I teach physics, and I created this quick lesson using PocketLab. I got the idea from a video they had on YouTube: https://www.youtube.com/watch?v=JlBwYWDcZSI
I used this lesson as Bell Work during a unit on Energy. The lesson is about the force of gravity acting on the accelerometer and how you can observe the Acceleration graph change as the PocketLab changes orientation. It wasn't directly related to Energy, but we were looking at GPE that day, so I thought it was a good way to get kids thinking about gravity.
The final question asks students to answer in Claim-Evidence-Reasoning format. If you aren't familiar, it's a way for students to write conclusions/explanations. You can read more about it from this article on Edutopia: http://www.edutopia.org/blog/s...soning-eric-brunsell
This was a very helpful lesson because when using the Acceleration graph previously, students were confused as to why all three axes weren't at 0g when the PocketLab was at rest. This activity helped illustrate to them that the non-0g reading is caused by the force of gravity pulling on the accelerometer and that changing the orientation with respect to Earth's gravity field will result in approximately either 1g, 0g, or -1g readings along different axes. This also lead to a cool discussion about accelerometers in cell phones and how they know to change the orientation of your screen depending on how you're holding it.
