To make paper airplanes for a science project, paper of varying thicknesses should be used to determine which is the most effective. These might include copy paper, construction paper or other heavier paper, as well as paper clips for experimenting with weights. The basic model is made by folding copy paper. Variations on the design are then created and the flight results recorded so that they can be compared with the original.
Step 1: Fold the sheet of paper down the middle
That is, fold the sheet of paper lengthwise along the 11 inch dimension.
Step 2: Fold the upper two corners
Fold the upper two corners at a 45 degree angle to form the nose of the airplane, ensuring they are lined up and do not cross the middle fold.
Step 3: Fold the sides
Fold each side down, using the middle crease as a guide. These should also be even.
Step 4: Fold the wings
Finally, fold the wings down to meet the base of the original fold from Step 1.
Step 5: Experiment with stability
When varying the design, folding the wings up at the edges to create winglets can help with stability. Likewise, thicker paper will ensure greater stability of the form. Paper clips may be used as weights, so experiment with them to create a center of gravity ahead of the airplane's neutral point.Learn More
To make glacier for a science project, empty the contents of an 8-ounce bottle of glue into a bowl. Refill the glue container with warm water, shake, then pour the water into the bowl. Add 2 drops of blue food coloring. In a plastic cup with 1/2 cup warm water, dissolve 1 teaspoon of borax powder. Slowly add this solution to the glue mixture while stirring to form glue slime.Full Answer >

Paper is used to make books, magazines and newspapers as well as paper money and photographic paper. It's used to make writing paper, toys, boxes, wrapping paper, glassine, paper napkins, toilet paper, paper towels, facial tissue and paper plates. It's also used for wax paper, parchment paper, filter paper, insulation, roofing felt, wallboard and gypsum board. Some further uses are envelopes, wrappers and butcher paper.Full Answer >
