Piece of paper activity

You will need: an ordinary piece of paper

This activity starts with a couple of ideas of things to do with a piece of paper and then it will be up to you to come up with something new to do with the paper.

1. Try rolling up the piece of paper to make a cylinder shape. Stand the cylinder on one end. Is it strong enough to support something? Which way did you roll the piece of paper? Was it a long cylinder or a short cylinder? Try rolling it the other way. Is it stronger now?
2. Hold the piece of paper high above the ground and let if fall to the floor. Does the paper fall quickly or slowly? If you fold the paper in half, will it fall any faster?
3. Now it’s your turn. What can you think of to do with the piece of paper? Give yourself a few minutes of thinking time to hold the piece of paper and imagine something to do with the paper that you have never thought of doing before.

What’s happening?

Creativity in science often involves thinking about existing ideas and imagining something new. Taking the time to look at familiar objects in new ways can lead to exciting new thoughts, inventions, and discoveries.

Let’s explore the nature of the Universe with five fun and fascinating fast facts about the four fundamental forces, an interview with Professor Lisa Harvey-Smith, an astrophysicist who knows a lot about the Universe, and a surprising paper folding activity for you to try yourself at home.

Paper folding activity

How many times do you think you can fold a piece of paper in half?

You will need: a long piece of toilet paper.

1. Lay the toilet paper out on the floor and fold it in half lengthways. That’s one fold.
2. Keep folding the toilet paper in half over and over again and remember to count each fold. After 4 or 5 folds, the bundle of paper will be getting fairly thick. Can you keep folding?
3. Keep folding until you cannot fold the paper in half anymore.

What’s happening?

The toilet paper is pretty thin, but every time you fold it in half, the thickness of the bundle of paper doubles. After one fold, it is twice as thick as the original toilet paper. After the second fold, the bundle is 4 times as thick. After the third fold, the bundle is 8 times as thick, then 16 times, and then 32 times, and after the sixth fold, the bundle is 64 times thicker than a single sheet of toilet paper.

The current world record for folding a piece of paper is 12 times and the record was set in 2002 by Britney Gallivan, a high school student in the United States. Britney used mathematical equations to work out the size and thickness of the paper she needed to achieve the record, and the tissue paper she used was over one kilometre long! After the 12th fold, the bundle of paper was 4,096 times as thick as a single layer of tissue paper.

Bioplastic activity instructions

Ingredients: 1 tablespoon of cornflour, 4 tablespoons of water, 1 teaspoon of vinegar, ½ teaspoon of glycerine, and a few drops of food colouring.

Kitchen equipment: a small saucepan, stove or hotplate, metal spoon for stirring, and a baking tray on a heat-proof surface.

1. Add all of the ingredients to the small saucepan and stir with the metal spoon until everything is well mixed.

NOTE: An adult must assist with the next steps that involve heating the mixture on a stove or hotplate.

1. Stir the mixture over a medium heat and keep stirring with the metal spoon until the mixture starts to boil.
2. Reduce the heat and keep heating and stirring for 2 or 3 minutes.
3. Pour the hot mixture onto the baking tray and spread it out to make a thin sheet.
4. Leave the sheet of bioplastic film to cool and dry for 1-2 days. The finished bioplastic film should be see-through and flexible.

This recipe can also be used to make moulded bioplastic shapes by pouring the hot mixture into silicone moulds (e.g. silicone ice-cube trays). The bioplastic in this activity is ‘compostable’, which means it will break down in a compost heap or if it is buried in the ground.

Corn flour contains starch which is made up of ‘amylose’ and ‘amylopectin’ molecules which are both made up of glucose molecules. Heating corn flour with water causes some of the starch to form long chains. Vinegar affects the formation of the long chains. The glycerine acts as a ‘plasticiser’ which is a chemical that can change the softness and pliability of a plastic. Changing the amount of glycerine in the recipe will change the properties of the bioplastic film.
