Astro Academy: Principia
From December 2015 until May 2016 the first British ESA (European Space Agency) astronaut Tim Peake lived and worked on the International Space Station as part of Expedition 46/47.

His mission, called Principia, included work on a wide variety of education projects alongside his day-to-day work for ESA and in collaboration with other space agencies on the ISS.

In support of Tim's mission, various different organisations collaborated with the UK Space Agency on related educational resources to take advantage of the opportunities that the mission provided.



For one of these education projects the National Space Academy designed and built a set of kit for a series of simple demonstrations that Tim has conducted and filmed whilst on the International Space Station (ISS) to illustrate fundamental aspects of physics and chemistry curricula, comparing results in micro-gravity with those in classrooms on Earth for the project Astro Academy: Principia.

The demonstrations cover secondary science topics such as circular motion, collision physics, kinetic theory of gases and harmonic motion, using systems which act differently under Earth gravity than in the micro-gravity environment on the ISS, where the theory is beautifully clear.

Tim's demonstrations have been used alongside Earth-based filming to create a series of five films, accompanied by written teacher guides, using the classroom expertise of the National Space Academy, whose UK wide team is comprised of award winning and Ofsted rated "outstanding" subject specialist teachers with years of experience and excellent records of exam results.

The videos and accompanying materials will be available to teachers for many years to come and will be a lasting legacy of Tim's mission.

What does "Astro Academy: Principia" mean?

The project's name incorporates Tim Peake's mission name, Principia, which he chose in homage to the great scientist Sir Isaac Newton, and in particular Newton's great work Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), commonly referred to as "Principia".  The books that make up Principia include what is arguably Newton's most famous work and the basis of classical physics: Newton's Laws of Motion.

The "Astro" in Astro Academy refers to the suffix used by astronauts on their twitter handles (eg @Astro_TimPeake) as well as the word astronaut itself – the "astro" part coming from the Greek word astron meaning star (and naut coming from nautes meaning sailor).  The inclusion of the word Academy is a reference to the National Space Academy model of supporting teaching and learning by using space contexts to tackle curriculum topics in the sciences and maths.

Astro Academy: Principia will demonstrate some of Newton's laws and other fundamental principles of physics and chemistry in a way that Newton and subsequent scientists could only have imagined.
