F2k Student Laboratory

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 5th to 9th graders.

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 research centre visits 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 all school groups from grades 5-12 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.

Physics experiments for 5th to 9th graders are now available as well. These are "Infrared Radiation and Climate Change" (max. 25 students, suitable for younger students, 45-60 minutes) and "Everyday Physics: Electromagnetism and Sound" (max. 20 students, suitable for 7th to 9th graders, 75 minutes). More English-language information on these will be published later in 2019; in the meantime, ask for more info!

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.

Double Slit Experiment With Single Photons. 1 setup, 1-5 students. No written instrution sheet exists yet, but the setup is operational. Ask for more info. Suitable for visiting groups (combined with some other experiments), and works well for project working as well. Eg. ask students to book a time at the lab and take 2 hours to learn how to use the apparatus and take measurements, then turn in a report to you.

 

 

Experiments for grades 5-9

 

Thermal Radiation & Climate Change

  • 6 setups, 1-4 students each. Experimenting with thermal cameras with special focus on materials' transparency to infrared radiation. Balloons are filled with CO2 to show that CO2 is a greenhouse gas.

 

Sound & Electromagnetism

  • Currently not translated into English. Available without worksheet, ask for more info.
