In this content resource students are challenged to design a super-slow helicopter. Students are given a template for a paper helicopter. They must then determine which features of the helicopter can be modified to slow its descent. This activity would fit nicely into a larger lesson or unit on Newton's laws of motion. (author/ts)

Ohio Science Academic Content Standards (2002)
Physical Sciences
Benchmarks (6–8)
B.
In simple cases, describe the motion of objects and conceptually describe the effects of forces on an object.
Benchmarks (9–10)
D.
Explain the movement of objects by applying Newton's three laws of motion.
Benchmarks (11–12)
D.
Apply principles of forces and motion to mathematically analyze, describe and predict the net effects on objects or systems.
3.
Explain that an unbalanced force acting on an object changes that object's speed and/or direction.
21.
Demonstrate that motion is a measurable quantity that depends on the observer's frame of reference and describe the object's motion in terms of position, velocity, acceleration and time.
23.
Explain the change in motion (acceleration) of an object. Demonstrate that the acceleration is proportional to the net force acting on the object and inversely proportional to the mass of the object. (Fnet = ma. Note that weight is the gravitational force on a mass.)
25.
Demonstrate the ways in which frictional forces constrain the motion of objects (e.g., a car traveling around a curve, a block on an inclined plane, a person running, an airplane in flight).
5.
Use and apply the laws of motion to analyze, describe and predict the effects of forces on the motions of objects mathematically.
Science and Technology
Benchmarks (6–8)
B.
Design a solution or product taking into account needs and constraints (e.g., cost, time, trade-offs, properties of materials, safety, aesthetics).
Benchmarks (9–10)
A.
Explain the ways in which the processes of technological design respond to the needs of society.
