In Class 4 the experiment was to identify the effects of liquids on our teeth.
We used chalk to represent teeth and experimented to see the effects different liquids had upon the chalk. We used; lemon juice, lime juice, orange juice, water, coke and vinegar.
We discovered that the lime and lemon juice made the chalk disintegrate and dissolve, and the coke made the chalk turn brown.
Key scientific vocabulary we used were: equipment, variables, fair test, liquids, rot, decay, plaque, sugar, teeth, dissolve, fizz, disintegrate, effect, measure, pour, squeeze.
