In Tech A, the students will be able to design and construct different types of structures. They will design and construct a truss bridge, a tower and test these for efficiency. They will design and construct a catapult and test it for distance and accuracy. Students will research different types of structures and build samples such as a balsa wood delta airplane which will be tested for flight time while learning the different parts of an airplane. Students will increase critical thinking skills in determining flight length and reasons for greater and shorter flight patterns
