In Science, Year 4 have been learning about our teeth and how to care for them. We conducted an investigation to find out: Do sugary drinks damage our teeth? We used hard boiled eggs as teeth and put them into drinks of; water, cola, milk and orange juice.
Over 1 week we observed and recorded any changes to the egg or drink. We have concluded that “sugary drinks can cause damage to your teeth because the orange juice made the shell rot and peel away” but “you can reduce how much damage it causes by brushing your teeth twice every day and maybe drinking more water”.
