Good Digestion

Science Year 3/4
This unit is part of Year 3/4 Science The Circle of Life

Objectives

Use your knowledge of the digestive system to play a team game and learn even more about what happens to our food as it travels through our bodies. Begin to work on presenting this information to an audience through narration and dance.

Science Objectives
i) Describe the simple functions of the basic parts of the digestive system in humans

Working Scientifically

  1. Asking relevant questions and using different types of scientific enquiries to answer them
  2. Identifying differences, similarities or changes related to simple scientific ideas and processes

Other Curriculum Areas

English (Yr4s):

  • Compose and rehearse sentences orally
  • Assess the effectiveness of their own and others’ writing and suggesting improvements

You Will Need

Provided Resources

  • Y3 Task sheet - enough copies for groups of 2-3
  • Y4 Task sheets

Additional Resources

  • Pens & pencils
  • Access to the internet and non-fiction books on digestion (optional)
  • A large space for the plenary, e.g. hall or gym
  • A music player with some suitable music to move to (classical orchestral would work particularly well)

Lesson Planning

Teaching

  • To learn and use appropriately the scientific vocabulary of the digestive system.
  • To understand and describe the process of digestion.


Activities

  1. Play a team game to reinforce learning on digestion and extend knowledge further (Yrs 3&4)
  2. Either write a narration script to explain part of the digestive system (Yr4) or solve a matching puzzle to create 8 fascinating facts on the digestive system (Yr3)
  3. Create movement sequences to music that illustrate digestive processes which can be performed during the narrated explanatory scripts (Yrs 3&4)


Investigation
What actually happens to the food? How do the nutrients get into the body? Explore what actually happens with a practical task (exploring, observing)
Year 3- Write a narration script for the mouth and stomach sections of the process using key prompt words
Year 4 – Write a narration script for the small and large intestines


Vocabulary
