[What is ginger?]

Ginger is a plant with leafy stems and yellowish green flowers. The ginger spice comes from the roots of the plant. Ginger is native to warmer parts of Asia, such as China, Japan, and India, but now is grown in parts of South American and Africa. It is also now grown in the Middle East to use as medicine and with food.

[How does it work?]

Ginger contains chemicals that may reduce nausea and inflammation. Researchers believe the chemicals work primarily in the stomach and intestines, but they may also work in the brain and nervous system to control nausea.

Iodine and Starch Experiment | Iodine Experiment | Starch Experiment | Science experiments for kids

Simple and easy experiment to demonstrate the iodine with starch reaction!

For this test you will need:
• Two test tubes
• Soluble starch powder
• Iodine solution
• Water
• Dropper
Procedure:
• Put some starch powder into a test tube and fill the test tube with water.
• Mix the starch in the test tube well until the starch dissolves in the water.
• Fill the other test tube with normal water.
• Place both the test tubes in a test tube stand.
• Using a dropper take iodine solution.
• Put some drops in each test tube.
• Observe that the test tube with starch solution turns to purple black color.
• The other test tube with normal water retains the color of iodine i.e orange or yellow.
Explanation:
Starch is a mixture of amylose and amylopectin, which are different forms of glucose/starch.
Amylose in starch is responsible for the formation of a deep blue black color.
Amylase is long polymer chains of glucose units connected by an alpha acetal linkage and looks much like a coiled spring.
However iodine is a potassium iodide reagent and it is not very soluble in water.
So, iodine is prepared by dissolving it in water in an aqueous solution of potassium iodide. This results in a linear tri-iodide ion (I3−) complex in iodine which is soluble.
This tri-iodide ion (I3−) slips into the coil of the starch causing an intense or deep blue-black color.
