Materials

The materials required for this science fair project:
- 1 ramp elevated at 45 degrees
- 2 pieces of cotton cloth
- 2 pieces of silk cloth
- 2 pieces of linen cloth
- 2 pieces of wool cloth
- 2 pieces of polyester cloth
- 2 pieces of nylon cloth
- 1 roll of Scotch tape
- 1 pair of scissors
- 1 ruler
- tap water
- 1 measuring cylinder
- 1 plastic bottle with holes on the cover (a self-deviced water sprinkler)
- 1 digital weighing scale

Procedure

1. For this science fair project, the independent variable is the use of Scotch Guard and the type of fabric tested - cotton, silk, linen, wool, polyester and nylon . The dependent variable is the amount of water absorbed by the fabric. This is determined by measuring the weight of the fabric before and after wetting the fabric. The constants (control variables) are the size of the fabric, the elevation of the ramp and the amount of water dispensed.

2.   The twelve  pieces of cloth are cut into the same size and their weight is checked on the digital weighing scale.  Two pieces of fabric of the same type should have the same weight. If not, trim the edges of the heavier piece very slightly and re-weigh to see if they are now of the same weight. Repeat the process until they are. The measured weight is recorded in the table given below.

3.  One piece of cloth from each type of fabric is treated with  Scotch Guard.

4. The first piece of  fabric to be tested is spread on the ramp. The sides of the fabric are taped with scotch tape to prevent  water from entering the sides. 300ml of water is measured and poured into the plastic bottle and the cover screwed on. All of the water from the bottle is then sprinkled over the cloth and it is left on the ramp for 5 minutes for the excess water to flow ff.

5. The fabric is removed from the ramp and its weight is  recorded in the table below.

6.  Procedures 4 and 5  are repeated using the fabric that was treated with  Scotch Guard.

7. Procedures 4, 5 and 6 are repeated using the remaining 5 types of fabrics and their  weights are recorded in the table given below.
