeth (closest to the front) are the incisors.
- The second set of teeth (next to the incisors) are the canines.
- The third set of teeth (behind the canines) are the premolars.
- The last set of teeth (at the back) are the molars.
- Lower Teeth:
- The labeling for the lower teeth follows the same pattern as the upper teeth:
- Incisors (front),
- Canines (next to incisors),
- Premolars (behind canines),
- Molars (at the back).

Final Labels:

- Upper Teeth:
1. Incisor
2. Canine
3. Premolar
4. Molar

- Lower Teeth:
1. Incisor
2. Canine
3. Premolar
4. Molar

Explanation:

Each type of tooth serves a specific function in the process of eating. By understanding their positions and functions, we can accurately label them in the diagram. The incisors are at the front, followed by canines, then premolars, and finally molars at the back.

Final Answer:

\[
\boxed{
\begin{array}{l}
\text{Upper Teeth:} \\
1. \text{Incisor} \\
2. \text{Canine} \\
3. \text{Premolar} \\
4. \text{Molar} \\
\\
\text{Lower Teeth:} \\
1. \text{Incisor} \\
2. \text{Canine} \\
3. \text{Premolar} \\
4. \text{Molar} \\
\end{array}
}
