Description
Welcome to the Johns Hopkins University QuarkNet center. We meet on the campus of JHU and serve teachers in the surrounding area.
Searching for Gravitational Waves in Noisy Data - A Classroom Activity
In this activity students will search for the evidence of simulated gravitational waves in noisy data sets. Although the activity's discussion centers on the science of gravitational waves, the method of data analysis that the students will encounter is used across the sciences.
Learning objectives, connections to standards, and classroom worksheets for this activity were prepared by Dale R. Ingram of the LIGO Laboratory.
The LIGO mirrors
No events were detected at LIGO, until they made some upgrades such as: re-examined the coating and size of the mirrors. They looked at the how a laser beam can slightly heat and deform mirrors, while also causing them to move a tiny distance. So they decided to use heavier mirrors to cut down on the noise that the lighter mirrors generated. So the original 11-kg mirrors with a 25 cm diameter were upgraded to 40-kg fused silica mirrors with a 35 cm diameter.

How I use the cosmic e-Lab in my IB classroom (3-day lesson plan)
Here is a Google Slides presentation about a 3-day lesson plan I did with my IB Physics seniors with the cosmic ray e-Lab. I have a muon detector in my classroom, so we use that, but you don't need a physical detector to do this lesson sequence -- you can just grab data from the e-Lab website from schools around the country.

This lesson was in conjunction with our unit on Special Relativity. The purpose of this lesson sequence was to illustrate one famous piece of experimental evidence which is in agreement with the very non-intuitive notions of time dilation & length contraction. In other words: how do we know this Special Relativity stuff is true?
Mechanical Universe - college version videos
This is the college or AP C (with calculus) version of the video series that Tim Durkin was talking to us about. The entire video series is available from Caltech on YouTube through here:
