The Molecule Lab contains a library of over 500 carefully constructed 3D models that represent a cross section of molecules important to society and that are widely studied in chemistry, biology, geology, physics, and the health sciences.
The organization of this library reflects structural and functional relationships across a broad range of molecule types. And if you can't find the molecule that you're looking for in the Molecule Lab, search and load molecules from a collection of 25 million 3D models available in the PubChem database at the U.S. National Institutes of Health.
What can you do with all of these molecules? Just tap, pinch, drag, and swipe to investigate them using the the Molecule Lab’s many colorful 3D visualization and physics-based simulation tools. Also, take advantage of the multitude of Web resources linked directly in the app.
- New to viewing molecules? Start out in the "Everyday Molecules" section of the Molecule Library and make connections between the microscopic and macroscopic worlds.
- Studying chemical bonding? Load a series of molecules and see how their valence electrons are distributed in 3D space using the Molecule Lab's "3D Lewis Structure" model type. "See" the connection between a molecule's bonding and its 3D shape.
- Learning about polarity? Examine the electronegativities of the atoms in a molecule and then draw a colored surface around the molecule designating its negative and positive charges. Next, make and test a prediction about how the molecule will interact with other molecules in the Live Lab.
- Looking at minerals under a microscope? Dive deeper and explore the Molecule Lab's large collection of mineral crystal structures and build crystal lattices by simply tapping your finger.
Molecules are in constant motion and they interact with each other via electrostatic forces. Put molecules into the Live Lab’s "virtual box" and run simulations that allow you to see these motions and intermolecular forces (dispersion, dipole-dipole, hydrogen bonding). Then perform experiments on the molecules as you vary the composition, temperature, volume and pressure of the simulation.
- Load a model of a sodium chloride crystal (table salt). Build a layer of water molecules around it. Start a simulation and watch as the polar water molecules dissociate the sodium and chloride ions and see how the water molecules orient themselves around the ions.
- (Re-)Discover the gas laws with simulations that vary one or more of the gas law variables, while also plotting the relationships between the variables. You'll be the envy of Robert Boyle as you use the Live Lab to see how the collisions of the molecules with the walls of the box cause a rise in pressure as the box volume decreases (Boyle's Law).
The Reaction Library contains detailed, interactive models that allow you to follow the 3D rearrangement of atoms as reactants turn into products. Drag the reaction slider and see bonds breaking and forming and track the energy changes (heat of formation) as the reaction progresses. Turn on the 3D Lewis Structure model type and see the valence electrons rearrange as the bonding changes.
Reactions span a broad range of reaction types:
|Synthesis||hydrogen + oxygen → water|
|Decomposition||calcium carbonate → calcium oxide + carbon dioxide|
|Single Replacement||iron + copper sulfate → iron sulfate + copper|
|Double Replacement||silver nitrate + sodium chloride → silver chloride + sodium nitrate|
|Hydrocarbon Combustion||methane + oxygen → carbon dioxide + water|
|Multi-step||sodium bicarbonate (baking soda) + acetic acid (vinegar) →
carbonic acid + sodium acetate →
water + carbon dioxide + sodium acetate
Learning with the Atomsmith Molecule Lab
What else can you do with the Atomsmith Molecule Lab? The only limit is your imagination, and that will grow the more you explore. Plus, we've provided a collection of tools to help you learn with the Molecule Lab:
- Onscreen tutorials walk you through the steps of how to use the Molecule Lab to explore a broad range of concepts in general, organic and biological chemistries.
- An exhaustive glossary puts simple, clear explanations of many terms and concepts at your fingertips.
- A News feature links to current news articles about molecules in everyday society and commerce. Read the news, then examine models of the molecules in the Molecule Lab.
Reviews of The Atomsmith Molecule Lab from the App Store
Makes Me Want To Be Back in the Classroom ★ ★ ★ ★ ★
This is just one of several terrific programs that have been produced by Bitwixt. I taught chemistry for 45 years and this program (along with the others) makes me want to be back in the classroom. The Molecule lab gives chemistry what it needs badly, a good way to visualize what so many of us lack the ability to draw on a whiteboard or an overhead projector. This program is loaded with those visualization tools and tons of great information that should be shared with chemistry students. It can be used effectively by the teacher as a teaching tool or the student as a great source of information and review.
