Smartphones as didactic tools
How to link chemistry and earth science in high schools? Chemistry is considered difficult by teenagers because of its language and themes. Geosciences are often left in the corners and in particolar the teaching/leaening of minerals and rocks is particulary boring. It is important to find new ways to ensure taht students fall in love with these disciplines. In our project we adpted an inquried based methodology: students pose and answer questions in different steps. Starting from students' answers many activities were carried out in groups to discover the proprieties of the elements contaned in a mobile phone.
