F2k

F2k offers Physics Department and INAR study visits at the University of Helsinki. Our main focus is on modern physics experiments tailored for high school students, but we also provide hands-on experiments for junior high students.

If you wish to bring your class to visit the Physics Department for lab work or to visit one of our research labs, contact the Physics Education Coordinator! Both lab workshops and visits to authentic research centres can be arranged in English when requested.

The F2k laboratory uses experiments to illustrate the phenomena that took scientists from classical physics to contemporary physics. Important themes include the quantisation of light, matter and charge. Experiments on the elementary charge, the charge of an electron and the photoelectric effect relate to the final courses in high school, but schools often lack the necessary equipment to stage them.

The laboratory is particularly well suited to high school courses on modern physics, but other high school groups are welcome to visit. Introductions to the Department of Physics, studies in physics and physics research (e.g., a visit to a research department) can be organised for visiting groups.

New experimental setups for junior high shool students (around ages 12 to 15) will be available from January 2019.

High school experiments

 Spectral analysis. 1 setup for 1-6 students. Applicable for all age groups.

*Photoelectric effect. 2 quantitative setups for 1-4 students each, 1 qualitative setup (optional). Useful background knowledge: voltage, charged particle in electric field, frequency and intensity of light.

 Millikan Experiment. 1 setup for 1-5 students. It is recommended to use the apparatus qualitatively, observing droplets in the electric field and focusing on how the experiment is designed. Useful background knowledge: voltage, charged particle in electric field, alfa particles, extrapolation.

 *Electron charge to mass ratio. 2 setups, 1-4 students each. Classic Thomson Experiment. A visually pleasing experiment that ties in Northern Lighs, electrons, magnets, and circular motion. Useful background knowledge: voltage, charged particle in electric and magnetic field, circular motion, multivariable slopes for functions, magnetic field inside a coil.

Induction. 2 setups, 1-4 students each. Observing induction with an oscilloscope: how are the input and output signals of a two-coil setup connected? Useful background knowledge: induction, AC, magnetic flux, derivative.
