Learn how electromagnetic fields guide the motion of charged particles and why electric and magnetic forces shape their paths in predictable ways.

Learn why electric charges create fields around them and how electric fields explain forces without direct contact.

Learn how atomic trends help predict the types of bonds elements form and why electronegativity and ionization patterns shape bonding behavior.

Learn why waves spread out (diffract) when passing through openings and how wavefront interactions create curved, expanding patterns.

Learn what the photoelectric effect reveals about the nature of light and why it shows that light behaves as quantized photons.

Learn why the absorption and re-emission of infrared radiation matter and how they create warming effects that shape Earth’s climate system.

Learn why atomic radius decreases across a period and how nuclear charge and electron shielding explain periodic size trends.

Learn what determines nuclear stability and how the balance of forces, neutrons and binding energy shapes atomic structure.

Learn how transcription factors regulate gene expression by binding DNA, activating or repressing transcription, and shaping cell identity.

Learn why double and triple bonds affect molecular geometry differently from single bonds and how electron density influences bond angles.

Learn how gas laws emerge from the collective behavior of countless microscopic particles and why pressure, volume, and temperature relationships arise naturally.

Learn how particle motion explains conduction, convection, and radiation, and why heat naturally transfers through microscopic interactions.

Learn why strong acids ionize completely while weak acids only partially ionize, and how bond strength and stability determine acid behavior.

Learn why particles behave like both waves and particles and how quantum mechanics unifies these seemingly contradictory behaviors.

Learn why dynamic equilibrium involves forward and reverse reactions occurring simultaneously and how balance is maintained at the molecular level.

Learn why splitting a heavy nucleus releases so much energy and how nuclear binding energy explains the power of fission.

Learn how wave properties emerge from oscillatory sources and why frequency, wavelength, and amplitude arise naturally from repeating motions.

Learn what Lenz’s law reveals about nature’s resistance to change and how induced currents always oppose variations in magnetic flux.
