Teeth - Lesson Plan

The lesson plan from The Primary Science Advisory Service Ltd focuses on educating Year 4 students about the different types of human teeth and their functions. The lesson is structured to enhance various science skills such as observing over time, pattern seeking, identifying, classifying, grouping, and researching using secondary resources. Pupils will delve into the National Curriculum knowledge by learning to identify and name the different types of teeth, describe their functions in relation to their shapes, and discuss dental issues that can arise from poor oral hygiene. This lesson builds on previous learning from earlier years, where pupils explored the basic needs of animals, the importance of exercise, diet, and hygiene, and the role of skeletons and muscles.

During the lesson, students will engage in a series of activities that include researching and classifying teeth, observing the effects of different liquids on eggs (which simulate teeth) to understand staining, and testing the effectiveness of various toothpaste brands against acidic vinegar to mimic enamel protection. They will also investigate the importance of brushing by using plaque reveal tablets and creating a before-and-after comparison. The lesson aims to correct common misconceptions such as the belief that only carnivores have sharp teeth or that tooth loss is permanent in all animals. To support the lesson, cross-curricular links are made with English, Maths, and History, and health and safety considerations are outlined. The lesson concludes with a plenary where pupils assess their understanding of dental hygiene and the functions of different teeth types.
