Particle physics concepts are important in astrophysics especially in trying to determine how conditions during the first few minutes of the Big Bang have governed the formation and nature of matter today. The activities below provide an introduction to the Standard Model, a current theoretical framework that describes the interactions between the elementary building blocks of matter.
ACTIVITIES on Particle Physics

 The Standard Model
Includes various activities introducing the components of the Standard Model.

 Activity Two - Psyching Out the System
This puzzle shows the challenge that particle physicists face when trying to answer what are "building blocks" of the universe and what are the interactions between these objects?

Activity Five - The Rules of the Game
This activity will give you the chance to discover rules, called conservation laws, that play a crucial role in the study of particle physics.
Beyond the 1930s Atom
This unit introduces students to the Standard Model of Fundamental Particles and Interactions and conservation laws which govern the consistent patterns in physical processes. The unit ends with a card game on particle physics as well as guidelines that students may use to create learning games of their own on various topics.

Lab 5: Active Galactic Nuclei
Tutorial and online lab. Take notes and do the exercises as you go. Click to open the virtual laboratory frameset at the bottom of the page and then choose "Labs for Semester 2" and then "Lab 5: Active Galactic Nuclei" from the menu on the right. Print out the answer sheet .
Quasars
Read the information found on the following websites. Write a page on quasars explaining current theories on what they are, their relationship to black holes and why quasars give evidence for the Big Bang Theory.
Chandra: Quasars and Active Galaxies
Imagine! Active Galaxies and Quasars
Imagine! Active Galaxies and Quasars, Adv. Level
Frequently Asked Questions About Quasars
Quasars (Lab 13)
In this lab you will learn about quasars, the most distant known objects in the universe. Astronomers' knowledge of quasars is based on being able to determine distances to them. You will use the concept of the Doppler effect (you were introduced to this concept in the Binary Stars lab) to determine distances to quasars. In the process you will learn about the extreme properties of these enigmatic objects.
