5-0-4a: Carry out, with guidance, procedures that comprise a fair test…

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.

Evidence Lab Grade 4

How do you know something is true? Students test a claim with their own measurements, find out why one result is never enough, and learn to tell strong evidence from weak.

• How do you know a fact is true? 45–60 min

  Students test an internet 'fact', that your arm span is exactly the same as your height, by measuring themselves and pooling the whole class's data. Then they rank different kinds of evidence from strong to weak and decide how true the claim really is.

• Why do scientists repeat their tests? 45–60 min

  Students build two paper helicopters, one with long wings and one with short wings, and time each one falling five times. They find that the same drop never gives exactly the same time, and use their repeated trials to decide whether the wing change really made a difference.
