Learning Logs:EQ: What was the most challenging part of the Marshmallow Lab?A: The most difficult and challenging part of the Marshmallow Lab is constructing three-dimensional structures of molecules, including extended structures and mixtures, using marshmallows and toothpicks to represent atoms and bonds. It is challenging to maintain the structures shape especially when the center of mass in well high above the table such as the structure for diamonds. It is also hard to keep a strong bond of two atoms which can easily result in the molecule(s) splitting into two or breaking apart.
Pure elements are made up all of one kind of atom and atoms in elements do not bond to each other. Atoms share their outer electrons when bonded with other atoms to create molecules. One molecule can have two or more atoms bonded and can be expressed in many ways. Water molecules are always drawn as a bent shape, but carbon dioxide molecules has double bonds and is drawn straight bonds. Subscripts are small numbers equal to the number of atoms bonded in a molecule. Extended Structures are large structures formed as repeating patterns of subunits, for example Salt and forms of carbon. Each capital letter in the chemical symbol is a new element. Diamond and graphite are two very different forms of carbon. Both substances have different structures: diamond structures appear more three-dimensional and strongly bonded, graphite is more flat and has weaker bonds. Mixtures are groups of different molecules that don't bond with each other. Air, carbonated drinks, Kool Aid are some examples of mixtures.
