Paper Helicopters

Review

What did they notice about the spins for each helicopter?

REVIEW

Did they spin clockwise or anticlockwise?

How can you change the spin?

Does the weight (the number of paper-clips on the stem) change the spin?

Which combination made the best spinning helicopter?

Helicopters – some possible outcomes

Two similar-sized helicopters

add paper clips to one: the heavier one spins more and reaches the ground first.

make one with longer rotor blades than the other: the one with the longer rotor

blades takes longer to reach the ground (more surface area to experience air

resistance - think of a parachute).

One large and one small helicopter

Small one reaches the ground first (less surface area to experience air resistance).

The children could draw annotated diagrams showing how their different helicopters

ASSESSMENT

fell. They could be given other helicopters and asked to predict how they would fall.

Concept-mapping could be used as means of the teacher building up an

understanding of how and what the children understand about ‘forces’.

Various graphs could be drawn, e.g.

FOLLOW-UP ACTIVITIES

Length of rotor blades/number of spins

(height and no. of paper-clips kept

constant)

Number of paper-clips/number of

spins (length of rotor blades kept

constant)

The children could be asked:

What else would you like to find out?

How would you find it out?

This would encourage them to design their own

investigation.
