What causes an area to have poor air quality? Use this model to explore the connections between pollution sources, weather, geography, and air quality. Discover which weather condition causes the development of additional air pollutants. Compare the effects of two different pollution sources, pollution-control devices, and changing weather conditions on the air quality over a […]
Create multiple versions of helium atoms and make observations of how changing protons, electrons, and neutrons affect atoms.
Create multiple versions of various atoms and record the number of protons, electrons, and neutrons in a table.
This model allows you to explore why polar and non-polar substances have very different boiling points. While all molecules are attracted to each other, some attractions are stronger than others. Non-polar molecules are attracted through a London dispersion attraction; polar molecules are attracted through both the London dispersion force and the stronger dipole-dipole attraction. The […]
Explore the relationships between properties of molecules, temperature, and movement of particles.
Adjust the initial velocity of a third atom as it hits two bonded atoms and track the changes in energy during this interaction.
Explore what happens when a force is exerted on a ceramic material. There are many different types of materials. Each material has a particular molecular structure, which is responsible for the material’s mechanical properties. The molecular structure of each material affects how it responds to an applied force at the macroscopic level.
Observe how a chemical reaction evolves over time and affects the balance of potential and kinetic energy in the system.
Explore the relationship between charge, electric fields, and forces on objects by manipulating charge.
