Year 4 Spring Term - 1

Burps, Bottoms and Bile! - Spring Term 1
(Teeth and the Digestive System) 

We’re on a voyage of discovery to investigate the busy world inside your body. Do you have a toothy grin or a winning smile? Take dental impressions and test the effects of sugary substances on your pearly whites. Follow a tasty morsel as it makes its way through your digestive system, helped by some mouth watering saliva. Also, don’t forget the importance of good hygiene at both ends. Whilst we’re talking business, could you recognise an animal just by its poo? Are you brave enough to take the challenge? Make a working model of the digestive system and use it to persuade others to eat healthily. Learn how to look after this marvelous belching, squelching, mixture making machine we call our body. 


How you can help your child prepare for their project

The food we eat goes on an amazing journey through the digestive system. Why not keep a joint food diary for a week to see if you eat enough gut-friendly foods? You could also try a new food or drink that you’ve never tasted before. What do you like or dislike about its taste and texture? Alternatively, drop copper coins into a range of fizzy drinks overnight to see what happens. Which drink has the most powerful cleaning properties?

We will start our new topic by conduct investigations surrounding the human digestive system. We will work collaboratively to label the digestive system using a TEEP style approach. Also, using a range of practical equipment, we will investigate how the digestive system functions using scientific vocabulary 

In English, we will be exploring the book, “Professor Astro Cat’s Human Body Odyssey, to gather knowledge and an appreciation of non-fiction text styles to deepen our understanding of the purpose of informative texts.  We will focus on coordinating and subordinating conjunctions, to enable us to revisit and understand how to build a paragraph whilst deepening the reader’s knowledge. There will be plenty of opportunities to orally rehearse, present and review the effectiveness of non-fiction texts linked to the human body.  

In design and technology, we will learn how to use and make our own levers and linkages through a series of lessons. We will design and make our own moving Christmas card and evaluate the final product. 


At the end of this unit, children will be able to label the body parts associated with the digestive system and identify the different types of teeth and their functions. They will compare teeth with herbivores and carnivores and identify the differences. Children will understand the importance of dental health and the benefits of good oral hygiene and dental flossing, including regular check-ups at the dentist. Children will learn about the characteristics of a poor diet and risks associated with unhealthy eating linked to tooth decay.
