Evaluate a design or object using criteria. Kids judge their egg protectors and planes against a simple pass-or-fail test, then improve them.

The Texas Essential Knowledge and Skills (TEKS) for Science outcome 4.2(D) (Scientific and engineering practices) for Grade 4 says: “Evaluate a design or object using criteria. Kids judge their egg protectors and planes against a simple pass-or-fail test, then improve them.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Texas Essential Knowledge and Skills (TEKS) for Science.

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.

  • How does a rocket push itself into space? 45 min

    Kids build a balloon rocket that zooms along a string between two chairs, then run a fair test on how much air goes in the balloon. They finish able to explain action and reaction: the balloon pushes air back, and the air pushes the balloon forward.
