|TMIS – Explore the Atoms and Molecules|
Have you ever wondered what would become of a drop of water if it is cut over and over again until it cannot be divided anymore?


The children in the Upper Class (9-12 years old) studied the “Atom Theory” last week. We cut out yarns 100, 10, 1, and 0.1 centimeters long and lined them up to feel how small nanometers and picometers are! Our world is constructed of such tiny things called “atoms”!


Then the children learned briefly about the great heroes including Dalton, Thomson, and Rutherford, discussed their theory of the construction of atoms, and how they proved their theory through various ways and experiments. One child said, “Rutherford is brilliant! He proved that his teacher Thomson was wrong!”


Next, the children used straws, styrofoam balls, and styrofoam glue to stick the atoms together and make some kinds of molecules: oxygen, water, carbon dioxide, methane, benzene… etc. One child was surprised, “Carbon dioxide introduces its construction with its very own name! It is consisted of carbon and dioxide!”


The teacher asked, “Do you see that the atoms will form different shapes? In fact, even with the same atoms, they will become totally different things with different constructions. For example, the pencil, which is the graphite, is formed with carbons in the shape of hexagons; the diamond, which is the adamas, is formed with carbons in the shape of methane.”


“In 1985, some scientists found that 60 carbon atoms can form the carbon-60, also called Buckyball. Now, would you like to make one with straws?” Some children really spent two to three days to persistently make a Buckyball with different kinds of materials. A child who studied the nanomaterials even said that he wanted to make a model of carbon nanotube.


This activity combined the characteristics of the 6-to-12-year-old children by Montessori: Love of studying gigantic and tiny things, hero worship, collaborative works, imagination, and reasoning mind. This is not merely a science class. It combines math, history, and art, which is the core of cosmic education. Even though the children may not grasp every concept, we hope to plant seeds in their hearts via discussions and operations and wait for them to flourish in the future at the proper time.
