This scenario is about how to create a “heart” and to organize its “pulsating” in order to make an animated “Valentine’s card”. To do this we have to use some mathematical knowledge and GeoGebra functionality to: (i) get a heart-like shape, and (ii) organize the “pulsating” of the heart. The first part can be achieved by: inserting a picture; painting a heart in a free-hand style; using different mathematical figures and curves, etc. The animation part (the “pulsation”) allows students to get familiar with the notions “cycle” and “dilation”. The scenario reflects the principle of the MaSciL project of integrating Inquiry Based Learning with the world of work (in this case, the graphic design applications for decorative arts).
