Mini-Demo Plan
Name: Jesse Armstrong
The answers to the questions below should serve as your lesson plan.
Also, indicate how much time you will allocate to the different parts of your presentation.
1. What is the name of your demo?
Making Slime
2. What topic area (or unit) would this fit into?
Chemistry 20: Molecules and Compounds
3. What curriculum guide outcome(s) would this demo fit into? (provide a minimum of
one). Be sure to list the course and the outcome (including the code and written
outcome)
*There are no codes for this curriculum because it is from 1992
"Discuss the Mechanics of bonding between atoms in a molecule" (Saskatchewan
Chemistry 20 Curriculum ,p. 90).
"Examine the bonding between molecules or atoms in solid and liquid phases"
(Saskatchewan Chemistry 20 Curriculum, p.90).
4. What equipment and materials are needed for this demo?
● Elmers Glue (8 oz bottle) ● One Teaspoon Borax ●Large mixing bowl ●Plastic cup
●Wooden spoon ● Measuring cup/beaker ●Food colouring ● 1/2 cup warm water
●Paper Towel ●Ziplock bag
5. What safety precautions are there for this demo?
● Students with sensitive skin may react to the laundry detergent, Borax, if it comes in
contact with their skin
● If food colouring comes into contact with clothes, it may dye them a different colour.
6. What should the students be able to do or explain after seeing this demo?
Students should be able to understand and explain how adding Borax to the glue
creates a chain of molecules referred to as a polymer.
Sci-Guys: Polymers
-Excellent explanation on polymerization, which would be a great short clip to show in a class.

7. What are the steps in your demonstration?
1 Minute- Provide each table with the necessary equipment and directions
2 Minutes-Show the class one step at a time and have them complete it until all steps are
complete and the slime is created. Each table will be provided with the step by step

directions. When students add Borax to the glue, ask them what is happening to the
texture of the mixture.
1 Minute - Ask students how the glue and Borax mixtures came together to form slime.
Remind students of molecules and the binding of molecules to develop a polymer, or
chain of molecules.
1 Minute-Provide students Ziplock bags if they want to keep their slime. Clean up.
Directions:
1. Empty the entire 8 Ounce bottle of glue into the mixing bowl.
2. Fill the empty bottle of glue with warm water, replace the cap, and shake for 10-20 seconds.
Pour the glue-water mixture into the bowl and mix well.
3. Add one or two drops of food colouring to the mixing bowl and combine.
4. Measure 1/2 cup of warm water into a measuring cup or beaker and add a teaspoon of Borax
powder to the water. Stir the solution.
5. While stirring the glue in the mixing bowl, slowly add some of the water spoon and Borax
mixture into the bowl. Use your hands to continue mixing and keep adding the Borax solution.
6. Have fun with your slime and place it in a Ziploc bag to transport.
8. How will you bring your presentation to a close?
To bring my presentation to a close I will have students try and answer what happened
when Borax was added to the glue mixture. Through inquiry learning, I will try to have students
come up with the reason before I provide the answer. If students are stuck, I will explain
molecules and the creation of polymers.
