Year 2 - Science investigation - brushing your teeth!

In year 2 we have been learning about being healthy! This week we have been discussing that in order to be healthy you must be clean and hygienic. One way to keep yourself clean is by brushing your teeth!

Today Year 2 investigated the question "Does the amount of time you brush your teeth affect how clean they will be?

Each group were given an sheet with 5 chalk stains on. Each child, using a  toothbrush and toothpaste were give different time intervals to clean the stain - starting at 5seconds and finishing at 2minutes.

Most groups results showed that the longer your brushed for the cleaner your stain became. However some groups found that this was not true. We discussed the reasons why this might have happened.

Joshua explained that this might have occurred because of how hard or gentle you may have brushed your stain.

Therefore we concluded that not only does the amount of time affect how well our teeth are cleaned but how hard or softly you clean your teeth!

Well done Year 2 some good investigating!
