Lesson details

Key learning points

  1. Scientists make careful observations to investigate which drinks are harmful to teeth.
  2. Scientists review data collected from observations and write conclusions.
  3. In a conclusion, scientists often refer to earlier predictions of what they thought was going to happen.
  4. Too much sugar in food or drink can damage teeth. Information about sugar content in drinks can be found on packaging.
  5. Scientists often present data in a graph to help explain their conclusions to other people.

Keywords

  • observations - We make observations when we look closely at something and use other senses too.

  • Data - Data is information collected during an investigation. It may be numbers, symbols, pictures or text.

  • Conclusion - In a conclusion, scientists explain what the results show or mean.

  • Sugar - Sugar is used to flavour food and drinks to give them a sweet taste.

  • Graph - A graph is a visual way to display results to make them easy to understand.

Common misconception

May believe diet drinks are good for teeth as they don't have sugar in them.

As children observe the eggshells left in different drinks, they will see that diet drinks can still cause tooth decay and discolouration.

Need to have left the eggs in the liquids from the previous lesson for at least 5 days to see appropriate changes.
