During Covid-19 partial school closures, Felicity Price was doing some online work about tooth decay with her Year 4/5 (age 8-10) pupils. The children were shown a bar chart detailing the extent of tooth erosion caused by different drinks. They used this information to raise their own questions for further investigation (using egg shells to represent teeth).  They also explained why they wanted to investigate their question and what equipment they thought they would need. To aid engagement online and keep the focus on the science, the recording was kept simple.

Based on the information in the bar chart, I would use this as a starting point to investigate…

If the age of your teeth makes a difference to how quickly they erode.

I would like to investigate two different types of orange juice, one a cheaper brand and the other would be a more expensive brand.

Squash drinks and the effects that occur on teeth when diluted with water e.g. weak squash, strong squash and pure squash.

If we add water to lemon juice, would it make it less acidic?
