  • Agarose Gel Electrophoresis: Interactive simulation of DNA separation by size using agarose gel electrophoresis.
  • Cell Cycle and Cell Division: Interactive simulation of the cell cycle and mitosis.
  • Pollen Tube Growth on Stigma: Dissect the stigma from a petunia flower, soften and stain it with cotton blue, mount it, and watch pollen tubes growing under the microscope.
  • Column Chromatography: Pack an alumina column, load a leaf pigment extract, and separate carotene from the chlorophylls with a solvent gradient.
  • Kjeldahl's Method for Nitrogen Estimation: Digest an organic compound in hot sulfuric acid, distil the ammonia into standard acid, back-titrate the excess, and calculate the percentage of nitrogen.
  • Millikan's Oil Drop: Catch a charged oil drop, weigh it by timing its fall, and find the charge of the electron as the smallest step every droplet is a multiple of.
  • Paper Chromatography: Separate pigments from spinach leaves and flowers and determine their Rf values.
  • Rutherford's α-Particle Scattering: Fire α-particles at a thin gold foil, count where they scatter, and discover the tiny dense nucleus at the centre of the atom.
  • The Daniell Cell: Run a real galvanic cell: close the switch, watch zinc dissolve and copper plate out, and find out what happens when the salt bridge is taken away.
  • Thin Layer Chromatography: Separate a mixture of amino acids on a silica plate, develop it with ninhydrin, and identify the unknowns from their Rf values.
  • Thomson's Cathode Ray Tube Experiment: Deflect a cathode ray with electric and magnetic fields, balance the two forces, and measure the charge-to-mass ratio of the electron.
  • Photoelectric Effect: Explore how light frequency, intensity, and voltage affect electron emission from metal surfaces.
