Particle Physics for Everyone – A Close-up of the “Particle Zoo”

Expanding Your Horizons in Science and Mathematics

What is Physics?What is Physics?

Physics deals with the way the universe works at the most basic level– This means that the same physics

laws apply to a snowflake falling, the eruption of a volcano, the explosion of a distant star and the flight of a butterfly

Then, what is Particle Physics?Then, what is Particle Physics?

Particle Physics deals with the smallest, most basic particles of the universe

Protons and neutrons contain particles called quarks and force carriers. Electrons are particles called leptons.

What is the smallest thing you know of?

The atom is made of even smaller particles.

You will need these materials: • Partner• Flashlight• Piece of clear plastic optical fiber

Follow these directions: 1. Shine the flashlight into one end of the fiber.2. Look at the other end. What do you see?3. Now twist the fiber any way you want to and shine the light in one end.

What do you see at the other end? (Do not bend the fiber completely.)

How do we see the “animals”?How do we see the “animals”?You will need these materials: • One shoe box lid, turned upside down• Cups to hold the shoe box lid up• Magnetic marbles• Ordinary marbles• Iron filings

Follow these directions: 1. Place box lid upside down on the table and insert cups at each corner to

raise it just enough so that any of your marbles can roll under it. 2. Sprinkle iron filings in the lid so as to cover all of it. This is your simulated

detector. 3. Roll a magnetic marble rapidly under this simulated detector. What do you

see?4. Roll an ordinary marble rapidly under this simulated detector. What do you

Lessons Learned

Middle school girls can be motivated to learn about particle physics

Physics does not have to be intimidating

Girls appreciate seeing that women are involved in physics research
