Units. Metric (SI) graduations, with dual units only where the curriculum needs them School science is taught in SI, and mixed scales confuse students.
Graduation readability. Molded or permanently printed markings that survive washing Printed markings wear off cheap plastic ware fast.
Material by age. Plastic (polypropylene) for young students; borosilicate glass for heated or chemical work This balances breakage risk against chemical and heat resistance.
Balance resolution. Pick the balance's readability to fit the experiment Pan balances teach comparison; quantitative labs need a real readable balance.
