Section IV Class presentation you might use
In this unit, we will learn the difference between rice and the starch. First, each student will have a panicle of rice. Put it on a piece of paper. What does it look like? When we peel it, we get rough rice. Does it look the same as the panicle? Observe it and discuss the differences with your classmates.
The embryo of plant seeds contains four parts: a seed shoot, a seed root, a seed axis, and a seed leaf. Compare the different types of rice and make records of your observation.
How does cooked rice taste? What caused the taste of sweetness? Starch is a type of sugar without a sweet taste. But in the process of chewing, it changes into sugar. When you add a drop of iodine into starch, it becomes blue. We can make use of this characteristic to judge whether certain foods contain starch or not.
