10N 10 Poutū-te-Rangi 2017 What we will do What we will learn Quick quiz and preliminaries How to start well Find out 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 What the main parts are, what alimentary canal, their function (job) and they do and WHERE they are 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. 10N – Seating Plan Front of lab - Whiteboard HW item Skills practiced HW booklet pages on skeletal system, muscles and joints, blood and heart, circulatory system Pages 1 - 8 Due Thursday 2nd of March 2017 Time management Knowledge of three systems in the body Jonathan D: “When I first put the bread on my tongue, it tasted bitter however, after a minute it tasted sweet”. Kanoa: “When I put the piece of white bread on my tongue, it took about one minute til I had the sweetness of glucose”. PROTEINS Proteins are NOT used for energy. Proteins are used to repair injury and to make more YOU (growth) To test for protein we: 1. Put Copper Sulfate in (Blue) 2. Put Sodium Hydroxide in (Clear) If the colour changes to light purple then we have got protein in there. PROTEINS Proteins are NOT used for energy.
