# Science Learning Curriculum

A large collection of structured learning units covering the scientific method, physics, chemistry, biology, earth and space science, and supporting mathematics.  

Content is organised by domain, topic, difficulty level (1–10), and unit type (explanation, worked example, practice problem, etc.). Each row contains a self-contained pedagogical text together with key equations, prerequisites, and an explicit learning objective.

## Columns

- `id` – unique identifier  
- `domain` – broad scientific domain  
- `topic` / `subtopic` – hierarchical organisation  
- `difficulty` – integer difficulty rating  
- `unit_type` – type of learning unit  
- `title` – short descriptive title  
- `content` – main pedagogical text  
- `key_equations` – relevant equations  
- `prerequisites` – required prior knowledge  
- `learning_objective` – stated educational goal
