Digestion – year 4

My favourite session to teach. The whole digestive process from gum to bum and from chew to poo! I very quickly get into using the scientific vocabulary, but do allow plenty of time for giggling and squirming. This session is always memorable: I promise.

Meet the Model – I take you through the entire digestive process with the help of life-size model torso Nearly Headless Nic. Key scientific vocabulary is displayed as captions.

Hands On – Bite, chew & digest the food in this low-tech practical. Brief instructions appear as captions. Full instructions for teachers/parents are below.

Full Lesson – The two videos edited together, so that you can run this as one continuous session. There’s a bit of explanation, then the related practical, then the next bit of explanation, and so on.

Here’s a selection of pieces of potential follow-up work. They are tailored to fit the curriculum targets of the specified year group, especially the SPAG ones. They all include answers / solutions on the 2nd/final page. They have been created by me, using the font from Twinkl.

Maths – Fractions & decimals, based on the fact that the large intestine is 1.5m long, and converting between cm & m. 6x tables practice, using villi.

SPAG – Spot 15 SPAG errors in the text. Ten sets of homophones (or near homophones) to choose between to complete the sentences.

Spelling patterns – 10 clues to find words containing /sc/ making the /s/ sound, as in science. 7 examples of adding the suffix /ion/ to verbs to make them into nouns, as in digest -> digestion.

Crossword – Bumper crossword for lots of technical vocabulary after you’ve watched the videos. The clues are in different forms: standard ‘clues’, code to break (A=1 B=2 C=3), mixed up letters to unscramble, fill in the words missing from the paragraph, and some words to just fit in & write your own clue. Page 1 is the blank grid. Page 2 has initial letters for a bit of extra help. Solution is on p3.

Do let me have any feedback, comments or corrections, and let me know how you get on. If you’re happy to send me photos, I’ll update this page to share them with others.
