Physical properties (how it feels, looks, or bends):
It is yellow and hard. It feels smooth on my fingers.
It does not bend unless it breaks.
Grading Rubric Quick Guide:
- Matching (Part 1): Give 1 pt per correct pair. Look out for students confusing 'air' as a liquid due to 'balloon'.
- Fill In (Part 3): Spelling does not need to be perfect if the intended word is clear. Each is worth 1 pt.
- Lab Report (Part 4): Item drawn must match the identified state and listed properties (e.g. if drawing water, state must be liquid, and description should mention color/flowing).
