Let's Investigate with P4.

17th Oct 2019

Primary Four pupils thoroughly enjoyed the eggshell investigation using water and vinegar. They observed the changes to the three eggshells in the different solutions -

A-water only,         B-water and vinegar              and C - vinegar only.

They looked for changes to the eggshells two hours later and then 24 hours later. This helped them understand the impact that plaque acid has on our teeth.
