The block has a grid where six different coloured pins can be placed as shown in the diagram. See addendum Question 2.2 This is the student’s method. • place one pin into the lines of each column and row so that each pin is a different distance from the front of the grid• ask a volunteer to close one eye• hold the grid in front of the volunteer so they can see the coloured pins but not the grid• ask the volunteer to call out the colour of the pins in order of distance, from nearest to furthest• record the number of pins that the volunteer identifies correctly • repeat eight more times, each time moving the pins to different positions in the grid The student does the experiment again with both eyes open.
