Apply knowledge of the interactions between charged particles to guide an object through a maze.
Compare the surface charges on various molecules and explore which atom types tend to cause uneven sharing of electrons.
Explore forces, energy, and electron distribution in the formation of a molecule.
Explore how different elements come together to form bonds and compare changes in potential energy and forces.
Set the initial height of a pendulum and observe how potential, kinetic, and thermal energy change during pendulum swings.
Set the initial position of a mass on a spring and observe how potential, kinetic, and thermal energy change when the spring is released.
When J.J. Thomson first discovered that a cathode ray was actually a particle beam consisting of a stream of electrons, he concluded that these new particles were not just another type of atom. Explore and compare the behavior of electrons vs. charged atoms when they are shot through an electric field of varying intensity.
Explore the structure of various proteins and see how the nonpolar amino acids form the core of many protein structures.
Explore a protein and its components using a simplified representation to see structure; or a view of all atoms to see full details.
Explore the role of size and shape in the strength of London dispersion attractions. While all molecules are attracted to each other, some attractions are stronger than others. Non-polar molecules are attracted through a London dispersion attraction; the strength of the attraction depends on the shapes and sizes of the interacting molecules. The force of […]
