1.Michael buys severalbags of balloons. On the package, it says
that each bag has 100 balloons. He opens the bags and only one
of them has 100 balloons inside, the other bags either have too
many or few. How would you describe the bag of balloon with
100 balloons inside?
2.Mica’s scale measures the mass of objects as consistently 2kg
less than their actual mass. How would you describe the scale?
3.The bowman consistently hits around the target but never hits
the bulls-eyes.
4.An archer hits the same spot on the target three times in a row.
5.An archer hits the bulls-eye.
6-10 Give Examples of tools used for measurement. (at least 5)
