Hi, this is Mika Tanaka from Japan.
I am teaching junior high school students.
I have several questions for developing a lesson plan about measuring the speed of a falling object with Sphero BOLT.
The final goal of my lesson is that my student will be able to calculate the speed of a falling object from 50 meters.
In my lesson plan, my students will drop Sphero from each distances, 0.5, 1, 1.5 meters.
Then they will get the sensor data and CVS to find the speed numerically.
After that, they will create a graph about the relationship of the distance and the speed. ( the graph supposes to be in direct proportion between these two variables.)
When the graph is completed, they will try to calculate the speed of falling a abject from 50 meters.
I tried this procedures by myself, but I found several problems.
When I provided the CVS to check the result numerically, it showed not really precise results.
I think it is because Sphero BOLT measeures the speed with only X axis and Y axis.
Is there any great way to make my lesson plan possible?
