Molecules and Light

Turn light source on to explore. Observe what happens in the observation window as you set up different combinations of light source and molecule. Note this simulation is the first to support our zoom ...

Molecule Polarity

Hipervinculo Física

Molecule Polarity

When is a molecule polar? Change the electronegativity of atoms in a molecule to see how it affects polarity. See how the molecule behaves in an electric field. Change the bond angle to see how shape ...

Molarity

Hipervinculo Física

Molarity

What determines the concentration of a solution? Learn about the relationships between moles, liters, and molarity by adjusting the amount of solute and solution volume. Change solutes to compare diff ...

Isotopes and Atomic Mass

Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.

Objetivos de Apr ...

Gas Properties

Hipervinculo Física

Gas Properties

Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relati ...

Friction

Hipervinculo Física

Friction

Move the Chemistry book and observe what happens.

Objetivos de Aprendizaje

Describe a model for friction a molecular level

Describe matter in terms of molecular motion

The description should includ ...

Diffusion

Hipervinculo Física

Diffusion

Mix two gases to explore diffusion! Experiment with concentration, temperature, mass, and radius and determine how these factors affect the rate of diffusion.

Objetivos de Aprendizaje

Explain how two ...

Concentration

Hipervinculo Química

Concentration

Watch your solution change color as you mix chemicals with water. Then check molarity with the concentration meter. What are all the ways you can change the concentration of your solution? Switch solu ...

Build an Atom

Hipervinculo Física

Build an Atom

Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!

Objetivos de Aprendizaje

Use the number of protons, neutr ...
