# Standard Model

## Plotting a Concensus

The purpose of this activity is to come to a consensus for the “best” value for the mass of the Z Boson.

## Particle Transformations

Students discover the rules of particle transformations using transformation diagrams.

## Z Mass Spreadsheet Extension

Students use spreadsheet coding to determine the Z Mass for a large data set.

## The Case of the Hidden Neutrino

Students use momentum conservation to examine the decay of top-antitop pairs to determine what is missing from the event.

## Shuffling the Particle Deck

Teams of students organize cards depicting fundamental particles based on their characteristics. This activity is a foundation for learning about the Standard Model and parallels the methods used by scientists to organize the elements into the period table.

## Quark Workbench 2D/3D

Students use Standard Model rules to build hadrons and mesons from quarks.

## Calculate the Top Quark Mass

Students use conservation laws and vector addition to calculate the top mass from event displays.

## Calculate the Z Mass

Students use conservation laws and vector addition to calculate the Z mass from event displays.
