This week in tech we reviewed the forces of flight. The first day we went out to test fly paper airplanes. Made a modified dart, which was just a heavier nose (see image below). My airplane went relatively far. The next day we learned about the 4 forces of flight, and I learned about gliders. Gliders are made to be lightweight and to glide without an engine or thrust. They rely on manipulating the air flow to stay up in the air. The next few days we worked on orthographic drawings, or blueprints. I drew an orthographic drawing of a warehouse, and learned how to use guiding lines to draw the blueprint.
