Water & Paper Science Projects
Science projects give students the ability to recreate scientific discoveries and learn through experience how one element or object affects another. Simple science projects involve items found already at home or in the classroom. Some companies provide full science project "kits" available for purchase online, but these are not necessary to come up with water and paper science projects for kids to experiment with.

Pain Relievers
-
Pain relievers are made differently and will dissolve at various rates depending on the chemical makeup of the liquid it gets submerged in. Place three clear glasses out, each with about 3 inches of warm water. Leave the first with plain water only, put 1 tsp. of salt in the second one and 1 tsp. of sugar in the third one. Stir the second and third glasses until the salt and sugar are dissolved. Drop one tablet of your choice of pain reliever in each glass. Time how long each one takes to dissolve.
Temperature
-
Record how temperature affects the speed at which water freezes. Take a plastic container half full of cold water and one container half full of nearly boiling water and place thermometers in each one. Record the temperature and remove the thermometers. Place them both in the freezer at the same time and monitor each one every five minutes. Record which one froze fastest or if they froze at the same time.

Paper Towels
-
More than one top brand of paper towels make claims as to how well they absorb liquids compared to other brands. In this experiment, you can try four to five different brands of paper towels. Place out 1/2 cup of water or other liquid on a flat surface. Place one sheet of paper towel over the spill and record your findings. Repeat with the other brands of paper towels you chose. If you don't have contrasting surface color to verify how much water is left on the surface, consider adding a few drops of food coloring to the water to make it more identifiable.
Paper Plunge
-
Try to keep a scrunched up newspaper from getting wet even when you submerge it in water. Fill a large clear bowl with water till it is 75 percent full. Mash up a piece of newspaper and stuff it in the bottom of a smaller glass container, such as a drinking glass, so that it is wedged tightly and cannot fall out. Tip the glass upside down and push it straight down into the water in the larger clear bowl. Record what happens. Repeat the exercise while tipping the glass at a 45-degree angle and see what happens. Try to explain why the experiment was a success or why it failed.
