The worksheet in is an introduction to this lesson on the forces affecting the flight of an airplane. Give a copy to each student and have them use the bookmarks provided on the worksheet to complete their Web search.
After students have had a chance to complete the Web search and have learned more about the forces affecting the flight of an airplane, they can do several experiments on the force of "lift."
For the first experiment, take two sheets of paper of the same size. Crumple up one sheet and leave the other flat. Predict which one will reach the ground first. Drop them from the same height at the same time and watch them fall to the ground. The flat sheet will fall more slowly because it has more surface area and therefore more air resistance. Objects that have more surface area generate more lift. But there are other factors that also affect lift.
The second experiment uses the airfoil to illustrate the Bernoulli Principle. Daniel Bernoulli
(1700-1782), a Swiss mathematician, found that fast-moving
air causes less pressure than slow-moving air. Notice on the airplane wing
that air flowing over the upper surface of the wing must travel farther than
the air along the bottom of the wing in the same amount of time. This
difference in speed creates a region of low pressure above the wing and a
region of high pressure below the wing. Since there is more
pressure on the underside of the wing, the plane is lifted into the region
of low pressure. Take a hair dryer and turn it on high speed. Point the hair dryer straight up and place a Ping-Pong ball in the airstream from the dryer. The ball will appear to float there. This is a result of the Bernoulli Principle. The airstream flows faster around the curved sides of the ball. The air pressure here is
lowered, and the higher air pressure outside the airstream pushes the ball
into the middle of the airstream. The push of the air against
the ball (lift) and the weight of the ball (gravity) combine to make it hover in midair.
What happens to the ball if you tilt the hair dryer no more than 45 degrees? Why?
(The ball will stay in the stream until at 45 degrees the force of gravity overcomes lift and causes the ball to fall)
For the third experiment give the students a flexible straw and a small Styrofoam ball. See if the students can replicate the experiment done with the hair dryer. The principles that apply are the same.
Obtain a copy of the paper airplane design. Create a paper airplane according to these directions. Fold one way along the black lines and the other way along the gray lines. The black lines should be on the outside of the folds and the gray lines should be on the inside of the folds. Make the folds in order from 1 to 4. Keep your creases crisp. Bend up the two triangular wings so that they are horizontal and the model looks like an airplane. Send your airplane on a test flight.
A small piece of tape on the top of the paper airplane will hold the wings together and make it fly better. Try paper clips at various points on the airplane and see how this affects its flight.
Challenge each other on how far your airplanes will fly or how fast they will fly.
Students could try to fly their paper airplanes through hoops that someone holds up or that are suspended somewhere. These hoops could be made from coat hangers. Another contest might be to try to make a basket like in basketball, using the hair dryer and Ping-Pong ball. Tilt the dryer and try to make a basket.
Students could go to the Web site Airport http://www.selah.wednet.edu/LINKS/aviation.html/index.html to research the history of flight and write a report.
Students could go to the Web site Artie the Airplane Coloring Book http://www.artietheairplane.com/coloringbook/coloring.html to print and color pictures.
Students could go the Web site Boeing Kids Page http://www.boeing.com/companyoffices/aboutus/kids/ to play word games and other activities.
Students could go to the following Web sites for experimentation with other paper airplane designs. Airport http://www.selah.wednet.edu/LINKS/aviation.html/, Learn2 Make Paper Airplanes http://www.paperairplanes.co.uk/, and Phoenix Sky Harbor Airport's Kid's Section http://www.phxskyharbor.com/skyharbr/kids/science.html.
Students often work most effectively in small groups to develop
projects. Encourage them to share what they are learning with each other, as often explaining things to another person helps clarify one's own understanding of a concept.
Give students time to discuss what they are learning. The lesson activities will be most beneficial when the students have some background exposure to the topics.
Encourage students to support their views with evidence from the sources they are researching.
The use of different symbolic representations such as art and music is extremely helpful in integrating knowledge. Encourage students to think across disciplines.
One Computer in the Classroom
If you have access to one computer in your classroom, you can organize your class in several ways. Divide your class into two groups. Instruct one group to do paper research while the second group is working on the computer. Bring in books, encyclopedias, and other materials from the library for the group doing paper research. Lead the group working at the computer through an Internet search or allow the students in the class to take turns. (Always have a set of bookmarks ready for the students before they start working on the computer, in order to show them examples of what to look for.) When the groups have finished working, have them switch places.
If you have a big monitor or projection facilities, you can do Internet research together as a class. Make sure that every student in your class can see the screen, go to the relevant Web site(s), and review the information presented there. You can also select a search engine page and allow your students to suggest the search criteria. Again, bookmark and/or print the pages that you think are helpful for reference later.
Several Computers in the Classroom
Divide your class into small groups. They can do Internet research using pages you have bookmarked. Group members should take turns navigating the bookmarked sites.
You can also arrange the computers so that each is dedicated to certain sites. Students will then move around the classroom, getting different information from each station.
Using a Computer Lab
A computer center or lab space, with a computer-to-student ratio of one to three, is ideal for doing Web-based projects. Generally, when doing Web-based research, it is helpful to put students in groups of three so they can help each other if problems or questions arise. It is often beneficial to bookmark sites for students ahead of time.
