Professional Commentary

Students explore Bernoulli's Principle and relate what they have learned to the principles of flight. The lesson involves an opening discussion, three student activities, a whole class demonstration, and a closing discussion. This lesson is part of a larger website related to the PBS Chasing the Sun program. Additional features of the site include an aviation timeline, planes, innovators, companies, related web links, and additional resources. Ohio's 8th grade Science Standards emphasize forces acting on the object that change its speed or direction. (author/ts/nm)

Science Inquiry and Application
Grade 8
Physical Science
Forces and Motion
1. 
Forces between objects act when the objects are in direct contact or when they are not touching.
2. 
Forces have magnitude and direction.
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.
Grade Level Indicators (Grade 8)
3.
Explain that an unbalanced force acting on an object changes that object's speed and/or direction.
Grade Level Indicators (Grade 9)
22.
Demonstrate that any object does not accelerate (remains at rest or maintains a constant speed and direction of motion) unless an unbalanced (net) force acts on it.
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.)
Scientific Inquiry
Benchmarks (9–10)
A.
Participate in and apply the processes of scientific investigation to create models and to design, conduct, evaluate and communicate the results of these investigations.
Grade Level Indicators (Grade 9)
3.
Construct, interpret and apply physical and conceptual models that represent or explain systems, objects, events or concepts.
6.
Draw logical conclusions based on scientific knowledge and evidence from investigations.
Grade Level Indicators (Grade 10)
4.
Draw conclusions from inquiries based on scientific knowledge and principles, the use of logic and evidence (data) from investigations.
