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


            Ripple tanks

            Double slit


            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?
