Why did the big science class lose its teeth and say the lesson draft?

Science teaching plan for kindergarten big class: when changing teeth

I. Significance of the activity

When the child grows to 5 or 6 years old, the original deciduous teeth begin to fall off gradually, which will affect the child's permanent teeth for life. If left unchecked, it will often have some bad consequences. Teaching children the knowledge of changing teeth in time can help them adapt to this physiological change as soon as possible and learn to protect their teeth scientifically. Beautiful, neat and healthy teeth will be beneficial to children's future life and work.

2. Introduce the different functions of incisors, canines and molars.

Guide children to talk about their front teeth, canine teeth and molars while eating food. Summary: Anterior teeth are thinner than other teeth, which can cut and bite food, while canine teeth are sharp and long, which can tear food; Molar teeth are wide and thick, which can grind food.

3. Show a wall chart to guide children to compare the number of teeth between adults and children and find out the differences.

4. Guide the children to discuss: Some children have lost their teeth, will they grow back?

5. Introduce deciduous teeth and permanent teeth.

6. Understand the knowledge of tooth change.

Guide the children who have experience in changing teeth to talk about how the teeth fell out and what would happen if they fell out. The teacher told the children that deciduous teeth will fall off when they are 5 or 6 years old, and then they will grow new teeth-permanent teeth. It hurts a little when I lose my tooth. Don't be afraid if you bleed a little. Rinse your mouth with cold boiled water when bleeding, and it will stop. Every child should always pay attention to whether his teeth are loose. If so, they will grow new teeth.
