This week is all about Spinning! Interita! Friction! Momentum!
What a better test for all those concepts than to take our Spheros on their first outing to the beach. It was a very windy day at Lake Michigan, that is for sure! We got Nubby covers for them so they could handle the terrain, but they didn’t work at all…. Sphero just spun inside the cover – a good demonstration of a very low coefficiet of friction – not what we were looking for, so it never really got any traction at all on the sand and therefore, never moved. So we came up with a different version of the cover – we call it the PLASTIC WRAP PROTECTOR!!!! Made with two simple layers of plastic wrap. Amazingly, the PLASTIC WRAP PROTECTOR worked better than the $15 nubby cover.
With tech in hand we began our grand journey up and down mini sand dunes, across the parking lot, jumping through mountains of sand, and (here’s the scary/ unnerving part) through the WATER!!! AAAAHH!!! Nuts, I know but as students, we seemed to handle it fairly well… seeing it going into the base of the waves, it just tempted us to jump in after it. The water seemed like it was in the mid 40’s, so a quick rescue would have to be in order. Technology in WATER. It was WILD! Happily, we never had to rescue it :0)
After the lovley morning at the beach with our both our Sphero friends, practicing our spelling words in the sand and getting plenty of exercise, we are looking forward to a morning when the wind is still, the lake has no waves and we can take them back to the beach and see them swim!
