7. Concept of Balanced Forces and Gravity Center
Session 1: Find the gravity center of an object
Objective 1: To understand that a two-dimensional object has a point of equilibrium.
Session 2: Displacement of a plane in the three dimension space
Objective 1: To determine in which direction a plane is able to move.
Objective 2: To investigate that changes of direction happen around one point, which is the gravity center.
Session 3: Paper planes and direction
Objectives 1: Build and Fly a paper plane
Objective 2: Changing the Flying direction of a paper plane
