Context

The class were learning about teeth and how to look after them. Having obtained parental permissions, the pupils carried out an experiment using disclosing tablets. Some pupils used the tablets before brushing to look at the amount of plaque, while other pupils brushed their teeth and then used the tablets to see how much plaque remained.

The evidence

A child's handwritten work and two pictures of teeth showing the plaque after using disclosing tablets.

The child has written 'Our tev in vestr gashn' Below a picture of someone's teeth, the child has written 'this is a picture of Miss Mitchell teeth wen we came in. wy our now gowing to see how much plak she hass on her teeth.'

Teacher's notes

Luke independently wrote up what he did and knew it was important to brush his teeth and visit the dentist. He thought it would have been more useful to have before and after photographs of his own teeth and could say how dentists might use disclosing tablets to see how well he had brushed his teeth.

Next steps

  • Consideration of how results could be compared to see if there are any patterns in where plaque tends to build up most.
  • Identifying the cause and effect relationship by researching reasons for the build up of plaque.

Assessment commentary

The evidence shows a link being made between scientific observation and personal health, and includes some technical language. Luke reports on what happens but does not, in his writing, explain how his observations help to reveal the importance of brushing teeth or going to the dentist.
