Introduction
Introduction
Humans have long dreamed of traveling into space. Greek mythology tells of Daedalus and Icarus, a father and son who took flight using wings made of feathers and wax (Figure below). Icarus, thrilled with the feel of flying, got too close to the Sun, the wax melted, and he fell into the sea. In a time before airplanes and hot air balloons, we can relate to the excitement Icarus would have felt. Much later, science fiction writers, such as Jules Verne (1828–1905) and H.G. Wells (1866–1946), wrote about technologies that explore the dream of traveling beyond Earth into space.

Humans did not reach space until the second half of the 20th century. However, the main technology that makes space exploration possible, the rocket, has been around for a long time. A rocket is propelled by particles flying out of one end at high speed. We do not know who built the first rocket, or when, but there are records of the Chinese using rockets in war against the Mongols as early as the 13th century. The Mongols then spread rocket technology in their attacks on Eastern Europe. Early rockets were also used to launch fireworks and for other ceremonial purposes.
Rockets were used for centuries before anyone could explain exactly how they worked. The theory to explain rockets did not arrive until 1687, when Isaac Newton (1643–1727) described the three basic laws of motion, now referred to as Newton’s Laws of Motion:
An object in motion will remain in motion unless acted upon by a net force.
Force equals mass multiplied by acceleration.
To every action, there is an equal and opposite reaction.
Newton’s third law of motion is particularly useful in explaining how a rocket works.
After watching the video and reading about how rockets work - complete the 9 questions at the end of the reading. Put the questions and the answers on a google doc and link to slate.
(Keep in mind - a rocket could be a cool PT!)
Assignment 2: Complete the reading on satellites, shuttles and space stations. Complete the review and Explore more questions or take the self-practice. Self-practice you must score an 80% or higher.

Real Facts or Fake Facts? Compare two different "space movies or books". The performance task will be an in-depth research on multiple concepts about space portrayed within full-feature video productions. You will research a minimum of 10 principles of "science" that was used in the two videos; finding 5 errors displayed or portrayed in the movie and 5 correct scientific principles used in the video. Each science concept or theory must have evidence supporting the error/correctives of the principles.
The project will require a formal research write and model.
The model for this project is a presentation of findings: Infographic, Informational pamphlet, multimedia presentation
