Science and primary teaching are, sadly, circles that rarely intersect. When mine were in primary one of the teachers contacted me for help: she'd put a few of her yr 6's in for the higher SAT in science, but, she said, "I don't understand the answers in the mark scheme, and neither does any other member of staff, so I don't know if they've got the answers right or not".
My interesting spelling error today was "iminumu" which I achieved when trying to type "minimum".
That is interesting. All letters up and down from each other with just two fingers of the same hand. My typing mistakes normally happen with letters from both hands and I get all the correct letters but they're in the wrong order. Often completely scrambled like an anagram.
