Atoms In Motion, Student Ed. vs CloudLabs Soil Density

Discover the fundamental nature of matter; everything is made of atoms! The atomic theory is brought to life in "Atoms in Motion", and it can be upgraded with an in-app purchase to the full version of Atoms in Motion. In this simulation you control the atoms! "Atoms in Motion" is a fully interactive atomistic simulation that uses sophisticated Molecular Dynamics (MD) algorithms to perform computational chemistry calculations right on your iPad. Such computational simulations reveal the motions of atoms as they attract, repel, and interact with one another to form unique structures and states of matter. "Atoms in Motion" is the ideal App to discover and interact with the physics of chemistry and materials. With the tap of a finger you can easily add, delete, or highlight atoms within the simulation. With a gentle touch you can move, place, or even throw atoms. With the swipe of a finger you can control the temperature and explore the states-of-matter (solids, liquids, and gases). Uncover the physics behind the ideal gas laws, and perform your own experiments by changing the volume, the number of atoms in the simulation, or the temperature. Now as you build and create experiments, you can easily save, manage, and organized them from within the App. The student edition of "Atoms in Motion" uses the same interactive 2-D Molecular Dynamics (MD) simulation as the original, but is limited to 100 neon (Ne) atoms. The Van der Waals forces are computed using a Lennard Jones 6-12 potential, and the simulation continuously computes the pressure. Users can vary the temperature from near absolute zero to over 500K, and add up to 100 neon atoms to the simulation. "There is nothing that living things do that cannot be understood from the point of view that they are made of atoms acting according to the laws of physics" - Richard P. Feynman Enjoy the Atoms!

In this laboratory, the apparent density of different soil samples must be determined in order to establish which is the most suitable for planting a crop. For the development of this practice, a scale, a heating plate, a universal support, and a test tube, among other instruments are available.
