This is part 2 in my posts about Sphero (see part 1).
So passing out Spheros and iPads has become a load easier and there are a few things that helped.
- At the end of the session, having students un-pair the device (forget this device) before shutting down the iPad helps during the next session. This also eliminates the necessity of using a specific iPad with a specific Sphero. Un pairing happens in the bluetooth menu.
- Starting only one or two Spheros at a time makes a difference, too.
- Keeping one or two Spheros and iPads as a back up. This helps me quickly switch out any “troublesome devices.” Right now I have 8 shperos on an investigation and two back up.
During these last sessions students were working with the parameters of the “ROLL ” function in Sphero Macro Lab. Students can change three different parameters of “ROLL”: %of power, time of travel, and heading (direction in degrees.)
Students were investigating the power of Sphero. In other words, “How far will Sphero go when we manipulate the % of power and time of travel?” This is the D=RT formula. It is also the multiplication chart.
I wanted the students to find all the combinations and fill out a chart that they could use as a reference to program a Sphero to move through a maze. They need to know how far it will go when they set the parameters and they need to know what parameters to set to make the Sphero go a certain distance. My ultimate challenge is to see a Sphero programmed to go from the classroom to the school office. We are a ways off but getting closer everyday.
next up, students will be using the Heading parameter to have the Sphero trace out geometric shapes such as right isosceles triangles or hexagons. This pairs great with degrees of a circle and using protractors.
Having a great time exploring new tech in the classroom.
