We made paper planes to learn about flight.
We found out that the wings have to be symmetrical - balanced on each side.
Wind can affect flight. A tail wind gives you an extra boost, so having the wind behind us makes them go further.
Some planes glide - these are called gliders - they don't have engines and propellers.
Sometimes paper planes with large wings, didn't fly very well because the wind caught the wings and pushed them back.
A paper plane that had a blunt nose worked better - we think this is because it made the front heavier and go further.
To many folds makes it slow down as the wind has more surfaces to catch.
The paper plane needs to be stiff not flimsy. If it was flimsy it would just crash, it had no resistance against the wind.
Lane had a skinny plane and it flew further and throwing it upwards also helped.
