The user can draw a compound or choose from a selection of compounds from three databases. Once a compound has been selected the user can click the 2D to 3D button to convert the molecule into a 3D model which is then displayed in the viewer, located on the right side of the screen. In addition to the 3D viewer you can also use the app to distinguish between atomic, molecular, and ionic solids by clicking on the crystallography model tab. What I love about this function of the app is that it helps users identify that each type of solid has different structures and patterns.

A great video about atoms and molecules, using the macaroni salad example.

"This program illustrates the mechanisms of photosynthesis and cellular respiration. It introduces ATP, the universal energy carrier molecules that supply energy-hungry reactions. It also shows the structure and function of Chloroplasts and Mitochondria, energy transforming organelles."

The atoms around you have existed for billions of years -- and most originated in the flaming, gaseous core of a star. Dennis Wildfogel tells the captivating tale of these atoms' long journeys from the Big Bang to the molecules they form today.

"This is a 4 minute HD dramatic video choreographed to powerful music, which introduces the viewer to the wonder of DNA. It is designed as a "trailer" to be shown by Biology teachers in high school and college as a visual "Introduction" to this amazing molecule, and how it has directed all life on Earth."

"Nature's best kept secret is a wonder molecule called RNA. It is central to the origin of life, evolution, and the cellular machinery that keeps us alive. In this Lab you'll play the role of a molecular engineer by solving RNA folding puzzles. Then take your skills to Eterna, where you can design RNAs that could be at the heart of future life-saving therapies."
