# QuarkNet Data Portfolio

A collection of proven instructional activities developed around data strands that help students develop an understanding about how scientists make discoveries.

The Data Portfolio organizes activities by data strand and level of student engagement. Activities differ in complexity and sophistication—tasks in Level 1 are simpler than those in Levels 2 and 3. While each level can be explored individually, students that start in one level and progress to more complex levels experience increasingly engaging and challenging tasks. Teachers select activities to offer a learning experience of an appropriate length and level for their students.

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

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

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." |
||||||

ATLAS Data Express ATLAS Data Express is a short investigation in which students inspect and characterize Z events in the LHC and distinguish muons from electrons. |
||||||

Mean Lifetime Part 2: Cosmic Muons Students learn how physicists measure muon lifetime. |
||||||

Calculate the Top Quark Mass Students use conservation laws and vector addition to calculate the top mass from event displays. |
||||||

ATLAS W-path Masterclass Students are physicists for a day at a university or lab where they work with physicists to how to analyze real particle physics data in the form of event displays. |
||||||

CMS Masterclass J/Psi Students are physicists for a day at a university or lab where they work with physicists to learn how to analyze real particle physics data in the form of event displays. |
||||||

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. |
||||||

Making it ‘Round the Bend - Quantitative Students measure the effects of electric and magnetic fields on particles. |
||||||

Mapping the Poles Students explore some basics of magnetic fields that can be related to experimental particle physics. |
