ORIGIN OF OUR PROJECT

One of the authors (Martin Popik) had successfully presented project called "Chosen Features of Liquids". He had an opportunity to work with IP - Coach system, which gave him some practical and theoretical knowledge in the field of fluids and conductivity. This system is preferred in current Slovak schools and universities and it is not quite up to the current standards in technology, but it still has a good didactic value. Our project was inspired by this system. We decided to create new device able to measure and didactically show thermal conductivity of liquids. We consulted our opinions and ideas for device with many professors and teachers that were working with IP-Coach system because we wanted to know their opinion and ideas what they expect from modern measuring system. We tried to find the best way how to build our device and the teachers that had an opportunity to work with our system were agreeably surprised. The aims in this project were:

• To search for new ways to demonstrate selected features of liquids

• To incorporate modern technologies in the experiment and analysis

• Perfect our knowledge in thermal conductivity of liquids from other sources and presented projects

• To get precise data from experiments using computer processing of data

• To create new device
