In the 3º term, 1ºD began designing a water rocket in groups of 3. There were 10 groups. The rocket was made with recycled materials: four plastic bottles and some newspapers. It had to have four ailerons.
They cut foam board with the form that the teacher gave them, then they cut the bottles and joined them and they painted them.
After the paint was dry, they sticked the ailerons. Finally, when the rockets were finished, they launched them to the sky. Some of them flew but others not.
Here are some fotos and videos of how they worked:
