Tennis Ball Team Building Game
For the tennis ball challenge, we split the class in half and both teams had to find the fastest way to pass the tennis ball to everyone. At first we just put our hands close to each other so that the ball could touch everyone, and that was pretty fast. Then, we had to have the ball in the air from person to person and not just sliding through our hands. We came up with a step slide design, where we put our hands at an angle and had one slightly in front and lower than the other. This was fast too. Finally, the final constraint was that we had to be at least within arms length of each other. In this case, we just formed a circle and tried to pass it to each other as fast as we could. Looking back at the first 2 parts I think that they couldn't have been done any better, but I have a different idea for the last one. We could have thrown the tennis ball across and have everyone slightly touch it, which I believe would be considerably faster than anything else.
Concerning the survival challenge, I thought it was quite interesting because I had to think about the uses for each of the items we had for use. I think that everyone had water ranked 1st, followed by rations. This is kind of the logical route for everyone because the first thing you think you'd need when you're stranded is food and water. With the coast guard, it was more on getting rescued than on staying alive. Therefore, they had the shaving mirror ranked 1st. My ideas and my group's ideas were pretty much the same because our idea was of staying alive rather than being rescued right away. An idea to make this activity more interesting would be using the same list but having you choose only 3-5 items that you would take. This would really change the priorities from getting rescued or staying alive to finding the few things that you could take that would be the most efficient.
