Implemented in:Czech Republic, Finland and Poland

Description: The aim is that students learn to draw graphs and to interpret a velocity graph. The lesson starts with a theme presentation in the form of a video and a discussion. After that the students have to carry out an experiment using different vinegar concentrations and the same mass of bicarbonate and record the mass evolution during reaction using their cell phone. The videos are used to up draw a table indicating concentration versus time. The same procedure can be repeated using another reagent concentration. During this GP students learn to be observant, to do hands-on work and solve problems, to interpret graphs and their results, and to use computers and mathematical concepts.
