Science
Matter, energy, life, and how experiments work.
STEM Lab Edition
Learn a little of everything
Science, technology, engineering, math, and odd ideas.
The broad, experimental edition — curiosity first, subjects second.
Technology
Chips, code, and the tools we build with.
Engineering
Designing, testing, and making things that hold.
Mathematics
Patterns, proofs, probability, and useful numbers.
- 1Observe — Write down exactly what you see.
- 2Model it — Use math or a sketch to predict what's next.
- 3Test and revise — Wrong predictions teach the most.
- Variable
- A value that can change in a test.
- Prototype
- A rough version built to learn from.
- Probability
- How likely an outcome is, 0 to 1.
