Featured Chemistry Activities
Atomic Structure
Explore ion formation, isotopes, and electron orbital placement using interactive models of atomic structure.
Atoms and Conservation of Energy
How does the Law of Conservation of Energy (the First Law of Thermodynamics) apply to atoms?
Baggie Chemistry
Household chemicals mixed in a baggie produce dramatic results.
Catalysts
Explore the effects of homogeneous catalysts.
Chemical Bonds
Explore the different kinds of chemical bonds that can form, ranging from non-polar covalent to ionic.
Chemical Reactions and Stoichiometry
Control the concentrations of molecules and temperatures of reactions to explore reaction rate dynamically, and change the ratios of chemicals and observe the effects to learn how to balance chemical equations.
Electrons in Atoms and Molecules
The interactions of electrons with matter are central to many technologies from transistors, diodes, and smoke detectors to sophisticated imaging, lasers, and quantum computing.
Gas Laws
Explore the interrelationships of pressure, temperature, and volume with atomic models of Boyle's Law, Charles's Law, Gay-Lussac's Law, and Avogadro's Law.
Intermolecular Attractions
Explore how London dispersion attraction and dipole-dipole interactions explain the different boiling points of materials and apply that reasoning to DNA, antibodies, and gecko feet.
Making and Breaking Bonds
Explore the association and dissociation of diatomic molecules.
Making Heat
Does change in concentration change the amount of heat released in a chemical reaction?
Melting Ice
What is the temperature of ice as it melts?
Molecular Geometry
Use models of electron arrangement around atoms to discover how molecules form linear, trigonal planar, and trigonal pyramidal shapes.
Phase Change
Explore what happens at a molecular level as substances change phase.
Probability Clouds
Investigate the probability map of electron orbitals.
Protein Partnering and Function
Build "partnerships" between a protein and small molecules, explore the effects of surface charge, polarity and shape on partnering, and learn the importance of a "good fit" between molecules.
Solubility
Explore molecular views of solvents and solutes to explain how substances dissolve, the differing solubilities of particular solutes in polar and nonpolar solvents, and the effects of temperature on dissolution rates and saturation.
States of Matter
How do the forces and attractions differ between the states of matter?
