Two fold guides, a flight log and a taped runway down the hallway. Fold, throw, measure, change one thing, throw again - it is a real experiment and they do not notice.

This started on a rainy Sunday with one paper plane and ended with masking tape all down the hallway and a leaderboard on the fridge.
What surprised me was the measuring. My son wanted to know exactly how far each throw went, and then he started changing one fold at a time to see what happened. That is science, and I did not have to say the word once.
The flight log is the part that makes it last past lunch. Numbers on paper turn throwing into a project.

Print the fold guides and make one of each plane yourself first, slowly, so you can show the tricky fold.
Fold the Dart together following page one. Press every crease hard with a thumbnail - sloppy folds are why planes dive.
Fold the Glider from page two. It is the same start and a different nose, which makes the comparison fair.
Tape three lines across the hallway floor and label them with the runway markers from page four.
Three throws each, from the same spot, standing the same way. Write every distance in the flight log.
Now change exactly one thing: add a paperclip to the nose, or bend the back edges of the wings up by a few millimetres.
Throw three more times and write it down. Ask which change helped, and why they think so.
Finish with the distance record and the hang-time record - count the seconds out loud. Different planes usually win each one.

Four pages: step-by-step fold diagrams for the Dart and the Glider, a flight log for distances and hang times, and printable runway markers.
Coloured origami paper on Amazon
Thin square paper folds crisper than printer paper and gives every child their own colour, which quietly ends the whose-plane-is-whose argument.

Insist on the same throwing spot and roughly the same throw, or the results mean nothing and the arguing starts. If every plane dives, the nose is too heavy or the folds are uneven - refold rather than adding more tape.
