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.

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.
