25th February, 2021 Geography
I Introduction
- short film about Lake Balaton and its geographical features
- measuring the temperature of air and water on the shore
- pH measurement – short movie + summary of data
- the wind – measurements on the shore of Lake Balaton
- illustration – the formation of the offshorewind
- Why is the wind important for sailers? - short film about how Róza sails
- the Lake Hévíz and Egerszalók video – special thermal waters of Hungary
- Karstification - How does it happen? – Luca` s explanation
II Experiments in the lab
- video about the experiment on the sand table
- water permeability of soils – live experiment in the lab
III Summary test
watching the video
2nd March, 2021 Chemistry
I Introdution
- presentation of the geochemistry of Lake Balaton: the main rocks, sediments of the catchment basin which influence the content of the sediment and the water of the Lake.
II Expriments
- pH value: 3 samples in test tubes and reagent added; the colour change; the pH value of the waters can be observe
- the total hardness of water: calcium- and magnesium-ions from the water samples are measured by adding reagent and watching the change in colour
- total salt content: samples are put into beakers and heated until all the water has evaporised, the percipation can be seen
- sugar content of soft drinks: Fehling reaction is used to detect the sugar content of some soft drinks
If the sample (soft drink) contains sugar (glucose and/or fructose) the sample and the reagent changes from blue to green and red when heated. The speed of the reaction depends on the concentration of the sugar.
III Summary
- the results of the experiments shown
- dicussion on the results with the help of questions in small groups

VitalCapacity– Comparison of lung capacities
| According our video recording you can blow air through a PVC-tube (6mm diameter, about 60-80 cm length). The competition is going to be online, and let’s suppose, the Internet will not produce 3-4 – second delays!
| Ions - as the base of eletric current in fluids |
