"Rock-star physicist" Brian Cox talks about his work on the Large Hadron Collider at CERN. Discussing the biggest of big science in an engaging, accessible way, Cox brings us along on a tour of the massive project. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 15-minute video. Educators may use the platform to easily "Flip" or create their own lesson for use with their students of any age or level.

This features scientists and machines that explore the universe's tiniest particles. Follow a proton through the accelerator. Meet scientists at CERN. Hear why they search for the secrets of matter. Learn about the antimatter, the Big Bang, and other big ideas behind experiments at CERN.

This 13-minute video lesson shows how elements relate to atoms. The lesson includes the basics of how protons, electrons and neutrons make up an atom. [Chemistry playlist: Lesson 1 of 106].

This 21-minute video lesson introduces the atom, proton, neutron and electron. [Chemistry playlist: Lesson 2 of 106].

These pages invite students to test various particles for their decay products. Most particles studied by physicists are unstable; they decay. That is, given enough time by itself, one unstable particle will fly apart into two or more particles. By carefully observing and logically classifying these decays according to some well-understood laws of nature, particle physicists have been able to explain much about the fundamental structure of matter.

The computer will randomly pick an element and present you with that element's data from the Periodic Table of Elements. Use that information to answer the question that the computer asks about the number of protons, neutrons, electrons or nucleons (particles in the nucleus) that an atom of that element contains.

What happens to a racquetball when it gets very cold? What happens to neon gas when it gets very hot? In this experiment, liquid nitrogen and Tesla coils are used to study the effects of extreme temperatures on everyday objects.

Just how small are atoms? And what's inside them? The answers turn out to be astounding, even for those who think they know. This fast-paced animation uses spectacular metaphors (imagine a blueberry the size of a football stadium!) to give a visceral sense of the building blocks that make our world. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 5-minute video. Educators may use the platform to easily "Flip" or create their own lesson for use with their students of any age or level.

This lesson introduces the concept of electricity by asking students to imagine what their life would be like without electricity. Two main forms of electricity, static and current, are introduced. Students learn that electrons can move between atoms, leaving atoms in a charged state.

Students research the structure of salt to understand the difference between molecular compounds and ionic compounds

Nim is a game of logic and strategy. The goal of Nim is to be the player who removes the last of ten protons from the computer screen. A player must remove one or two protons during their turn. The player who removes the last proton wins.

Explores the interaction of radiation with matter at the microscopic level from both the theoretical and experimental viewpoints. Emphasis on radiation effects in biological systems. Topics include energy deposition by various types of radiation, including the creation and behavior of secondary radiations; the effects of radiation on cells and on DNA; and experimental techniques used to measure these radiation effects. Cavity theory, microdosimetry and methods used to simulate radiation track structure are reviewed. Examples of current literature used to relate theory, modeling, and experimental methods. Requires a term paper and presentation. The central theme of this course is the interaction of radiation with biological material. The course is intended to provide a broad understanding of how different types of radiation deposit energy, including the creation and behavior of secondary radiations; of how radiation affects cells and why the different types of radiation have very different biological effects. Topics will include: the effects of radiation on biological systems including DNA damage; in vitro cell survival models; and in vivo mammalian systems. The course covers radiation therapy, radiation syndromes in humans and carcinogenesis. Environmental radiation sources on earth and in space, and aspects of radiation protection are also discussed. Examples from the current literature will be used to supplement lecture material.

This module will introduce you to many of the basic properties of matter including atoms, ions, elements, molecules, and density. You will use real data from plasma physics research to further explore the basic properties of matter.
