Science Y1 – Healthy habits – week 3
4. Gather again. Tell me one way germs spread. Rob Evans song, “My body is
the temple of the Holy Spirit”. Share this verse and concept.

5. Let's think about our teeth. They are important in our bodies -why?

6. Front teeth - thin and sharp - good for biting.
Back teeth - broad and flat - good for chewing.
They work together to break up food (for a purpose). They are not all the
same.

Encourage the children to examine and count their teeth over the
weekend. [To-do-at-home sheet]

7. Look at the diagram of a healthy tooth. There is more to a tooth than what

we see on the outside.

Bacteria (germs) in our mouths - combine with sugar - to make acid -
which dissolves the tooth enamel.

Set up an experiment. Mark one end of an egg with X and place the other
end in fluoride toothpaste for several days. Then put the egg in a glass of
vinegar (a weak acid). Bubbles should appear from the marked end, but

not from the end strengthened by fluoride, underlining that fluoride
toothpaste can make our teeth stronger to fight acid.

8. Let’s look after the teeth God has given us. Add to the poster after the
lesson.

Learning for Life (Fulfilment)

For the children to acquire healthy habits so that they prove to be responsible
stewards.
