To finish off our 'animals including humans' science topic, we are investigating tooth decay. In groups of 3, we have to choose 3 liquids to place eggs in to for a period of time. The eggs will represent teeth and we will be observing what happens to the egg after it has been left in the different liquids. Across the class, we chose water, milk, cola, orange juice and apple juice. We had to predict what we thought might happen to the egg and which liquid will have the greatest effect on the egg. We cannot wait to see the results!
