Step-by-Step Procedure

  1. 1

    In a mixing bowl, combine 1 cup of white school glue with 1 cup of water.

  2. 2

    Stir the mixture until fully combined.

  3. 3

    In a separate container, mix 1 teaspoon of borax powder with 1 cup of water, and stir until dissolved.

  4. 4

    Slowly add the borax solution to the glue mixture while stirring continuously.

  5. 5

    Observe the slime forming and continue to mix until desired consistency is achieved.

  6. 6

    Add food coloring to customize your slime, mixing until even.

  7. 7

    Knead the slime with your hands to improve texture.

  8. 8

    Store the slime in an airtight container.

  9. 9

    Discuss the polymer chemistry involved in slime formation.

  10. 10

    Present your slime experiment findings.

Expected Results

The combination of glue and borax will create a stretchy, moldable slime due to the formation of a polymer network. This demonstrates the properties of polymers and cross-linking.

Variables

Independent Variable

Concentration of borax solution

Dependent Variable

Texture and elasticity of the slime

Controlled Variables

Amount of glue, Amount of water, Temperature during mixing

Safety Notes

Wash hands after handling materials. Avoid ingesting any ingredients used in the experiment.

Presentation Tips

  • Bring your slime to demonstrate during the presentation.

  • Explain the science behind polymers in simple terms.

  • Engage the audience with slime-making demonstrations.

  • Discuss potential applications of polymers in everyday life.

  • Practice your presentation to ensure smooth delivery.

Frequently Asked Questions

What causes slime to form?

Slime forms when glue (polyvinyl acetate) reacts with borax, creating a cross-linked polymer.

Is slime safe to play with?

Yes, slime made from glue and borax is safe for play, but it's important to avoid ingestion.

Can I make slime without borax?

Yes, there are alternative recipes that use cornstarch or contact lens solution.
