To do this, we built a cannon made of tiner cans and prepared a serie of activities that have been subdivided into three phases: construction, competition and activities with the use of the software GeoGebra. The work done with students in these aroused a greater interest in the matter and was extremely valuable because students did not forget the acquired learning. / Neste trabalho apresentamos o desenvolvimento e a implementação de uma sequência didática a fim de motivar e ensinar os alunos do Ensino Médio o tema funções quadráticas. Para isto, construímos um canhão feito de latas de tiner e preparamos uma série de atividades que foram subdivididas em 3 fases: a construção, a competição e atividades com o uso do software GeoGebra. O trabalho realizado com os alunos despertou nestes um maior interesse pela matéria e foi de extrema valia, pois os alunos não se esqueceram do aprendizado adquirido.
