1. What we will do What we will learn 10C 10 Poutū-te-Rangi 2017
Quick quiz and preliminaries
How to start well
Revisit what proteins are and how to test for them.
What proteins are for and how to test for them
List the four main food groups
What the four main groups are
Label a diagram of the alimentary canal
What all the bits are
Fill in a table showing parts of alimentary canal, their function (job) and where they are.
What the main parts are, what they do and WHERE they are
Describe BOTH the physical and chemical breakdown of food in the mouth
That digestion starts as soon as food goes in (at least for starches)
Use our new knowledge to predict results from hypothetical tests on food
What our testing can tell us about the foods we eat.
If time, move on to reproductive system in humans
Where babies come from – but without the juvenile baby stuff.

9. PROTEINS Proteins are NOT used for energy.
Proteins are used to repair injury and to make more YOU (growth)
To test for protein we:
Put Copper Sulfate in (Blue)
Put Sodium Hydroxide in (Clear)
If the colour changes to light purple then we have got protein in there.

31. Physical and Chemical Breakdown (digestion) of food.
The job of digestion is to take BIG lumps of food and break them down, firstly into small bits and then into small MOLECULES. When we have molecules, those molecules can go through the lining of the small intestine into the bloodstream.
