Kavi's Boat Challenge
Teddy 🧸 wants to carry three marbles 🔵 across the water pool. "First we draw a plan 📝," hoots Kavi, "then we build 🔨 it, test 🧪 whether it floats and carries the load — and if it sinks, we change one thing 🔧 and test again. That's how real designers work!"

2Which plan is better?A plan should fit the job AND the material. Predict the better plan, then tap to check why! Tap Next test for more.

A peek inside
Plan: before building a tower for Teddy, what should Kavi do first?
A good designer draws a plan first and labels the parts, so problems show up before building.
