DS1's year 5 class were split into four groups. Two of the groups were asked to design and build a machine, using levers etc, that could drop an egg from 6 feet without breaking it.
They were told that the best one would enter and inter-schools science competition.
Both groups demonstrated their machines to the whole class and DS1's group machine managed to drop the egg without breaking it. The other machine broke the egg.
The teacher then said that 'as everyone had tried very hard' she would put it to a class vote to decide which machine would enter the competition.
The group with the broken egg had three very popular pupils in it and, according to DS1, the class voted for their machine because of this.
He's not losing sleep over this but he's confused as to why the best (ie. the machine which did what was asked) wasn't just put forward for the competition.
BTW. The competition was at the end of last week and, yes, the machine broke the egg, again.
