6th Grade Polymer Recipe


The polymers that were made in class contained the following ingredients

White Glue (contains Polyvinyl acetate)

Powdered Laundry Soap (Sodium Laurel Phosphate, et al)

Liquid Corn Starch



Polymer I

Part 1 - Stir together 25 ml of white glue and 10 ml of water

Part 2 - Stir together 10 grams of powdered soap (Tide) and 25 ml of water

Combine both parts and stir until a solid polymer forms


Polymer II

Measure 25 ml of white glue and stir constantly while adding between 15 to 25 ml of liquid starch. Stop adding starch when a solid gel forms.


Polymer III

Try experimenting with with various combinations of the ingredients listed above and see if you can develop a polymer with improved properties.

Substitute Borax soap for the Tide cited above and see what results.


Measure the properties with the following tests:

Viscosity (Slump Test) - Make a ball of the polymer. Measure the diameter in cm's. Set the ball down on a flat surface and measure how big a pancake you get after one minute.

Stretch Test - Roll your lump of polymer between tour palms until it is approximately 1 cm in diameter. Grasp the roll between your thumb and forefingers with thumb-tips touching. Measure how far (in centimeters) the roll will stretch without breaking.

Bounce Test - Make a round ball out of your polymer compound and drop it from a height of 30 cm's and measure how far it rebounds when it hits a table top. Measure to the bottom of the ball's bounce. Repeat as often as you need to get a best reading.

Record all your test results and try another form of your homemade polymers.
