# QuarkNet Data Portfolio

The Data Portfolio is a compendium of activities organized by data strand and level of student engagement. Follow the links provided for information about using the Data Portfolio to plan your students’ experience. Level descriptions explain the data analysis skills that students apply at each level: tasks in Level 0 are simpler than those in Levels 1 and 2. While each level can be explored individually, students who start in one level and progress to more complex levels experience increasingly engaging and challenging tasks.

Sample pathways provide a progression of activities to help students better understand practices that lead to discovery. Each sample pathway is matched to a particular data strand and a particular skill set.

Activity Name | Data Strand | Level | NGSS Practices | Topic |
---|---|---|---|---|

Mapping the Poles Students explore some basics of magnetic fields that can be related to experimental particle physics. |
LHC | Level 0 | 4, 6, 7 | Lorentz Force, Measurement, Motion of Charged Particles, Other |

Signal and Noise: The Basics Students analyze signals and noise first in audio and video forms and then look at signals and noise from physic measurements. |
Cosmic Ray, LHC | Level 0 | 4, 5, 6, 7, 8 | Data Analysis, Measurement |

Quark Workbench 2D/3D Students use Standard Model rules to build hadrons and mesons from quarks. |
Cosmic Ray, LHC | Level 0 | 2, 6 | Particle Composition |

Making it ‘Round the Bend - Qualitative Students explore the effects of electric and magnetic fields on particles. |
LHC | Level 0 | 4, 5, 7 | Electric Potential, Lorentz Force, Motion of Charged Particles |

Dice, Histograms & Probability Students roll dice, record the resulting individual values as well as the sum of the values, create histograms of the data and develop insight into the concept of “degrees of freedom." |
Cosmic Ray, LHC | Level 0 | 1, 2, 3, 4, 5, 6, 7, 8 | Data Analysis, Measurement |

Mass of U.S. Pennies Students create and interpret a histogram of penny masses. |
Cosmic Ray, LHC | Level 0 | 1, 3, 4, 7 | Data Analysis, Measurement |

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. |
LHC | Level 0 | 1, 2, 4, 5, 6, 7 | Particle Composition |

Calculate the Top Quark Mass Students use conservation laws and vector addition to calculate the top mass from event displays. |
Cosmic Ray, LHC | Level 1 | 1, 4, 5, 7 | Data Analysis, Momentum Conservation |

Rolling with Rutherford Students use statistics to make an indirect measurement they can easily confirm. |
Cosmic Ray, LHC | Level 1 | 1, 3, 4, 7 | Data Analysis, Measurement |

Making it ‘Round the Bend - Quantitative Students measure the effects of electric and magnetic fields on particles. |
LHC | Level 1 | 4, 5, 6, 7 | Data Analysis, Electric Potential, Lorentz Force, Measurement, Motion of Charged Particles |
