Vehicles of all varieties pass us by everyday, and we are so used to them that we don't really notice just how many there are! Find a comfy spot in your garden or front room and keep a tally of how many different vehicles drive, cycle and fly by during a set period of time. When you have gathered your results, use them to create a bar graph (you could do this on paper, or by using J2data).
If you would like some squared paper, please let me know and I will get some ready for you.
What did you notice?
Were your results surprising?
