problem
if someone shot a gun, how can you tell if it was from up close or far away? -
Period: to
marner
-
hypothesis
i believe that when you shoot from far away, any spots will be small but the splatters will be in a larger diameter. -
materials
pen
notebook
drinking straws
large butcher paper
tape
ruler or yardstick
lined paper
food coloring -
procedure
fill a cup with water and mix in food coloring. then tear a small piece of paper and put it in a straw. dip the straw in food coloring and spit the paper on towards the larger butcher paper. repeat the steps but use a ruler so you can know where to shoot from 1, 6, and 12 inches. when the paper is dry measure the diameter of the splatters. then look to see how big the spots in the splatter are. decribe the sizes in your notebook -
conclusion
the paperwad that had been shot from 12 inches away ( i call it the atomic bomb of Aruba) had the biggest splatter but the smallest spots. -
analysis
when you are far away, the splatters will be bigger because the spots have more time to expand and widen the diameter of the splatter.
