Week 1
Lesson 1
Dark Matter
Dark Matter is a substance thought to account for roughly 85% of the matter in the universe. We'll explore the astrophysical observations that led scientists to propose the existence of Dark Matter. Dark matter is called "dark" because it does not appear to interact with the electromagnetic field - it does not absorb or reflect light, and does not appear to interact with known matter except through gravity. 
Lesson 2
Dark Energy
Dark Energy is a speculative form of energy that may effect the universe on the largest scales. The first observational evidence for its existence came from supernovae measurements, which showed that the universe does not expand at a constant rate; rather, the expansion of the universe is actually accelerating. Since the 1990s, dark energy has been the most accepted premise to account for the accelerated expansion. 
Lesson 3
The Standard Model of Particle Physics
Session 3 explores additional subatomic particles beyond the electron, neutron and proton, including quarks, bosons and neutrinos, introducing students to the Standard Model of Elementary Particles. We'll discuss how protons are neutrons are made of smaller particles (quarks), and the various types of quarks. We'll also explore emerging theories about additional subatomic particles that may be waiting to be discovered. 
Lesson 4
What is Antimatter?
Is Anti-matter real, or the stuff of science fiction? Anti-matter is actually REAL, and is composed of subatomic particles that have the opposite electrical charge of regular subatomic particles. Each type of subatomic particle has an anti-equivalent, such as anti-electrons (called positrons) and anti-protons. First proposed in 1928 by Paul Dirac, anti-particles are being produced and studied at the large Hadron Collider operated by CERN.
