Students investigate the paper-making process by trying it themselves. Students are thrilled to find that they can make paper and that their product is practical, as well as beautiful. You can also watch these videos of the paper-making process used in this activity: How to Make Paper (5:55) and How to Make Home Made Paper (10:41).

Preparation: 30 minutes plus time to gather materials
Activity: two 50-minute periods
- Scrap paper torn into 1” x 1” (2.5 cm x 2.5 cm) pieces (paper towels, construction paper, and toilet paper work well)
- A large bowl
- Wooden frame 5” x 7” (13 cm x 18 cm) or 8” x 10” (20 cm x 25 cm)
- Nylon or wire screen
- Plastic basin at least 2.5 gallons (9.5 liters) in capacity, that is larger than the frame
- Cloth dishtowels (felt, blotting paper, or newspaper may substituted)
- Colored paper
- Pieces of colored thread, or dried flowers (optional)
Paper is a simple material. It is essentially a mat held together by a fiber’s roughness, and can be made from almost any fibrous material such as cotton, hemp, flax, wood or recycled paper. And yet, this simple product has a tremendous effect on our lives. Imagine how different your day would be without paper!
We use paper for countless things in our everyday lives, including newsprint, magazines, schoolbooks, photocopies, computer printers, envelopes, stamps, tissue and sanitary products, bags, boxes, containers, food packaging, gift wrap, wallpaper, disposable dishes, lampshades, and as an art medium. Industrial uses include gaskets, speaker cones, liquid and gas filters, insulation, and friction devices.
The process for making paper was invented in China in the second century A.D., and all paper was made one sheet at a time until 1798. With the Industrial Revolution and the papermaking machine, papermaking became a major industry that provides countless products, from books and newspapers to packaging and note pads. Some modern machines can make a sheet of paper 26 feet (8.8 m) wide and nearly 40 miles (64 km) long in just one hour! While the technology has changed dramatically over the centuries, the basic steps are simple enough for your students to do in class.
The process begins when trees, grown especially for papermaking, are harvested and transported to a paper mill. At the mill, large machines strip away bark and shred the logs into millions of chips the size of breakfast cereal. The wood chips travel on conveyors to gigantic “pulp cookers,” where chemicals and steam are added. The mixture is heated and pressurized, breaking the chips into smaller and smaller pieces and finally forming a dilute water suspension of wood fibers called pulp. The pulp then passes through cleaners and screens and sometimes goes through a bleaching process that will give it the whiteness needed for the grade of paper being manufactured. Other chemicals such as dyes, pigments, sizings, or resins are sometimes added to provide the paper or paperboard (thick paper for boxes) with the appropriate finish.
The pulp is then pumped through pipes to a paper machine where it is sprayed onto a wide, moving wire screen. After the water in the pulp drains through the holes, a damp mat of wood fibers remains; this is the paper. It is picked up from the end of the moving belt and dried over steam-heated rollers.
Most paper comes from trees, a renewable resource. Most of the trees used for paper are managed for that purpose. In commercial papermaking, more than half of the fiber comes from lumber mill residues and from paper that has been collected for recycling.
Paper is easily recycled, which helps reduce waste. However, no matter how much paper we recycle, new trees still will be needed for paper products, because paper cannot be recycled indefinitely. Each time paper goes through the manufacturing process, the fibers deteriorate. After repeated recycling, the fiber is no longer suitable for papermaking.
Producing recycled paper requires about 40% less energy than producing non-recycled paper. And making recycled paper produces 70% less water pollution and much less air pollutants, such as greenhouse gasses, particulates, and other hazardous pollutants.
- Introduce the activity by asking students what they think paper is made of and how it is made.
- Fill the blender halfway with warm water, then add a handful of the soaked paper. Blend at medium speed until you no longer see pieces of paper, and the pulp has a soupy consistency. You can blend in a piece of construction paper for color; or stir in short pieces of thread, dried flowers, or herbs for texture.
- Pour the mixture into the large basin and then fill the basin with warm water, mixing thoroughly until the ingredients are evenly dispersed. Adding a few ounces of liquid starch will help make the paper firm.
- Slide the deckle into the basin. Put some pulp onto the screen and, still holding the deckle underwater, gently move it back and forth to get an even layer of fibers on the screen.
- Lift the deckle out of the mixture, keeping it flat. Allow it to drip until most of the water has drained off. You should have a uniform layer of pulp mixture on the deckle. Press the pulp gently with your hand to squeeze out excess moisture (rubber gloves will help). Soak up any excess water from the bottom of the screen with a sponge.
- Place newspaper on a flat surface and turn the screen paper-side-down on the cloth. Lift the screen gently, leaving the paper. Gently tap the screen to help release the paper.
- Let it dry naturally for several hours or overnight. Gently peel off the paper when it is dry.
- When you’re finished making paper, collect the leftover pulp in a strainer and recycle it, or freeze it in a plastic bag for future use. Don’t pour the pulp down the drain!
- Discuss these questions:
- What materials did we use in making paper?
- What forms of energy did you need to make the paper? (electricity and students’ own energy)
- What types of wastes resulted from making paper? (dirty water, leftover pulp)
- What did we do with the waste products?
- What were some problems with making paper? (cleaning up the mess)
- What would it be like in a paper mill, where tons of paper are being made a day? Why do you think recycling paper is important? What about reducing the amount of paper you use?
- How is the new paper different from the old paper that you recycled?
