Follow your lunch on an incredible journey with this colourful, ready-to-teach PowerPoint science lesson for Year 4! Children meet their incisors, canines and molars - the cutters, rippers and crushers - and discover why tooth shape matches its job, from lions’ fangs to cows’ grinders. Then it’s off through the digestive system: mouth, oesophagus, stomach, small intestine and large intestine, each explained with bright visual cards and memorable facts (your small intestine is longer than a car!). Two hands-on, interactive activities bring the science to life: a dramatic digestion role-play where groups act out the journey of a food parcel, and planning a classic eggshell “egg-speriment” that teaches fair testing and prediction. Children also learn how plaque and sugar attack enamel and how to keep their smiles healthy for life. Fully matched to the National Curriculum “Animals including Humans” unit, written directly to the child with a friendly cartoon teacher on every slide. Zero prep - just open and teach!
