* Accessibility and affordability: It's inexpensive and readily available, making it a practical adhesive for educational and creative projects where expensive, specialized glues aren't necessary.
* Ease of use: It's easy to apply, doesn't require special tools or expertise, and cleans up relatively easily (when still wet) with water. This makes it ideal for children and beginners.
* Versatility: While not the strongest adhesive, it's suitable for bonding a wide variety of materials commonly used in school projects, such as paper, cardboard, wood (thin pieces), fabric, and some plastics.
* Safety: PVA-based school glue is generally non-toxic and safe for children to use under adult supervision, although ingestion should always be avoided.
* Educational value: Using school glue in crafts and projects helps children develop fine motor skills, creativity, and problem-solving abilities. It's a fundamental tool for many hands-on learning activities.
In short, school glue's importance lies in its combination of safety, affordability, ease of use, and versatility, making it a crucial tool for education, arts and crafts, and simple household repairs. It's not the *best* adhesive for every job, but it's an excellent *everyday* adhesive for its intended purposes.
