Creating the molecules piece by piece is the perfect way to learn their structures visually. Among the basic marshmallow molecules to make are water, carbon dioxide and carbon monoxide.
Wash your hands before opening a bag of multicolored marshmallows and dividing all the different colors into separate piles. There should be four piles: pink, orange, green and yellow.
Assign each of these colors a certain element.
Building Macromolecules Lab Activity, Notes, and Review Questions
For example, the pink marshmallows can represent nitrogen, orange can be oxygen, green can be hydrogen and yellow can be carbon. Study a diagram of the molecule you wish to build. Each molecule is made up of different atoms in varying numbers. For example, a water molecule is shown as H20, which means that it has two hydrogen atoms and one oxygen atom. Take two green marshmallows and one orange marshmallow, which will represent the components of the H2O molecule.
Pierce the orange marshmallow with two toothpicks, each of which point upward and away from each other. Attach a green marshmallow to the open ends of both toothpicks. The structure now accurately represents a water molecule.
Repeat with any molecule you'd like, sticking to the color code and assembling the molecules according to their diagrams.

A special thanks to all of the staff members who have taken the time to help answer these questions. Your efforts are greatly appreciated! Since Jefferson Lab is a nuclear physics research facility, it isn't surprising that we're often asked questions about atoms. We've selected the most common questions from the main archive and have listed them here for your convenience.
What is the difference between atoms and elements? What is the difference between a compound and a molecule? How do I find the number of protons, electrons and neutrons that are in an atom of an element? How many electrons fit in each shell around an atom? How do I read an electron configuration table? Who discovered the element gold, silver, copper, neon, etc? What is one example of indirect evidence that scientists use to study an atom?
What is the simplest way of explaining what atoms, elements, compounds and mixtures are? I am not clear on what a molecule is. If water is a molecule, is it also a compound because the hydrogen and oxygen have been chemically combined? If so What are the components of an atom?
How much does each atom weigh? What is the modern view of the structure of the atom?Embed an image that will launch the simulation when clicked. Starting from atoms, see how many molecules you can build.
