Flip Teaching on Nutrition

What is Flip Teaching?

In flip teaching, the students first study the topic by themselves, typically using video lessons prepared by the teacher. In class, students then apply the knowledge by solving problems and doing practical work.

Please attempt the following Diffusion and Osmosis homework in the following document:

Homework: Transport in Humans
MCQ: 7,8,9,10
Section B: Q4,
Section C: Q1

To be handed in to Science Rep on CNY Eve. Science Rep please put into Mr Ng’s pigeon-hole outside the staffroom

Homework (to be completed by 4th Feb):
Watch Video on Food Test (posted on blog)
Nutrients – Worksheet Activity 3 (Page 11-12, instructions posted on blog)

Aim: To find out how does your body digests different classes of food
1. Mouth
2. Oesophagus
3. Stomach
4. Small intestine (Duodenum and ileum)
5. Large intestine (Colon)

1. Go to: Digestion in our body
2. Click on the baked beans and find out how your body digests the food.
3. Complete worksheet page 11-12.

This online lesson introduces the various Food Tests:
1. Benedict's test (Reducing sugar test) - Test for reducing suagrs
2. Biuret test - Test for Proteins
3. Ethanol-emulsion test - Test for Fats/Oil




Saturated Fats & Trans Fats

Saturated fats

These fats are derived from animal products such as meat, dairy and eggs. But they are also found in some plant-based sources such as coconut, palm and palm kernel oils. These fats are solid at room temperature. Saturated fats directly raise total and LDL (bad) cholesterol levels. Conventional advice says to Avoid them as much as possible. More recently, some have questioned this, as there are different kinds of saturated fats, some of which have at least a neutral effect on cholesterol.

Trans Fats or Hydrogenated Fats

Trans fats are actually unsaturated fats, but they can raise total and LDL (bad) cholesterol levels while also lowering HDL (good) cholesterol levels. Trans fats are used to extend the shelf life of processed foods, typically cookies, cakes, fries and donuts. Any item that contains “hydrogenated oil” or “partially hydrogenated oil” likely contains trans fats. Hydrogenation is the chemical process that changes liquid oils into solid fats. The tide is turning against trans fats. Since January 2006, all food manufacturers are required to list trans fat content on food labels.
