What Nova teaches
Five thinking tools for life.
Data literacy
Read a chart properly — and notice when one is misleading you.
Building a case
Structure an argument, cite a source, anticipate the counter.
Deep dives
Long-form topics: climate, elections, money, the internet.
Debate
Argue a side you disagree with — properly, and in good faith.
The lesson path
