Build It, Launch It Grades K–5

Egg drops, paper planes and balloon rockets, done properly at home. Three engineering challenges where kids build, test, fix and explain the pushes and pulls behind what happened.

• Can you drop an egg without breaking it? 60 min

  Kids design an egg protector on a materials budget, test it from a low height first and work up, and fix what fails. They finish able to explain why a soft, slow stop saves the egg.

• What makes a paper plane fly farthest? 45 min

  Kids fold two different paper planes and run a fair test, changing one thing at a time: first the design, then the throw. They measure three throws each and explain the flight using lift, drag, thrust and gravity.

Monsoon Science: Rain, Sun and the Nón Lá Grades 3–4

Science and English together, for English learners (CEFR A2–B1). Why is the Vietnamese nón lá shaped like a cone? Students build paper hats, test them in 'monsoon rain' and 'midday sun', and find the best shape for a rice farmer.

• How does a nón lá keep a rice farmer dry? 60 min, or two 35-minute periods

  Science and English together, for English learners at CEFR A2–B1. Teams build paper cone hats of three shapes, test them under 'monsoon rain' and 'midday sun', and measure how far each one sends the water and how much shade it makes. Then they design the best hat for a rice farmer.
