Science
Jack mixed 1/2 cup of glue, 2 cups of shaving cream, 3 tablespoons of contact solution, and food colouring to create a basic slime. He then added a teaspoon of borax and observed the slime become rough, crunchy, and noticeably drier. After a second teaspoon of borax, Jack recorded that the slime separated into chunks, losing its smooth texture while remaining soft. Through this experiment Jack learned how a chemical additive can change the physical properties of a polymer by creating cross‑links.
Mathematics
Jack measured ingredients using fractional units (half‑cup, teaspoons, tablespoons) and recorded each amount on his worksheet. He compared the volume of glue to the volume of shaving cream and noted the ratio of liquid to foamy components. By adding a precise teaspoon of borax twice, Jack practiced repeated addition and unit conversion, reinforcing his understanding of measurement accuracy and proportional reasoning.
English (Language Arts)
Jack wrote detailed observations after each addition of borax, describing texture, dryness, and visual changes in complete sentences. He used scientific vocabulary such as "texture," "dry," and "cross‑linking" to articulate his findings. This practice helped him develop clear scientific communication skills and structured note‑taking aligned with the scientific method.
Tips
1. Have Jack formulate a hypothesis before each new ingredient is added and test it with a controlled repeat of the experiment. 2. Extend the investigation by mixing borax into the slime at the start to compare results with the step‑wise addition. 3. Connect the slime chemistry to real‑world applications, such as how polymer science is used in clothing or medical devices, through a hands‑on model or video. 4. Turn the observations into a visual timeline poster that tracks texture changes, encouraging both scientific reasoning and artistic expression.
