Glider

PBGR:  Practice 1 Asking Questions and Defining Problems

Students at any grade level should be able to ask questions of each other about the texts they read, the features of the phenomena they observe, and the conclusions they draw from their models or scientific investigations. For engineering, they should ask questions to define the problem to be solved and to elicit ideas that lead to the constraints and specifications for its solution

Curriculum focus of:

Identifying the problem

Generating solutions

Selecting the best solution

Prototyping

Making Predictions/Testing solution.

Analyzing results

Making improvements to meet the goal

Working towards proficiency in standards

Please complete the pre assessment on flight below.

Directions
1) Follow the link below to discover how a glider flies and the forces that act on it which enable it to       do so.
2) In order to design a successful glider it is imperative that you are able to principles of flight with the acting forces, Please create a working glossary of terms in your transportation folder and define each as they relate to flight according the discussion and reading.

• Lift
• Drag
• Weight
• Fluid
• Bernoulli's Principle
• Force 

How does a glider actually work.  


Once you have defined your terms, take the challenge and build a paper glider.

Problem:  Make a glider that will create enough lift to fly for the longest amount of time.

Criteria: Use the defined glider design first.  Experiment with your own design next.

Procedure: 
1) Drawing upon your knowledge of flight principles, On a google doc, with your terms, create a chart and make a prediction on the flight times.  
2) Once you have make your prediction make three flight attempts, timing and recording each one Before you make any adjustment to your glider. 
3)  Record any necessary adjustment to your glider you feel will improve the glider/plane performance answering the following.

What adjustments did you make to your glider?
Why specifically led you to make the changes?
What do you expect to see as a result of the change?
What made your plane aerodynamic?
How did flight patterns change with the different variables?

4)  Test again and record the result.
