The students were very excited to have some practical sessions and to build new technologies themselves. We worked with the 35 students in Standard 7 (7th grade) and they brought the perfect balance of curiosity, enthusiasm and inquisitiveness to the sessions. The teachers themselves wanted to help us as much as possible and get a glimpse of what sorts of activities we were running.
The most successful activities were probably having the students build their own maize shellers (for removing kernels from the cob)  and demonstrating the bicycle-powered blender. They worked with sheet metal and learned basic metal-working skills. As they worked in teams through the assembly process, they were clearly feeling more and more confident about their ability to make their own technologies. The second activity with the blender was a great exercise to encourage the students to think creatively about the machines they have around them.
