# LIGO Strand Notes

LIGO—what levels are needed to have scaffolding—

Level 0—what is a histogram, identifying a peak, how do you make that measurement -dice

Level 1 –

Getting to science as inquiry, signal to noise, period motion

Currently Missing--  we need a tidy signal to noise activity.  Create a lab—

percent difference HERE   scaling on a graph

scaffolding for novice teachers—authentic science inquiry

Level 2 – examining the signals that have been historically created for Higgs and whether it is significant, Bin Size,  Here sigma or the significance of the outlying data

Level 3 is the e-Lab  getting back to supporting the facts.

It is time to update the data that is available in LIGO e-Lab to reflect the collision data between the two black holes detected in 2016

An advanced approach will be to use data with master class, CMS, to include noise vs. less noise

And this approach within Ligo that can be used more globally across other e-Labs, looking at data from other e-Labs to support this same enduring understanding

1.     What other supports can we provide to less-experienced teacher?

Next level for teachers—teachers modeling and engaging with authentic science for students.

We can produce an activity that grounds teachers and introduces students to authentic science practices.

Science as a way of doing things to learn things—frames of reference?  Period of a pendulum?

Birds eye view, what is the motion?  Motion on a

Motion of peak to peak, different frames of reference  can you merge your signal with other’s signal to get something that is real?

Supports to novice teachers is the process of getting the factors that do impact the period

And the signal to noise stuff is showing the data that mass is not a signal, length is

2.     Are there things that we can expand out sideways that we can address?

Periodic motion

Interferometry, interference, phase relationships

Beats/sound

Ripple tanks

Double slit

Diffraction

Totem master class—level 2 as well

Level 4 activity?—programming?

LIGO group  #1

Level 0—  dice histogram -  signal

Level 1 --  period of the pendulum inquiry

Scaffolded for novice science teacher for authentic way to learn science

Percent difference as signal to noise strand next step

Introduction to periodic motion, waves, phase, etc.

Level 2 – Does NOT currently exist—analyzing historical particle discoveries

Getting more advanced with signal to noise, sigma or other statistical analysis

Level 3 – Ligo e-Lab

Would LOVE to have the e-Lab now include the black hole collision data

Level 4 --  Programing as a way to access the data?
