Activities are based on techniques that physicists use to make discoveries. We have included activities that use data from Cosmic Ray studies and activities that help students explore the concepts in this experiment.

Signal and Noise: Cosmic Muons

In this introductory tutorial that, students learn about how to distinguish muon signals from background and instrumental noise.

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 Muon Lifetime

Students learn how physicists measure muon lifetime.

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 Rays and the Sun

Students search for a specific data file in the Cosmic Ray e-Lab and look for evidence of the passage of the sun in the flux measurements derived from this file. 

Mass of U.S. Pennies

Students create and interpret a histogram of penny masses.

Rolling with Rutherford

Students use statistics to make an indirect measurement they can easily confirm.

Quark Workbench 2D/3D

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

Cosmic Ray e-Lab

Students experience the excitement of scientific collaboration in this series of investigations into high-energy cosmic rays.

Calculate the Top Quark Mass

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