Activity 1: X-Gliders Lesson Objective: Campers will learn about the forces of flight‚ weight and balance when they construct a glider. As they improve the design of their glider they will understand that a variable is a single change in the engineering. Set-Up: Each student will need two foam trays‚ a plastic knife and an x-glider template. Materials for weight and balance can be distributed at a communal table. Demo and discussion: Start off the lesson by asking your campers‚ “What are gliders

the airfoil and the pattern of airflow around it have profound effects on the lift and drag generated by the wing. Aircraft designers choose a particular airfoil shape for a wing in order to optimize its lift and drag characteristics to suite the requirements for a particular mission. It is essential that an aircraft designer understand how the changes that occur in air as it flows past a wing create lift and drag‚ and how airfoil shape influences this process. Figure 3.1.

Cricket field and Drag strip on Pond Island Bad or Good Idea? Is it a good idea to build another cricket field and a drag strip on St.Maarten? Yet again another controversial subject has struck St.Maarten. Should we fill up the pond‚ which once upon a time had people at war for its ability to bear the once valuable and costly mineral which is salt‚ even though it is no longer able to? The cricket field: Another cricket field on St.Maarten is a situation that would be considered

Breast Stroke The breaststroke is a swimming style in which the swimmer is on his or her chest and the torso does not rotate. It is the most popular recreational style due to its stability and the ability to keep the head out of the water a large portion of the time. In most swimming classes‚ beginners learn either the breaststroke or the front crawl first. Since the breaststroke can be swum with the eyes almost always above water‚ it is important in lifesaving‚ as it allows the rescuer to approach

Cruise: this is where the aircraft’s flight forces are at equilibrium; thrust is equal to drag and lift is equal to weight. The aircraft neither accelerates nor decelerates. Dive: this is the
