Observing
The picture on the right has five differences to that on
the left. Can you spot all five?
Get four pairs of tights, put weights down one leg
and measure how much they stretch.
Results:
(5)
2.
What happened: All the tights stretched different amounts. The thin
blue stripey tights stretched the most. They stretched
14cm more than the shortest tights. The thickest tights
didn’t stretch much. They stretched 12cm less than the
yellow tights. There were two pairs of blue tights and
they stretched more than the pale coloured tights.
What we learned: If you want tights to stretch a lot you should buy
pale colours.
