About NexusForge
A systems-thinking playground for ages 9–14.
What it teaches
Systems thinking is the skill of seeing how the parts of something — an ecosystem, a city, an economy — connect and push on each other. NexusForge builds it through three moves: quick concept kits, a Causal-Loop Lab where you predict how a nudge ripples through a system and whether its feedback loop reinforces (builds on itself, like a spreading rumor) or balances (settles down, like a thermostat), and a Systems Sandbox where you tune the flows into a "bathtub" and predict the shape of what happens over time.
Predict first, then find out
Every lab asks you to make a prediction before it reveals the answer — even a wrong guess helps the idea stick — and always ends by explaining why, not just whether you were right. Curriculum is aligned to NGSS Systems & System Models and the widely used Habits of a Systems Thinker (reinforcing vs balancing loops, behavior-over-time graphs, stocks & flows).
