Alexander Answers Questions About His Simple Machine Project with AudioBoo

In March and April this year Alexander worked on a simple machine project for his 8th grade science class. His design process and the results of his project are documented in the posts, “Draft Design for a Complex Machine to Generate Electricity from Water Power” (26 March 2012) and “Good Things Can Come From Science and Engineering Projects in School” (30 April 2012). After sharing those results, I received some feedback via Twitter from Arizona 5th grade teacher Michael Buist. His students looked at the design photos and videos Alexander created, and wrote an extensive series of questions for him about his project, design process, and lessons learned.

This evening Alexander answered a few of the questions using AudioBoo on an iPad. He actually asked to answer with just audio, since he didn’t need to show anything on his actual project in a video to answer the questions. Here are the student questions written by some of Mr. Buist’s students and Alexander’s recorded answers. There were many more questions shared by students, but these were the ones Alexander was able to answer tonight. Thanks Mr. Buist and students for your interest in Alexander’s project and his learning journey as a designer and engineer! I hope the information we share is helpful to you in your own engineering design projects.

Questions from Jonah C:

Did you have fun doing this project, or did you just do this for a good grade? If you did have fun with this project, what were the most fun parts of the project that you had?

If you did not like this and just did this project for a grade, then what did you not like about the project? What kind of help did your dad give you, or did you just do the project by yourself?

Question from Braxton B:

One of the questions that I have about the second design is why even use the pulley when you still have to use your hand to help it along I hope you can answer my questions a thank you for listening.
