Throw each airplane multiple times to get a variety of measurements that we can plot on a graph.įrom our experiment, it seems like all of the paper airplanes flew roughly the same distance, regardless of paper weight. Try to be consistent with the force and angle of each throw. Pick a nice spot without much wind, preferably indoors, and throw each airplane. For example, my hypothesis might be that a heavy dart will fly further than a light dart, or that a light glider will stay aloft longer than a heavy glider.įinally, it's time to throw some paper airplanes. A hypothesis is a guess about what we think will happen. Make sure that each airplane is the same size and is folded the same way. Pick you favorite design and fold it using each different thickness of paper that you have. If you are going for time aloft, we recommend the Stealth Glider because it glides consistently without much adjustment. Are you trying to throw the airplane the furthest, have it stay aloft the longest, or some other criteria? If you are going for distance, we recommend the Basic Dart because it is quick and easy to fold. Now that you have paper with a variety of different weights, we are ready to experiment and determine which is best. Paper sold in office supply stores often has both measurements listed on the package to help us out. Luckily, the metric system is here to save the day, with a system called "grammage". As with most imperial measurement systems, it's complicated! But there are other base sizes (Offset, Cover, Bristol, Index, Text, etc) so it's difficult to compare paper using this measurement system unless you know how each piece of paper is manufactured. The 17 x 22 inch size we mention is called "Bond" and you may see "bond weight" marked on the package. Unfortunately, different types of paper have different base sizes. So.Ī ream of "20 pound" paper that you buy in the store should weigh about 5 pounds. The base size of regular printer paper is 17 x 22 inches which is then cut down to make 4 pieces of paper. This is because it's actually the weight of the base size of the paper during the manufacturing process before it is cut down to its final size. If you've ever picked up a ream of paper, you may notice that it doesn't weigh 20 pounds. Regular printer paper is typically labeled as "20 pounds" and is sold in a ream of 500 sheets. This is the weight of one ream of paper, in pounds. If you use Letter Paper, then your paper is measured using a system called "basis weight".
