Starch

In the topic "Energy in Food", we learned about photosynthesis in plants, and how excess sugar in plants are turned into starch.

Today we discussed about starch in class. As many of you have questions on starch, I shared with you a list of food that have high starch content, and the function of starch in human bodies.

Please take note that this is extra information for your understanding of starch, and the information below will not be tested in SA1.

Starch breaks down into glucose in your body.

Glucose: 
  • is used as energy for your body
  • absorbs directly into your bloodstream
  • circulates throughout your body in your bloodstream
  • is used to power all of your bodily functions
  • is the main source of energy for your brain and nervous system

Iodine test

These are some of the food that we've seen in class today when we're conducting the iodine test for Activity 1.5 (Energy Workbook page 10).


From this activity, we found out that the wholemeal bread, biscuit, muffin and baby rice rusk all contain starch.

Easy origami box

In conjunction with Earth Day 2016 on 22 April 2016, our school has planned a classroom-based activity for you.

During today's assembly, you will reuse used paper to make a DIY origami box that you can use as a container for the disposal of eraser dust and waste materials.

This short video shows you the instructions to make your own recyclable waste containers.

Iodine test

The presence of starch will change the yellow iodine solution to blue-black in colour.


We will be conducting this interesting experiment on various types of food in class tomorrow.
