Paper Aeroplane Testing Lab
Three designs, one tape measure, and an argument about which flies furthest.
Fold several designs and actually test them properly. The measuring is what makes it stick.
ما تحتاجه
- paper
- a tape measure or ruler
- a pen
طريقة التنفيذ
- Fold three different aeroplane designs. A dart, a glider, and one of their own invention.
- Mark a throwing line on the floor.
- Each plane gets three throws. Measure and write down every distance.
- Work out which design won on average, not on its best throw.
- Change one thing about the losing plane and test it again.
لماذا هذا مفيد لهم
Averaging three throws instead of celebrating the best one is the first real lesson in fair testing, and it is a genuinely difficult idea for children. Changing one variable at a time afterwards is the scientific method in miniature.
