Tooth Decay Conclusion

It was extremely fun (and quite messy!) completing the second half of our Science experiment. 

 

This week we took the eggs out of the four liquids and observed the changes to each of the eggs. We observed that the egg in water had not changed, the egg in milk had not changed but the milk had, the egg which had been in coca cola - the shell had stained and the egg which had been in vinegar - the shell had disintegrated.

 

Using our findings we then wrote our conclusions. We concluded that the stronger the liquid and it's pH level, the more effect it had had on the egg shell. This showed us the importance of brushing teeth twice a day to remove any food or liquids on our teeth to stop plaque building up and causing cavities.

 

Have a look at our amazing work from Science:

Helping at Home

Ways to help at home

  • Read every day
  • Practise your spellings and common exception words
  • As you read spot the sounds in words, can you find digraphs (two letters that make one sound) and trigraphs (three letters that make one sound)?
  • Count in 2s, 5s and 10s forwards and backwards
  • Learn your number bonds for all numbers to 20 (e.g number bonds to 7 are 1+6, 2+5, 3+4, etc.)
  • Practise telling the time to the hour, quarter past, half past, quarter to and as an extra challenge to 5 minute intervals (five past, ten past etc.)
  • Practise letter formation using the correct pencil grip and develop fine motor skills (peg pressing, picking pasta shells/rice with tweezers)
