The Quark Zoo Goal: Practice your ability to observe patterns as you interact with your new colleagues. Procedure: 1. Determine the rules by which quarks join with other quarks. 2. Record any other observations. 3. Record any questions your group may have as a result of your observations. Allowed Quark Groups: _ _ _ _ _ _ u u d u d u s u d d d c _ _ _ _ _ _ _ _ u s u u d u d b u b u u c _ _ _ _ d s c u d s u d d u d Rules: Observations: Questions: 1
Instructions for teacher to give to students: Materials: The Quark Zoo Teacher’s Notes & Set-up Many rules or discoveries in science result from the observation of patterns. At <strong>Fermilab</strong>, scientists energize protons and then smash them into energized antiprotons. The energy that results from this collision reorganizes into different particles. These particles are groups of quarks (one of the smallest building blocks of matter). Study the groups of quarks these scientists have seen. . . . Each group is given a Quark Zoo worksheet. You may also want to prepare a set of cards with each allowed quark group written on a card so that students could sort and categorize them during the activity. Results: 5 different quarks “Bar” only joins with an “antibar” or with two other “bars” u & d quarks are very common. Teacher Comments: There are six…u&d….s&c…b&t (NOTE: T is missing; discuss with students why it is hard to find; it’s not common.) Baryons vs. Mesons Protons vs. neutrons (Electrons are leptons.) . . . Now we can move onto the standard model!!! 2
