Core Skills Analysis
Science
Camilla mixed white glue, water, and a borax solution to create slime. She observed the mixture change from a runny liquid to a stretchy solid, noting the shift in state of matter. She identified that a chemical reaction occurred as the polymer chains linked, learning how substances can combine to form new materials. She described the slime’s texture and its ability to bounce, reinforcing her scientific observation skills.
Mathematics
Camilla measured 100 ml of glue and 50 ml of water, then added a pinch of borax measured with a teaspoon. She recorded the quantities in a table and calculated the ratio of glue to water (2:1) and the proportion of borax needed for the desired consistency. She also estimated the total mass of the finished slime and practiced rounding her measurements. Through these steps she applied fractions, ratios, and unit‑conversion skills.
English
Camilla followed written step‑by‑step instructions to make slime and then wrote her own set of directions in clear, sequential language. She used linking words such as “first,” “next,” and “finally,” and added sensory adjectives to describe the slime’s feel. By reading her instructions aloud, she practiced fluency and comprehension of procedural text. She concluded with a short reflective paragraph, strengthening her explanatory writing.
Design & Technology
Camilla designed a slime product by choosing colours, adding glitter, and testing different consistencies to match her preferences. She evaluated the slime’s stretchiness, durability, and ease of handling, recording her findings in a simple pros‑and‑cons chart. She considered safety by wearing gloves and using non‑toxic ingredients, demonstrating responsible design. This experience introduced her to the design cycle of planning, making, and evaluating a product.
Tips
1. Let Camilla experiment with alternative polymers such as cornstarch (to make Oobleck) or gelatin to compare textures and discuss non‑Newtonian fluids. 2. Have her create a detailed lab‑journal entry with photos, measurement tables, and hypothesis‑result reflections to deepen scientific writing. 3. Turn the activity into a mini‑business by designing a “slime label” that includes price, ingredients, and safety warnings, integrating maths, English and design skills. 4. Conduct a simple investigation of how temperature affects slime elasticity by chilling or warming samples and charting the results.
